anything cheap. straight through is good.Sounds promising, can you recommend any sort of muffler?
Should I even bother with an ebay special? If they even sell them on there
stay away from 3" exhausts on a standart d22 because you will lose power rather than gain some. you always need some backpressure so stay 2.5" like stock no matter what. a turbo back 2.5" would be the best but not the worth the money in my opinion, on stock always!
Absolute BS--do you have facts to back that statement or or just internet chat I have the facts which are backed up by a dyno..before and after A 3" system with a muffler and hot dog produced as much as my DP chip..both 10% each.
Agree 100% Gazza. Must be a Internet Warrior...
A exhaust alone add's 10% hp
Without taking into account for a DP chip!!!
This is fact not fiction......

back pressure yes, i dont know what kind of emission standarts you get in Au, but all d22 up here must have a catalyst converter fitted, everyone i know who tried to go bigger exhaust size ended up going slower also. 2.5 engine
You don't need any more back pressure than a log style exhaust manifold and Turbo charger hanging off the engine. As stated in my previous post that is the exhaust system anything after is just the means of getting rid of the spent gasses from under the bonnet. No back pressure from there required. If you think it does I like to know how and why.
On a say a Toyota 1 HZ engine (naturally aspirated), yes going to a 3 inch over 2.5 will actually have a decrease on output.
Just put a muffler INTO my 3" system
Car runs 150% better! hold gears properly and down on fuel!
