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

Posted by B.U. on Oct 13th 2018

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.

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.

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

Posted by Jacob on Jul 17th 2018

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!!!!

blew my mind

Posted by Darren on Jun 23rd 2018

Absolutely fantastic sound! I have been a fan of another famous exhaust company for many years and then a friend told me about spin tech. I had my doubts but decided to give it a shot when I seen the prices were comparable to my previous favorite company. It blew my mind when I first fired up the hemi! If you have any doubts, take my word the spin tech 9000 is amazing. It is not for the faint of heart because it is fairly loud so if you don’t want to hear the power you’re beast has then don’t get it but if you love the rumble then you will love this one!!!
