Steeda H-Pipe with Roush Axel Backs help

[Dane60]

I’ve had my axel backs since I’ve gotten my 17 mustang gt. I went and put a Steeda h pipe on and yeah sounds nice whatever haha. But, when I excel past 2500 rpms I get a loud trumpety noise as if it’s a clapped out pick up. I was wondering if it’s a leak from my clamps or what. If none of that made sense I’m sorry haha.

I had the same setup, I no longer do for that reason. Maybe try to weld in resonators.

I had Steeda Axel (same muffler) backs on my 2020 GT. With the Borla Switchfire it was so trumpety. With stock resonator it was fine, sounded great. Added the Borla and it was a mess. I now have Ford Racing Sport by Borla with 2 small race mufflers welded in after the xpipe. Sounds much better and still very aggressive.

I have never heard an exhaust sound anything close to a trumpet being played. What is this "trumpety" sound you speak of?

How’d you like the steeda axle back?

Not sure if sarcastic or not lol. But perfect example was back when I had Corsa Xtreme setup and was all else stock it sounded great. Added long tubes and boom annoying trumpety tone. Added a pair of Vibrants and it killed that tone. Ultimately cut off the Corsa mufflers and added AWE Touring rear section to the double x mated to the long tubes. Favorite sounding exhaust so far on this build.

I wasn't trying to be sarcastic. Your example doesn't explain what "trumpety" sounds like. I've heard setups that sound very raspy, and I know people have used resonators to kill the rasp. Maybe that's what you mean?

I think the trumpety sound you are referring to is the rasp from opening up the exhaust. I just put catless headers on and the rasp is embarrassingly loud when you pass the 2k-2500k rpm mark. I want to add the Magnaflow Tru-x to quiet it down but I sort of deal with it because when its wide open throttle is sounds really nice. I hear too many stories about how quiet the exhaust gets with the magnaflow tru-x.

Ah got it. Dug up some old vids though they don't really do the trumpety tone justice lol.

Xtremes after long tubes added (trumpety)

Im sure it’s worse in person but you can tell through the vid it is trumpety. How long that setup last? Lol

I kept it like that for a couple months at most. A pair of Vibrant 1794s killed it before I swapped out the rear section all together.

Did the Vibrants make that much difference?

Ya killed the trumpet tone and brought the volume down a bit too. I'll find a vid of that for comparison.

With an x pipe I didn't like it, sold it and got the Ford Racing by Borla Sport. Happy with that.

Its not just the rasp although that was definitely part of it, its had an unGodly howl/trumpety sound and not in a good way. Not to mention it was so loud I definitely would have got a noise ticket.
