I have a ported motor with an Apexi intake, boost controller, HKS turbo timer, Greddy intercooler, 3" downpipe, and stock exhaust to an Apexi tip. My air pump has been removed so my cat is getting clogged. What exhaust should I get with no air pump? Should I go with a high flow cat, with a 3" exhaust to a random tip, or should I go with no cat since I don't have an air pump, or should I go with something else?



Thanks for the help.

 

I've got a 3-inch straight with N1 dual tip. Does good. (The 3 inch straight replaced the cat, not cat and dp.)

 

If by tip you mean literally a tip...then I've got the full muffler.

 

no i have apexi exhaust tip i guess, its nice, but my cat is getting clogged and need to find the solution soooooon. thanks man

 

Mine was from rx7.com. Easy fitment, good quality.

Mmmmm, resonated...I had a resonated MP combined with my Racing Beat Dual Tip and it was nice and quiet but opened up nice and loud at WOT.



I love the racing beat because it looks stock, yet you can squeeze over 400rwhp through it.
