So I had the kr mufflers prior to installing the off-road X and it sounded great. The car sounds great at idle and low rpms but at around 2 and 3k the sound goes full on crazy LT1 sound. The setup surprisingly has little drone at 60. I’ve read some have installed magnaflow weld in mufflers before the over axle to smooth the sound out ,which I’m considering, just don’t want to spend a ton on trial and error. Is this or another axle back the answer or do I have to reinstall the stock mid pipe? I don’t mind loud, I just want a smooth sound. Any suggestions are appreciated. Thanks.

put 2 hi flow cats in, or go to exhaust shop and have a resonator put in on each flow tube.... otherwise you need to change the axlebacks ( however most axlebacks have the bro gurgle truck noise) unless you buy a 10+ GT500 axleback paired to the o/r x and that is the best all around sound/no drone or bro noises

Thanks for the replies guys, just ended up going back to the stock mid pipes. Cut my losses.

There are countless threads out there raving about how great the KR mufflers sound. I believe your issue is the X pipe. You can pick up an off road H pipe for a few hundred bucks and give it a try. If it provides the sound you want sell the X. If not, sell both the X and H. There are always people looking for off road pipes.
