100% Bad Ass!
The Spintech 9000 Super Pro Street has transformed my 2010 Dodge Ram into a mean sounding street beast. The difference between stock and this muffler is a deep rumble, with very little to no drone inside the cab at highway speeds. Well done, Spintech.

Amazing sound
I put these on a mild sbf 302 with a ford E303 cam.im running long tube headers with a 3” off-road H pipe,spintech 9000 with 3” tail pipes.I couldn’t ask for it to sound any better,not as loud as you would think but still really noticeable.

Amazing sound !
Deeepppp start sound and when you get on it it sounds absolutely amazing. Little drone in the higher rpm range but at cruzing speeds it good to go.

If you’re having second thoughts about this muffler. This review should clear that up. My car sounds amazing now, better than anticipated. You won’t be doing wrong going with SpinTech!!!

9000s are the best sounding
I’ve had the 6000s in the past on my 5.7 Hemi. I had longtubes no cats and 3” true duals. Had a nice tone but didn’t sound good when the rpms increased due to no crossover. I added an h pipe with the 9000s boy what a difference. Sounds deeper louder raspier just overall NASTY. I haven’t heard my Hemi sound so good! I think I finally found an exhaust I can live with for the life of my vehicle. I’m sure the 6000s would have sounded good with an h pipe but I like loud and 9000s are so much better.

9000 Super Pro street
Just put these on my foxbody with a 408W. Sound awesome at idle. Very loud up top. Semi obnoxious, yet exactly what I wanted.

9000 sound
2019 Ram 1500 - Not much louder than stock muffler. Even tried with resonator removed.

9000
Best sounding muffler for my 557ci Ford. Made the mistake of trying Flowmaster and it sounded horrible.

Spintech 9000 on a 1997 chevy 2500 5.7 vortec
This muffler was well worth the money, it has a violent sound to it when the motor is on load at higher rpms, and sounds like a solid clean loud V8 when at idle. If you want to check out a video of it on my old school small block Chevy truck, go to my YouTube account, mutanay77

Best Muffler Ive ever used
I have used Spintech Super Pro Street 9000s on multiple cars. Most recently I put them on my 2018 Charger 392 Scat Pack and they sound amazing! As always. Great quality product. Fantastic sound. Deep rumble at idle and raspy scream at WOT. Love Spintech!!!!
