Which exhaust is better for autocross?

[DSMRomEo]

I'm undecided on which exhaust system I should purchase. I can't decide between the Buschur 2.5"SS or the Apexi N1. I don't plan on going bigger than a ported 16g So i'm thinkin' I shouldn't go above 2.5", but i've heard bad things about Buschur, but i'm still not ruling it out. I'm on kind of a budget right now. Thanks for your time

Get which one you like (There are other exhausts that are cheaper, aren't as attractive but flow like a MOFO!), or MYO, or have one made. With a turbo car BIGGER is BETTER!

Anyone out there with the Buschur? Any problems ie: rattling, cheap welds, rice sound.. also any pics with it installed??

I used to feel the same way until the boost creep started. Never going bigger than a 16g? 2.5 or 2.75 would probably be best. Just my opinion...*prepares flame suit*....

I knew about the boost creep, and i've read that having the Wastegate(actuator) porter than the lessens the chance of creep... I may be wrong, but I know in some cases bigger isn't always better

I have a ported 16g with a hogged out O2 housing and a 34mm flapper. With my 3in exhaust, I creep from 15psi to 22 psi.
