I got the Borla installed, but I want to free up up more HP, what else after the borla do i need to replace to go all the way to the motor?

BTW the Borla is very quiet, possibly same as stock, lost the 350z drown though....

 

get some headers...(pricey install)......and test pipes....and damn...well ull have a load more hp......and the sound will be much much louder....and probably raspy if u dont get resonators in the test pipes

 

plenum
intake
greddy evo exhaust lol jk
cams

 

I just did the Borla as well, get those cats off.... go with high flow or test pipes and headers, a crank pulley, and intake. The car will wake up nice.... plus you'll save some weight by tossing those dumbells, I mean cats....

 

Oh yeah, the Borla is loud you just can't hear it due to those stock headers and dumbells.

 

Yep

Dump the cats, and put on Crawford Hi-Flows.

Thx guys

 

if you want even louder, get a muffler shop to cut off the borla's pre-mufflers. i'm thinking about doing it.
