Exhaust/Header Mod advice

[windyzz]

Hi guys,

I'm looking at modding my exhaust/header (cheap budget :P)

Requirement:
1. I don't want to lose the raspy noise (most aftermarket catback removed the original rasp sound) -Except kapristo and kreissieg (but they are tooooooo Expensive :( )
2. Not too loud (somewhere in between resonated stock and non-resonated stock)
3. Keep the flapper mod

I can't seems to find any solution for it :confused: :'(
Any advice,

Thanks,
Cheers.

windyzz,

This is for the R?

[windyzz]

Yup Yup Yup :)

[Frenchie]

I would suggest Supersprint exhaust, retains its raspiness but yet increase its volume. Prob looking at the $2k+ ...

Or Milltek exhaust a little more throaty in sound and pretty sure they make headers as well.

Both have the option of res/non res....

[windyzz]

Cool Thanks :)

Any place/shop in sydney that you know sell supersprint/milltek ?

thanks

[Frenchie]

Here we go...

Milltek - try Ian Link (http://www.rennenhaus.com.au/)

Supersprint/ Milltek - Wal Euroexhaust (http://www.euroexhausts.com.au/)

Supersprint/ Milltek - Thomas Ramspeed (http://www.ramspeed.com.au/)

Lucas advises me to not bother with headers as they are a bit hit and miss on our cars. Not worth the cash for the gains IF any. Might lose power.

high flow cats could be worthwhile, and if you want to keep the stock flapper, you are really limited to only changing the centre resonator on the stock system. ECS tuning has a resonator delete pipe for sale, or you could go to your local exhaust place and tell them to cut it out and replace with a pipe.

[Pharkus]

I'm saving up for a Capristo or Kreisseg...should be about 2015 by the time I can afford them >D

I would suggest that you take a look at youtube and search for the exhausts mentioned to get an idea of the sound. With an .:R just don't expect too much in terms of performance improvement with an exhaust. You really are just looking at enchancing the sound.

[Frenchie]

Agree with Terence, I have heard mixed reports with headers and personally wouldnt mess around with it.

Come on Pharkus, break that piggy bank :)

[windyzz]

Thanks for the advice, I think i'm going for yellow advice :)

I want to change the resonated pipe for lesser restriction, hence giving louder noise :)

Just looking for Sound gain and not worrying about power gain :P

Thanks,
Cheers.

Also, the intake manifold is the most restrictive part of our engines. Modding that will give you a few ponies. All i need now is a spare manifold to experiment on!!

That's true not cheap and apparently the Milltek headers lost power (don't know if they've fixed it yet). That Hardings ones are good and gave ~5-7 awks across the entire range as seen on my before/after dyno, so maybe that's why they are expensive - the R&D that went into them to make sure they work. If anything they would do more than the retunes out there as most mods are basically throttle control which doesn't equate to much but nicer to drive.

I'd still do a lot of other mods first and labor costs of headers is a lot and prob wouldn't bother again unless i'd done everything else (which i had pretty much). These cars wont be rockets so may as well enjoy them for the sound and for what they are.

Milltek, Arqray or Supersprint would be good cat backs for the price.

AGREE x10000000. Looking at the intake manifold *FacePAlm* . Sooo stupidly restricted.

Thinking of that too after exhaust :)

i called up VW spare parts and a new intake manifold was $1650. if i can do what i want to do with it, it will be a cheap mod for the gains!!

A good cat back can give you gains as well as sound. An MKV R32 with BMC CDA dynoed was around 137.8KW/291.6Nm ATW and my MKV R32 dynoed with Modshack CAI(similar to BMC CDA) with Supersprint Resonated was 142.5KW/310.4Nm ATW.

The supersprint will be replaced by Capristo this week but be careful with replacing the muffler with a straight pipe. It might get droney. I had my SS with just a straight pipe and the sound it emits was symphony but cruising, you start to feel the drone in your ear drums. I had to get the SS resonator for sanity.

What's your thought on this set up Big T HPA (http://www.hpamotorsports.com/cvp.htm)

Hi Jig do you know if there is much difference to the numbers as far as RES vs NON RES? Your figures seemed quite good from just an intake/exhaust, as the standard MKV R32 is meant to be about 125-130kw.

With the headers, Milltek Res & BMC CDA I got 149kw max (average was 146kw out of three runs). Not too bad but cams and intake manifold would be nice to complete the NA tuning.

From what i have read on the hpa cvp intake, its a big POS!!! No gains at all and lost power lol. Big rip off really. Only utilises short runner. Ideally you want to have both the short and long runners.

Hi G-rig: no power difference at all between straight pipe and resonator.

I've deleted the stock resonator on so many cars now. Go to your fave exhaust shop on afternoon just before they shut, whack the car up on a hoist, cut off the old resonator and weld in a straight pipe. $50 you're done and you will get more sound, no doubt about it. If you're truly worried get them to cut out the resonator and put flanges on either ends of it, then cut up a straight pipe and also put flanges on that. Now you can easily swap out the old resonator and straight pipe whenever you want to.

