Great preference mufflers
I bought these mufflers to let my truck have a nice true dual exhaust system and a great sound and they turned out to be perfect.I would recommend them to anybody.They are a nice free flowing glass pack with a nice sound and they don't take up a lot of space they tuck up under my truck very nicely.
I could not believe the factory would make the exhaust so restricted at this point...I found this online and although it is not an easy install - as pipes need to be modified and new sections installed to make it right/ cost $130 at muffler shop - It is a great value and works as advertised...I also had mileage improve by almost 1 mile per gallon....according to my digital mileage dash program.
It does not have strings but it is a really really nice Gibson.
I had tried another brand, double walled, that tapered in from the collar and would not fit my 3" Ford F-150 tailpipe. The Gibson slipped right on, looks like it was made to fit, and my wife says it looks great. I would highly recommend this exhaust tip to anyone needing one for their F-150.
