Smallest exhaust size under 300hp
Hey peoples,I did a search but couldnt find anything.I was just wondering if i could keep my greddy piping on my dohc vtec soon to be boosted or if i need to get something bigger for the turbo application.The greddy piping is rather large but to be on the safe side id say its 2 1/4. My friends tell me to to swap it out in favor of str8 3inch piping, but im on a budget here.Would the 2 1/4 be ok?If any how much performance would i lose?

Re:Smallest exhaust size under 300hp
i had 2 1/4 stock exhaust and had a 2 1/2" mandrel bent exhaust installed. i have a straight through fart can style muffler and no catalytic. my car was boosted before and after the 2 1/2" exh. there was a slight difference with the 2 1/2"exh. the turbo spools up to full boost 10psi in 2nd gear 300rpms sooner. but if you have to run the 2 1/4" exh like i did for a couple of months, then there's nothing wrong running it like that, you will feel a difference with the bigger exhaust but it will be minimal. and 2 1/2"exh is good til 500whp. i'm not making this up it's in this link, under exhaust:

Re:Smallest exhaust size under 300hp
just go with 3" if you can in the future... alot of people might say its too big but im calling bullshit....
i had a true ID 3" thermal r&d exhuast on my all motor b16 with bolt ons.... stock internals....
even with a shity small intake, and a shitty greddy header i was still pulling 94-95mph traps in my eg....
top end ripped hard for a b16....
