if your looking for a bolt on cat back with dual exhaust the only two available are Magnaflow or GMPP. and since these are from the cats back, youll be ok in Ca.

Hey guys I've been looking at a few different post and I'm gonna redo my exhaust system. From what I have read I'm thinking of running a 2.5 or 3 inch pipe from the front then adding a Y at the back and run two 40 series magnaflows and finish with 4 inch round tips..my question is what do people use to replace the resonator? I seen one post that says they used a 4 inch flow through,but what is that? A flow through resonator or a flow through muffler?? I'm planing on ordering through summit racing so if someone had a part number that would be great.

Thanks guys

Any 4" flow through muffler will work.

I'd go 2.5" back myself.

4" tips are perfect!

Do a search on ebay for:

4" round muffler 2.5" in

and it will kick up what you need. Just make sure it says its a flow thru
or that the core is 2.5".

This is a nice one:

Crab Intakes CAB, MPD Ram Air hood, Custom exhaust,
WAMS High Performance Tune and a whole lot more....
