392 Challenger SPS
The sound is awesome. I installed these on a 2016 Challenger 392 SP shaker. The tone went from high pitched scream at high RPMs to a growl...just what I was looking for!

5.9 jeep grand cherokee
I put this muffler on my 5.9 Jeep Grand Cherokee it sounds great it’s their loudest muffler but it’s still not to radical to drive every day! When your light on the pedal it’s not to loud but when you lay into it it just screams! And best of all zero drone absolutely zero ! Don’t think twice just order yourself a set!

Aggressive sound
Installed on my 2017 Silverado 1500 5.3L. Deleted the resonator. Has a nice tone and is just aggressive for my liking. little or no drone. Excellent product. Here is a video of the exhaust https://youtu.be/6IHLg7V6qaw

Superb aggressive sound and loud!
I absolutely love this muffler. I didn't expect it to be so loud! The sound quality and reverb Spintech air flow provide high quality sounds and cause heads to turn! I've had a lot of comments on the sound. I've combined long tube headers, K&N CAI, a 3" Y-pipe, and this Super Pro Street 9000 muffler together for the ultimate exhaust combo. Love the increased MPG, but hard not to floor the pedal anymore! I wish I would've waited for the custom order to get the exact measurements I needed, but the stock muffler measurements worked fine with some minor piping modifications and welding. Thank you again Spintech and keep up the great work!

Scares Children
Likely the best sound you can get out of a modular V8 mustang. It sounds deep at low rpm's but gets angrier and louder throughout the rpm band until it goes on full raging race-car sound and frightens the elderly.

best ever! customer for life!
These are by far the best sounding mufflers out there. Amazing deep rumble with a nice throaty tone. Little to no drone at highway speeds where other brands have a ton. Well built must buy!

Buy this Muffler!
2018 Dodge Ram 1500 big horn....just installed...WOW! Even the installer was impressed..:a little drone, but the sounds make up for it!

Excellent Muffler!
I purchased this muffler to replace the flowmaster 40 series that i had on my 97' Chevy C1500 due to me being annoyed of the drone, and man was i not disappointed, it has a deeper and more aggressive tone than the Flowmaster.. especially at wide open throttle! Was worried that it was going to be obnoxiously loud but it is not, it drones a bit between 40-50 mph but not even noticeable

best muffler hands down
I purchased this muffler for my son and I mustang that we built this summer. Very well built, you could pull a tank with a spintech muffler and not hurt it. And the sound is amazing. We get so many compliments on the aggressive tone these mufflers emit so much so that I purchased another one for my daily driver. And just like the first two mufflers, the third one is just as good. Keep up the good work spintech. You can’t gonwrong running a spintech.

I have not gotten the chance to install these mufflers yet but they appear to be built very well. I cannot wait to see how they sound on my G8 GT.
