I had a local muffler shop complete the install of my Flowmaster super 44. Great fit and super sound. My truck is looking sharp and sounding even better. Thank you and will be back for my other truck.

Nice system, sound is very nice without being overpowering! Easy install, only issue I had with it was the bolts for the chrome tips either were to soft or needed washers! I broke one of them before it snugged on tail pipe. I got the hardest SS bolts,nuts,& washers from the local ACE store & that worked out well! Would have been 5 star if not for that issue.

System fit well but for the cost it should of included a new clamp for the ball fitting and the clamps on the tips are a joke no way they would hold the tips in place I had to go get new clamps for them for the price you would expect better quality than spot welded tin clamps that brake off with very little pressure.

Better quality than I thought it was going to be. Took longer to install than it should have (broken nuts at cat) rest was pretty good! Tip bolt snapped when tightening! Quieter than last exhaust but a nice low growl.

Sounds great, had garage install it. It says it's stainless steel but does not look like it. Clamps not the best, put a tack weld on each.
Install Time: 30-60 minutes

System was pretty well built. Sound is the deep- throaty rumble but not too loud. One piece wasn't wedged so we had to cut and weld. The clamps are nice BUT they couldn't tighten enough to lock the pipe in place so I had to tack weld pieces. Would still buy, but keep the above information in mind.
