SonicMS, the shop I work at did it for me. Fit pretty easily, wasn't any harder than a 335i. A little close between the two DPs but everything fit very nice and accurate!

Hi!

Is there any significant change in the sound?

I still have no time to get my DPs installed.

Coupled with the Milltek, its loud when you push it but sounds nearly stock when your just going around town. I haven't driven it with just the downpipes, got it installed together.

The sound when shift 1-2 & 2-3 is addictive.

Question for u all, how is the Down pipes.

Also, if u change the dp but don't change the exhaust does that limit or negate the benefits since it is back pressure?

No, most of the gains are had from catless downpipes.

what Kai is saying, I think, is that the catless DPs provide a significant performance increase compared to performance exhaust, i.e. you are better off buying the DPs at $1k versus $3k+ exhaust
