An exhaust question for 318is owners!

[Gonzo318is]

I'm pretty sure I'm going to go with the dynomax, just not sure which muffler to go with the ultra flow or the super turbo?

[hamann318is]

I got the super turbo. 2.25 offset inlet and offset outlet. They didn't have to do any custom fabbing really to make it fit. Just a pipe from the stock exhuast to the muffler, and a tip out.

Nice, how much did it cost you? Did they use a hanger or does it rattle?

40 for the muffler from www.summitracing.com. 35 installed with a tip. They welded some hook type hangers that hang the exhuast from the hooks on the car's body. There's one the side and one on the front of the muffler. I have never heard it rattle, but it does hang a bit lower than stock. I'm sure the hang can be fixed, I just didn't care enough to (I think it looks fine).

I went with the magna flow muffler... a little more money $80 + $60 installed but well worth it compared to what a cat back sys. would cost! ;)

on my 318is i had a custom magnaflow 2.5 inch (i think) system from the headers back that the PO put on... he said a local muffler shop charged him like 400 for the whole thing.. it sounded pretty good, not obnoxious in traffic but burly when you're on it... might be a cheaper route to experiment with

2.5" or 2.25" inlet on the Magnaflow muffler?

2.25, I think.

Yeah, that's what mine is.

You can't go wrong with a Magnaflow for the money.

BTW, don't expect V8 sound from a m42.





You'll have to modify your valance a bit though.

Mines far from V-8, but there's no fart cannon noise. Just bassy I-4 sounds. ;)

Same here, I dig it.

Oxymoron. :P
