Exhaust systems

[99gti]

I have a 3" Stainless dump into a high flow cat (can't remember brand). That set me back about $750. From there it goes into a Remus system that I got seond hand for $250. So for a full system you would be expecting around the 1k mark.

Has anyone replaced a system on a GTI from the Turbo back? I am looking at doing that in the future to free up the turbo abit and any brands or reccomendations would also be helpful!

I got a 3 inch turbo back system for my A3 which was 1600 IIRC. I knew I was going to get a big turbo in the future. I would probably go with 2.75 inch if you are keeping the std turbo but considering a chip in the future.

The DP definitely helps with spool up.

Yer ide pay that.
And Dont worry there is no way ide ever put a "ricer" (skyline) exhaust on my car. Will Definitly be a 2.5" cat back with a duel tip muffler

Thanks

On a 2L 8V, i'd be going a 2.25" else is overkill, probably ruin bottom end.

Will cost you anywhere from $500 to $3k. I would budget min $1000, max $1500. I paid ~$1400 for a Milltek cat-back for my Bora 4motion, but I got an awesome price on shipping direct from Milltek as I was being stuffed around by the supplier in the UK.

what kind of power gains did u get out of the bora?

looking to get this doen to my v5 bora

Mine isn't too quick either, but it'll be even worse if you put a massive exhaust on it.

Mate, I've got the whole stock 2.25 inch system from my GTI here in my garage, no good to me anymore if you want it, it's yours, you can use all the piping, cat, muffler, etc. or put your own choice of muffler on, if you want to arrange to get it picked up you can have it.

Nothing wrong with any of it except where it was cut near where it crossed over the rear crossmember to make it easier to get off the car, just needs re-welding at that point. The down-pipe is obviously no good to you but the rest might help you out.

I didn't realise the stock exhaust was 2.25"!!!! Assumed it was a 2" Thanks for that.

Highflow cat, deleting the resonator, and a new rear muffler it is then!!!

[stevend01]

Thanks steve

Just FYI update: got quoted about $250 mark for a high flow cat installed (X-force ceramic cat), price goes up to $400 for a metal cat installed. Mufflers start at $150 i think he said.

Gonna go in and get a quote for cat, muffler, and deleting center resonator some time soon, and post up price, incase anybody else wants the same to their car.

[D3bb4]

Does anybody know how good the stock cat's are?

Highflow cats seem to not be too cheap installed, so trying to figure out if it's worth the $$$.

Castle hill exhaust quoted me $280 for a ceramic high flow cat installed, Vs. $330 for a metal one - the metal one being a higher flowing type, and said to last forever. (also quoted an x-force muffler installed at $260, or would fit provided muffler from $120)

I don't believe the stock cat is a restriction. I haven't seen any specific tests done on Golf's, but I believe that is the general consensus.

When I had my exhaust fitted last weekend, they had an EVO VIII Lancer there, full rally spec with a straight through exhaust, which the guy was saying was dyno'd a couple of weeks ago. With new emissions requirements they had to fit a cat up to it and apparently it made no difference on the dyno at all.

Steve here's a pic of the system.

That muffler is so ugly!!!!

Muffler and deleted resonator seems to be a must now
