what size muffler, 3.7

I am looking to possibly get a new muffler to go with my k&n cai, but I don't know the dimensions. Like inlet/outlet size/position, length or any of that info would be helpful, ty all!

Re: what size muffler, 3.7

lot of threads on this already. are you looking for loud or not?

size is 2.5 stock. center to center outlet. the shorter the length the louder the exhaust will be

Re: what size muffler, 3.7

Yeah, I read up on the posts, I just wondered the specs so I could order from summit racing. So inlet and outlet are 2.5"? I thought it was center inlet and offset outlet... you saying its center for both inlet and outlet? Thanks friend

Re: what size muffler, 3.7

Yeah, I will pry do that tomorrow. I'm at work and drove my truck, plus we've had record rainfall and I'd have to get my scuba gear lately to crawl under it... lol

Re: what size muffler, 3.7

2.5 inlet, SUPER 44 FlowMaster. then dump it. dont worry about inlet/outlet position if you dump. (dumping within the passenger cabin is illegal...)

Re: what size muffler, 3.7

my choice here would be to get a Magnflow catback system They're around $550-$650 depending where you can find them.
