H-Pipe Opinion

[turbo]

Please respond IF YOU CHANGED YOUR CATS WITH AN OFF ROAD H PIPE. I'm looking to know who makes the best fit direct replacement O/R H-pipe. Not interested in x pipe. Thanks. Stock exhaust manifolds. no headers

The lethal H pipe fits perfect and is made of 304 stainless. Stays looking great.

Car sounds great with stock manifolds and an H pipe.

I since changed and went with headers and an H pipe. My car is actually too loud now but I picked up 30 hp from the long tubes.

you have any idea the horsepower gain with just an H?

I run MRT Max Flow uncatted H Pipes. They work and sound great. The only issue I had was around fitment. The exhaust tips stick out about 1 inch over stock. Other than that, It's been working just fine for me.
