good muffler? - BMW Forum

MiguelACA · 09-29-2006, 04:56 PM

hey guys, ive been wanting to get a catback exhaust for a while now, but cant get myself to spend over 500 bucks for one, so my question is what would be a good muffler to get, just the muffler, something with a nice deep sound, nothing rice, performance doesnt really matter as long as it doesnt decrease it, just something that sounds nice

Borla

i searched the borla website, but they dont have anything for my car, unless i get like a universal one?

Nothing will be a direct replacement. You have to go universal unless you go catback.

I like flowmaster, the couple e30's I've heard with them sounded awesome, I'm sure a m50 would sound just as cool.

I like a burbly gurggly agressive yet understated tone, and thats what those mufflers seem to give these inline 6's. Just get a small diameter piped one, not a 3" pipe one. Get like 2.25" in/out muffler.. anything larger unless you are turboed will make it sound rice.. its all about resonance, and if you get too large of a diameter the exhaust pulses space out too much and you get the fart can effect.

Flowmasters sound good but don't flow well. My friend gaind 2 wheel HP when he put a flowmaster on his Z28. When he opened the cutout in the intermediate pipe he gaind 17 wheel HP. So I recomend something that is a straight through flow like a Borla, Magnaflow or Dynomax.

It will come down to your budget. Borla makes a really nice product but you will pay for that quality. Magnaflow makes a good product too but it isn't on the same level as the Borla.

the main problem you will encounter is that borla only has a single inlet muffler..but thats easily solved because they make a 3" inlet muffler

just have to weld a merge which is no big deal and you wont lose any power if its done right

Magnaflow.

Borla's a great brand. But there are a lot of tuners out there that design exhausts specifically for our cars. A great is example can be found HERE.

ActiveAutowerke is a great company that have many years of BMW tuning under their belt. I haven't purchased an exhaust from them, but have bought many components, and they are first rate. The link above provides dyno info, and video clips to give you an idea of the sound obtained.

A few bucks over your budget, but it would be well worth it.

right but thats a single pipe exhaust system being that you have a 318...he is talking about a 325i which is dual all the way back, not so cheap to have made custom cat back...
