77541 INSYNERATOR High Performance Muffler

Bought this muffler for my 1998 F150 . Muffler quality and build is just like the Flowmaster 50 series. Muffler gives my truck a bit of a growl but not too loud or annoying. I also like how the inlet and outlet actually fit snug on the pipe. I bought an extension pipe and crack and joint exhaust seal and clamped mine in. No exhaust leaks and the truck sounds great. I would definitely buy another.

Well made , and sounds good

I replaced the Magna-flow muffler on my 06 Chevy truck. Part fit was perfect, and install was a breeze. Good value as well.

these did not produce the sound that I was looking for.

Sounds pretty beast on a 4.2 V8 Audi. Quality feel not as cheap feeling as the cheap thrush mufflers.

Great muffler. I installed it on a 97 f150 and it sounds very good. Not too loud and not too quiet

Very good quality piece for the price!Looks,feels,and sounds just like the old 40 series flowmaster.

very pleased, great quality excellent sound
