Flowmaster 40 Series Delta Flow Mufflers Reviews

Love it

Reviewed By Ray R (WESTERVILLE, OH) Reviewed for a 2011 GMC Sierra —7/2/2013 10:48 AM

I had a local shop cut the stock muffler on my 2011 GMC Sierra and had this installed. I paid 70 to have it welded on the stock exhaust pipe and could not be happier. if you have my truck you will need the 3" center inlet with 3" offset outlet. There is some resonance inside the cab but nothing crazy that will disturb your conversation or phone calls. could not be happier with the delta flow.

Flowmaster Split Oval Exhaust Tips Reviews

They make the car look great.

Reviewed By Daniel S (ORANGE, CA) Reviewed for a 2015 Volkswagen Jetta —6/21/2015 7:44 PM

The tips are easy to weld on and are just different enough to make people notice them.
