A restrictive OEM cat seems more... well, restrictive than a crushed, twisted curvy pipe with no cat.

Overpipe seems like the last piece to upgrade for the exhaust. Although the bends and piping diameter seem restrictive, the headers and front pipe will be 2 biggest gains for exhaust, and then catback and overpipe. I'd do headers before overpipe, or get the PPE headers and do both!

Hey, the cat back has a mid sized resonator on it and the test pipe does not have a cat and not resonated. The canisters and test pipe have helmhotz canisters on there so drone is minimal and almost to zero. In terms of rasp there is none at all! The exhaust sounds perfect and is the best I've ever heard! Oh and no cel. I still have then primary on the stock exhaust manifold. Hope this helps.

Go with Motiv, can't go wrong there. Love my testpipe and waiting on their catback!

I heard whispers of an intake manifold too O_____O

Thanks man! I think I might go with either a resonated front pipe or the ARK one which has
a hemholtz in it.

test pipe wise the helmholtz is the ark route and trust me that exhaust system sounds FUCKING AMAZING.

Nameless also has a one piece OP/FP with the option of cat and hemholtz
