3" H-pipe

[AZ18yote]

I haven't, I've seen more.good.than bad about their headers and I just figure how can you screw up an h pipe ???

I would say the opposite with so many fitment and quality issues.

So what the point of a 3” H pipe unless you run 3” from the collectors back?

As gasses cool and slow they wont need so much room and can actually become a restriction in itself. Granted you wont see as much benefit with stock headers but it will certainly be better than the puny 2.25" section for the resonator.

It is part of thier cat back kits. 304 and 409 available. Have to call them as the part for just the H is not really advertised. I bought one after mine got damaged.

2.75” on the GT350’s and 500’s.
3.0” ? Who knows if 3.0” to the tailpipe is really needs. Fords GT500 team didn’t think so.
Steeda and a few others are making a 2.75” H crossover mid.

So gt500 doesn't need it, so nobody needs it?

Who really knows.
Not many 2.75” aftermarket S550 systems out there to verify vs. 3.0”
Define Nobody.

You're post insinuated that since the gt500 was 2.75in, that's all was needed. At least that's the way it read.

I can see that.
Yeah, I’d think power levels past a tuned GT500 is getting into the 1 or 2%’er’s. Big power = Big tubes.
It would be interesting to see the results of a 2.75” vs. 3.0” system with the same muffler internal design.

Mike didn’t test 2.75”
Mike deserves an award for the intel he shared for free !
