Flowmaster Y-Pipe review

Reviewed By michael s (point pleasant, NJ) Reviewed for a 1988 GMC S15 Pickup —10/25/2017 5:02 AM

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.

Not too shabby

Reviewed By Zackary A (BINGHAMTON, NY) Reviewed for a 2015 GMC Sierra —4/14/2017 8:19 PM

Too quiet with just the muffler . Had to cut out the resonator. Sounds pretty throaty now probably perfect for a lot of people .
