My Euro 'Build' Thread

yeh but his revs were bouncing stuffs up his throttle response similiar to what i had.

not sure now.
aaron i envy your stock car pulling 110kw stock damn... :p

I can't imagine a leak giving you more power... it might be more air but that air has massive turbulence and it's going to affect the rest of the air coming through the TB.

I'm getting my exhaust redone next week, having the same 2.5" section from the cat, then a split into 2 x 2" going through 2 of the Berklee Race mufflers. It will flow way better and should give me more power at every rpm and a decent jump in the top end as well. I just hope it's not any louder!

just curious..so your saying a dual exhaust flows better than a single? I thought a single outlet would flow better?

A single outlet would flow better, but it would be unbearable. My exhaust right now is 2.5" b-pipe with one tiny resonator, going into a 2" race muffler. That effectively makes the total size of my exhaust 2", which is a smaller than the stock one. With an exhaust your smallest point is ,realistically, the size of your exhaust.

If I keep my 2.5" section from the cat, then split into 2 x 2", then the smallest part is still only 2.5". Then if I run the 2 x 2" sections into 2" mufflers the smallest part is still only 2.5". Theoretically my catback now actually flows less than the stock one with a lot more noise :p

The best exhaust setup would be my catback through a 2.5" muffler, but if you drive mine now and hear how loud it is with just a 2"... you'd realise why I'd never get a muffler that big. Splitting the gas into 2 pipes then running it through 2 mufflers SHOULD make the car quieter and also flow a lot better. I've spoken to Haks and he was saying the split has minimal effect on flow.

Right now on your single outlet, is it still a 90 degrees bend?

If it is, then there really isn't a benefit of having a single outlet than stock except maybe reducing abit of weight.
