Flowmaster 40 Series Delta Flow Mufflers Reviews


Flowmaster

Reviewed By Linda O (Mahwah, NJ) Reviewed for a 1999 BMW 5-Series —2/7/2011 3:04 PM

This muffler is great, dont get me wrong but the representatives did not know a thing about my car, although the said they did. I sent back and order a new muffler that they recomeneded two times before i had the right one. The car sounds great and has a very deep tone to it. Not too ricey at all which is what i was looking for. It has the loudest tone to it at about 2000-2500 rpms. The muffler was extremly hard to install and remember to get it bigger or smaller than the pipe on your car so that it may slide on or in and make it easier to weld. I am decentlt happy the way it turned out. (3.5 out of 5 stars)

I installed this by removing everything from the stock muffler back. Installed the series 40 exactly where the original muffler was and had exit pipe turn out just in front of the rear tire. Unless you were in the throttle really hard, you couldnt tell if it was a V8 or the V6.
