Need opinions
I recently installed bbk long tubes with off road h pipe to existing slp catback and the car now is TOO loud and sounds like a trumpet above 2500 rpm. I absoulutly hate it but liked the sound when it had the stock h pipe in it so leaning towards installing high flow cats but also considering changing the mufflers. And go.......

Magnaflow
Slp powerflo Steeda Borla xr-1 I run the magnaflows with lts and or x. No trumpets over here. Can be calm or insane. Been through a lot of exhaust combinations but I've had this one for years and have no intention of changing it. Any of the above mufflers will take that edge off, sound great and flow great.

A trumpet?! I don't think I've ever heard that kinda sound from a V8 lol. Does it sound like glasspacks with the SLP's?
If you still want a louder sound, I think I'd try an off road X midpipe.

Re: Need opinions
Sound clip? Yes a trumpet as best as I can describe.

Adding cats makes a big difference. I had hollowed out cats for a while. Putting high flows back in made a big difference.

Re: Need opinions
I don't think a sound clip of mine would help. Mine has an H pipe too. I have Borla stingers on mine. The x pipe usually ads a rasp to the sound. I would think that would fix a trumpet type sound.

Re: Need opinions
X pipes don't add rasp. Running an or pipe, be it x or h, with imitation mufflers aka glasspacks like stingers, lm2, lm1, magnapacks are what causes the noise he's getting. Cats will help, but not as much as a muffler with packing will. Cats will take the majority of the rasp/blat sound away from inside the car, but outside it's still a blatty noise from 2500rpm and up if you're giving it more than 1/4 throttle. I learned that watching my car get dyno'd years ago. I thought I had cured the rasp with cats because it sounded better from my point of view behind the wheel, but being outside of it that wasn't the case.

Re: Need opinions
I agree with 311-420, you'll want a good muffler with packing, or at the very least a catted mid pipe. You'll still have some rasp, but the cats will tone that down a TON!
What did you end up doing?

Sometimes what we hear inside the car is not the same as people outside the car hear. Best way to know would be having someone drive your car while you stand outside or make a vid yourself and watch it if you can't have someone drive it for you.
