Flowmaster Super 44 Series Mufflers Reviews


super 44 series

Reviewed By Abel M (Santa Ana, CA) Reviewed for a 1993 GMC Sonoma —11/4/2008 10:21 PM

I drive a 93 GMC sonoma with a small 2.8 six cilinder engine in it. A tiny engine indeed but equiped with 44's i promis you its louder than the average V8. WHen i hop on the feeway i dont step on the gass as much as i use to in order to reach 65 /70 mph so a slight increas in power wass also noticed. THe only down side of this muffler is that you wont be able to sneek your girlfriend out of her house late at night anymore. Evey single car alarm goes off in small neighborhoods. In conclusion, loud interior and loud outside.

Flowmaster Original 40 Series Mufflers Reviews


2016 GMC Sierra

Reviewed By Chris N (Las Cruces, NM) Reviewed for a 2016 GMC Sierra —6/13/2018 7:53 AM

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.
