I'm trying to decide what size muffler or resonator I should get, but it is obviously going to be location dependent. I want to put it right after the dp, but I'm not sure what will fit. I'll have to use two if I put it after the rear end, so I want to avoid this. I want one muffler before it splits into duel exhaust. I also want the largest size possible to make it as quiet as possible.

performance peddler seems to be the place to buy.

 

Dual exhaust is just excess weight. Run a 2.5" or 3" metal core high-flow cat and one of the normally recommended mufflers from parts peddler and you will be fine. I run a 3" cat and 3" stainless exhaust out the back of the car, and it is far quieter than my 300ZXTTs that had mufflers but no cats.

 

 

where did you get your high flow cat? You recommended one in a post i looked at yesterday, but I looked through so may posts on exhausts and mufflers that I'd be hard preessed to find the thread I want.

Straight through dynomax or magnaflow seems to be the ticket for the muffler. I'm just unsure of diameter.

 

my cat is a magnaflow one that Jason @ Enthuza whipped up for me.
