whats better... aftermarket o2 or stocker ported to hell and back?

 

a 02 dump forsure

 

i got mine from map performance and its awesome

 

aftermarket........ported!

 

after market!!

 

ok and what about the manifold? can I just get the stock one ported? I was going to let bob from MAP port the o2 + mani, but I'll get a aftermarket o2 after reading this thread.

 

i would go to PPI and have their extreme porting done..ive seen it and it looks like alot of porting they do..

 

invidia o2.

dont waste your time porting a stocker, as the i.d. feeding the d.p. will never come close to aftermarkets.

 

Thanks, I appreciate the feedback everyone. now onto the exhaust manifold.... stock and ported or aftermarket? From my experience, the stock manifold can be ported pretty good, but ill leave it up to you guys to make my final decision.

Thanks again

 

ported stock exh mani.

 

Definitely ported exh mani. Best bang for your $. Unless you are Mr. Moneybags, then get a Shearer Mani.
