My friend has one in his 96 jimmy, not super noticeable at an idle. slightly above stock noise. Its once you start revving around 3000-4000 rpms that it seems to wrap a lot and is pretty loud, sounds really good. As for interior noise, it has a drone. Its not too loud, and if you are playing music you wouldnt even notice. You get accustomed to it after a day or two.

I like the dynomax super turbo, sounds more like a v8 and not a fast and furious car

I get some cabin noise with my 40 series but not bad. It sounds really good with the 40 series i think, i have a high flow cat also but that doesn't make a big difference. I also have 3" pipe from the cat back which does make all the difference... If you leave the stock pipe in there it sounds a lot higher pitched and raspy. IMO not good... 3" pipe makes a lot deeper sound.

Sounds like a timing issue but you wont get any help posting that question on someone else's thread.

Instead make a thread here: 2nd Gen S-series (1995-2005) Tech - Blazer Forum - Chevy Blazer Forums With thread tools under the page numbers on the top right of the page
