exhuast size question
I'm going in next weekend to get a quote to put in a custom exhaust(and also check my brake rotors, see if I need to change, if so I'm gettin A8 front rotors). My plans for the future will be either K04, gt2x, gtrs elim, and no bigger then that!!!
Should I get a 2.75 inch exhaust, or is it still better to go a full 3 inches? Turbo back or catback? (I know turbo is better, but is catback good enough, I'm not looking for a 1/4 rocket, just a faster daily driver)
Would it be better to buy a muffler and cat then just get the shop to do the piping, or would I get a better deal ordering muffler and cat through the same shop I get my custom piping done?
Thanks

RE: exhuast size question
2.75 will be big enough for your plans. No reason to go bigger unless you want it louder. You want a full turboback. The cat section and dp is the most important area to change, so skipping that is bad. If possible, get that stuff 3" and 2.75" the rest of the way back.
As for parts, have them increase the inlet/outlet of the stock cat and add in a borla or magnaflow strait thourough muffler. It would be cheaper if you get it yourself, but less hassle if you dont. ALso if you want it quieter and more tame on the highway, i would also get a resinator

Only thing against 2.75" is the piping is harder to come by.

If 3" is easier and cheaper it sounds good to me. So long as I can find a classy muffler that is REALLY REALLY quiet but doesn't impact performance 2 much. (quietest not restrictive muffler???)
dha514, I can't go catless, I'm limited here in Vancouver, B.C. for that. It's not as tough as Califonia, but we have emissions testing and can be pulled over for a loud exhuast, etc.
Exhaust, brakes, cheapo intake, fmic and ebc are on the list of hopeful "soon todo's".

Since you will be running a cat, it will be quieter, but you will need to run a resinator and a large muffler (still strait through) for it to work its best. Chambered mufflers do not belong on a turbo car.

APR designed their exhaust to work with all thier products, which I have, and they only use 2.5" tubing on their B5 exhaust system.
I have their;
APR stage III kit
APR high flow cat and
APR cat back exhaust
It works, sounds and performs great, without being to loud. As a matter of fact, APR has a reputation for being one of the more quiter exhausts on the market. I'm no trying to sell you an APR exhaust but just to inform you that bigger is not always better and that 2.5 would work just fine, depending on your needs. Mike Hood only runs a 3" exhaust and is putting down 600whp, so you don't want to put yourself in a position where you are not moving enough air to justify a 3" exhaust as it can hurt your performance as well.
