Gets everyone's attention
I replaced the whole exhaust system on my Jeep 4.0 with stainless headers and tubing, running straight into this mini muffler of terror. Fired it up, gave it a rev, and immediately noticed that this thing is no average muffler. Passing down an on-ramp, I feel like a stock car driver coming out from the pits. This muffler is good for introverts, because it eliminates all possiblity for any conversation with a passenger. The sound from this beast is like no other. Even though I have an inline 6, it makes it seem like a high RPM 350 V8.

Awesome product and sound

2017 Ram
Outstanding quality.sounds evil when you hit the skinny pedal but fairly quite at idle. Very little interior drone . They put the Carven R to shame

Sounds amazing!
Got my spin techs Friday and couldn't wait to get them on my truck! Installed an H pipe with the super pro street 9000 and they do not disappoint! A little bit quieter than open headers with a nice deep tone.....

The Best
I ordered these super pro street 9000s on a Sunday and I received them two days later. Excellent shipping time! I have sbc 355 with 1 5/8” long tubes with dual 3” dumped right under the bed and it sounds amazing. So much better than flowmaster or any chambered muffler. I’ll never buy a different muffler again for a v8.

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!

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