I think R32 with no resonated sound too loud :(.

bert on mkv has one, be interesting to get his thoughts.

Personally I wouldn't bother with any power mods on the R32, just intake/exhaust for sound. A smart man said this once (Jig) and for the price i wouldnt bother again as the gains aren't enough and don't blow you away like with turbo cars.

I had a resonator made up that you could add to the non res setups to take off a few dB (~3). A lot of non res has drone points but would be better than doing a res delete on an exhaust (like stock) that isnt designed for it.

[Jig]

There is a blue MKV R32 on youtube with the resonator deleted and it sounds like pop corn popping in a microwave rather than the real rasp. By all means try it out but I am fairly sure it will yield disappointing results. But this is just my opinion.

> Your right there G-rig. There are after market exhausts that has been specially designed to have either a resonator or a straight pipe but removing the resonator on a stock exhaust which was not originally designed for a straight pipe might be unfavourable.

>> That is right G-Rig. Like you said, if I wanted to stick to an NA setup on the R32, intake and exhaust are probably the 2 most obvious mods. I wont even consider ECU tune for NAs. The headers on the R32 is pretty good which is why there are aftermarket headers that cause loss of power on our cars. I would rather spend the money on suspension. Tuning an R32 though for FI takes it to another level.

[Pharkus]

In my simple way of understanding what I have read (this is not much technically), NA cars do not have as much potential for engine tuning as a FI car like the GTI. IF I ever have the budget I would go down the handling (suspension, wheels) route before touching anything in the engine bay.

Also, for my own personal use, I would also consider an audio upgrade as well. You can only go so fast legally on the roads, but you can pump your music up as loud as you like!

[windyzz]

Yeah N/A car won't get any way close to Turbo car in term of tuning potential and Bang for BUKS.

But Sound wise :D :D :D. Must be done :)

[Justin Fox]

I agree that simply deleting a resonator is a ghetto mod, best left for cheaper cars than the mighty R32! An exhaust system for the R32 can't be cheap though right? The OP's post seemed to suggest he had a small budget for this and deleting a resonator costs $50 :lol: that's got to be affordable!

windyzz, perhaps let everyone in on exactly what your budget is, that way these guys who have already done and bit of this, and that might be able to help you out a little more. :)

[Jig]

I had a look at the original post by Windyzz and cheap budget and header modifications dont go hand in hand. So Justin's comments about letting us know how much you want to spend might narrow down what is a good modification for the MKV R32 whilst remaining NA. I will go one step further and quickly document the NA mods for the MKV R32 and the rough price schedule. Please note, none of the below includes labour charges.

1. Cold Air Intake - ranges between 300 - 1000.00
- Modshack VTDA - 350.00
- BMC CDA - 600.00
- GruppeM - 900.00
- VF engineering also has one but not sure how much that is

2. Cat Back Exhausts
- Supersprint Resonator - 3K
- Supersprint non-Rs - under 3K
- Milltek - under 3K
- Capristo - 6K ish
- Kriesegg - 6Kish

Hi Justin,

ideally i don't want to spend more then 500 buks :P, I'm just looking for sound gain(but not too loud - somewhere between resonated and non-res stock) .

I'm not really after performance gain. I might go to a exhaust store and get it done this weekend. But I'm not 100% sure lol

Thanks

It's affordable to get a fart can sounds (as Jig put it albeit a bit more tactfully).

1). Euro cars aren't cheap to buy, 2). Neither is modding them, 3). Neither is modding N/A cars so us lucky R32 owners have the trifecta!

I don't think 500$ will get you much of an exhaust windyzz, possibly get a different centre resonator that gives you a bit more noise than the stock one but is still a gamble IMO.

Yup looking to replace my resonator with an aftermarket/custom one

[G-rig]

You would still need a traditional style one muffler IMO, a hot dog on the standard exhaust woudln't be enough (but would be for a track beater where drone doesn't matter).

You reckon replacing to custom hot dog(resonator) wis not enough ?

Thought it will give a louder sound without giving too much drone because i'm not replacing it with straight pipe. But i dont know :(

[G-rig]

Hey mate, i had a resonator made up for Mictch (Longwall) 's car which helped but that was for a non res Milltek exhaust not a stock setup.

[windyzz]

I called one of the local exhaust shops around my area, and they advice that replacing a hotdog resonator from a stock resonator will not make any different (in term of loudness), however they advice me to delete the resonator(middle) instead.
Cost $60.

[G-rig]

You may have to experiment.

[Big Yellow]

Yeah only way to find out is to try!!

[ar44]

I noticed in the first post the 'flapper mod'. Is this purely disconnecting the vacuum line to the flap, so as its permanently stuck open? I imagine its been discussed to death, but how does go?

It flaps alot more hehe, nah but IMO it sounds better.

[mikinoz]

So people, I know Diesel is not sexy - but it is the new Green and we will mod them to make them a bit more Brown.

Rear muffler removal 103KW TDI - results in faster spool and slightly lower exhaust tone (no drone).
