G6 GTi Exhaust advice

Post by Shaff »

Hoping someone who has previous experience with this can assist

After going K04 i would like to upgrade my exhaust

Here are my options

76mm thru out with 1 box in the centre

Cut off the muffler and Y pipe it?

Next recommended by Powerflow (they say have good experience with this exhaust)

Cut off after resonator with split to 50mm or 63mm Y pipe with 2 small boxes before tailpipes

Ive read up that 76mm is overkill for the power im making and its just a waste?

So any boys here who has been thru this please advise and if you can quote what power you gained with you upgrade

It is true that 76mm is overkill but for the price difference and if you have the space there's no harm going 76mm , I would recommend that the downpipe is 76mm for heat and performance Reasons , rest of exhaust doesn't matter and gain is small.

The one box setup Will be louder and the 2 box at the end Will be deeper

it's your preference at the end of the day , some can live with no boxes on their daily's that makes loud over run pops and bangs

What you think of those should i do it or should i get 1 upgraded back box instead

Hey,

I also drive a 6C GTi, where did you fit your down pipe and is your car a lot louder after the down pipe?

The reason for a bigger DP is to lower the exhaust gas temps , by getting the hot air faster away from the turbo , it allows the tuner more room to tune for more power while retaining reliability at the same time, it will make a small difference in sound over stock DP when not tuned, but once tuned , you'll hear all kinds of awesome turbo noises hence why the DP goes hand in hand when a car is tuned but it does not really make your actual exhaust note louder, the amount/type/placement of exhaust boxes will determine how loud or silent the exhaust note is.

Thanks for this, is it worthwhile to go for a cat-less down pipe or not really?

So this is the current setup i have the Dzv milled in on the turbo housing

So i thought when i go K04 ill get awesome turbo noises but its still the same maybe a little louder i can here the turbo spooling lekker but not dumping the way i want it

Is it because i have a closed air intake, i do have the latest revision DV on

The DV milled onto the housing will cause it to be much quieter than a relocated K04, coupled with a closed intake you might find it difficult making "tsu tsu tsu" noises. In terms of exhaust, 76mm DP and 76mm till the Y followed by 63mm piping is more than sufficient - speak to a knowledgeable exhaust shop like TMSS mentioned earlier - Please don't go to these IG famous noise boys who like pops and bangs
