I see that that BMW now has a line of performance parts. They are selling what they call a performance muffler. I am wondering if anybody out there has seen or heard this muffler. I have seen some postings on other web pages that they are no good or too quiet. I was wonder if anybody has had any experience with the muffler. My questions are ? Is it louder than stock ? Or is it as loud as a Supersprint muffler ? What are the tail pipes made out of? any info would be highly appreciated. Vic
I bought 1 for my 2003 330i zhp...and didnt gain but 2 hp and torque. However the sound is wonderful. Idling is a low growl. When I punch it, well, lets just say a refined powerful growl that makes my seem a beast. You will NOT gain much performance but sound is great. If you want performance, go with Dinan, nothing else. Secondly the price is too much.
