ok i have a costom made exhaust on my car right now its a B18C W/ I/H/E and a OBX intake manifold, the exhaust on it now is a 2 1/2'' straght pipe into a muffler (apex i) but i have no back pressure what so ever it runs like **** till 6k then it pulls crazy and i was wondering if i should add a cat and a resinator or go with a stock LS or GSR exhaust?? my friend has a LS and a GSR exhaust that i could get.

Thanks.

 

You can get exhaust muffler pieces that have a hinge-like circle-ish metal gate that has small holes it in. They swing open when you're at WOT or whatever, but when back pressure is needed, they close shut.

i guess but i dont wanna spend too much on trying to mess with it i have a resinator (stock) i can throw in it.

 

I'd go with putting the resonator or stock muffler on... Putting the entire stock cat-back system back on would be way to restrictive.

 

yeah thats what i was thinking too. or if i had the money id go with a stock ITR exhaust but.. but no cash
