Will replacing the x pipe and putting axle back muffler deletes on it add gains like a full exhaust will? or will it add anything at all?

Also, what's the best mid pipe to get paired with axle backs that'd make the loudest, deepest sound?

X or H pipe?

THanks guys, this forum is awesome.

It would help if we had more info. What the hell do you drive? What mods do you have done to it? etc.

FWIW, on my old '85GT (heavily modded ~400HP), I ran some Mac hedders with 1 7/8" primaries to 2 1/2" exhaust to the old school 2 chamber flowmasters (I guess they're called 40 series now), and 2 1/2" tailpipes. The sound was really loud and really deep. To put in perspective, the car was so loud, I would have to yell at my passenger in order for them to hear me.

PS: I ran straight pipes, not an H or X. A lot of people said that my car sounded different than all of the other Mustangs that they had heard.

And just curious, does it matter what the car is, wouldnt replacing the mid pipe and doing muffler deletes have the same effect on every car... or no?

Thanks.

i wouldnt recommend doing muffler deletes, look up some vids and see if you like the sound, also i personally like x pipe it provides for better flow imo
and back to your question a full exhaust system would probably provide much better gains/flow than what you plan on doing

X pipe will always show better hp over an h pipe because it can exhaust scavenge and the exhaust pulses work together.. Good stuff. X pipes generally sound good (on mustangs atleast) and give lots of mid and high range tone!

This is an old thread, but for anyone else reading, an offroad x-pipe like UPR's pipe will typically add around 20hp. There's not a lot of power to be gained with the muffler swap on a stock-ish S197 Mustang though. (but they change the sound)
