Better than expected

Fits right and will definitely increase performance. The truck downshifts much less on the motorway and does not lose speed even on inclines.

Pros
  • Great for me
Cons
  • Only available in white

Good quality Gibson product

Exactly what I expected. Good Gibson products. It fits snugly, so I recommend having a couple of ratchet wrenches and patience for installation.

Pros
  • Excellent construction
Cons
  • Not sure

Overall good for exhaust and emissions

This was the best deal on the web. I paid 425.00 free shipping and would do it again. The bolt bag was open, but everything was in place.

Pros
  • Test for one year
Cons
  • Weight

I bought them to try and get away from cracking factory manifolds and rusty aftermarket leaks. I didn't expect any increase in performance. If I had known what a performance difference it would make I would have done it a long time ago, my truck has a 6 speed manual and I use a high gear on most hills and on big hills I usually shift to 2nd down the aisles. to pull, I'm…
