2012 GMC Sierra
Flowmaster 40 Series Delta Flow Mufflers
Love it
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. View more reviews...

Flowmaster Y-Pipe
Flowmaster Y-Pipe review
This piece is made of a heavy steel that' going to last seemingly forever. It has great flow characteristics and fit my needs perfectly. Flowmaster products are "top shelf" quality. View more reviews...
