Quad Diffuser options.

[Da_Meister_22]

Hey guys I really want to get quads on my 135i just like I did with my 530i. I know all I gotta do is get a "Quad Diffuser" but who sells these...havent been able to find anything yet.

Youll need the accompanying quad muffler axleback at least. There are plenty of options ranging from a $5k kit to a 350shipped eBay piece that fits pretty well. The exhaust piece is where youll really have a problem, unless you have a really high quality exhaust guy.

what I meant was if there's any "preferable" brands for quads here in the forums. Or any reviews from previews customers...

I've got Eisenmann. Looks good and sounds great. Got one of the cheap-o eBay diffusers though. 3d Design has a great one but it's really simple and is off the charts expensive.

Here's a thread where I posted the end result.

A little note though. No matter which quad you go with it's mostly going to vent through the drivers side unless you go all custom and have it balanced better.

How much you paid for your quad exhaust?

Do you have a sound clip?

I'm not sure how good the quality of this one is but they have a quad option in the drop-down.

Got mine new direct from them shipped for 2k. It's a bit pricy but the finish is great (hasn't tarnished or rusted with crappy NY weather) and I have no doubt it'll last a long time.

No sound clip of mine at the moment but here's a vid with the single side race exhaust from them. Mine sounds very much like this one. The quad is really the same system just with the second exit for the passenger side pipe. I also have the same polished finish and you can see it in this vid too.
