Nice system overall
Always love Flowmasters and have had them on our family%X92s trucks for years. Flowmaster sales and customer support folks are absolutely the best! Really nice system and pretty dang easy to install with simple tools. Make sure you have a breaker back and a deep 15mm socket for the install. Feedback: The exhaust tips wouldn%X92t tighten enough, so have to tack them probably. Clamps have to be adjusted to the right position or you have small exhaust leaks which is slightly tedious.
Cat-Back Stainless Split Rear Exhaust 2017 GMC Sierra 1500
Good looking system & easy to install with right tools & equipment. Sounds good too, nice rumble without being obnoxiously loud. 2 gripes: 1- The front of the headpipe is not flared quite enough so it is a bit of a problem to get a proper seal when clamping it back at the ball flange using the stock clamp. 2- The 2 exit pipes were difficult to clamp. Stripped thread on clamp when tried 1st time. Had to set clamp bottom part to overlap joint so that Tailpipe and Exit was grabbed simultaneously.
