1977 Z28 Camaro
When I did the retro on my wife's Z28 it was a gift to her for our 40th wedding anniversary. She had a brand new z28 when we first meet, her first new car. After we were married she had to sell it baby on the way. So I found one restored it and put the 3" SpinTech system on it. I ordered the 4000 mufflers a little too loud for street cruising so that's why I ordered the 9000's. Great product's can't wait to get them installed and hear the difference. Will let you know and send photo's. Thanks for a great product and great customer service.

Spintech 9000
I am a return customer. This is the third vehicle I have put Spintech 9000’s on. I love the mellow tone until you open it up and all Hades breaks loose. Always have got product quickly! I always get asked what exhaust I am running! It is installed on a 2020 Challenger Scat Pack 392 6 speed manual.

Quality muffler ( a little pricey though) had to use due to space limitations dumps at rear axle for now planning on adding tailpipes later kind of loud at a idle sound great when you stomp on it fairly quiet while cruising Thumbs Up!

Muffler
I have a 2022 ford f250 with the 7.3 gas engine and I put the 9000 series street muffler on it and It sounds like a old school big block. It takes me back to my childhood when all there was big carbs and big displacement!!! I'll never buy anything else but spintech!!!

I love them
I installed the 9000’s on my 1967 Camaro with a 406 small block. My dad also has the 7000’s on his 1969 Chevelle with a 396 big block. We love Spin tech! So much louder than my old flow masters and have a lot less drone in the car! I could not be more impressed and wished I had installed them sooner! Great work guys! Car sounds killer!

9000 super pro street
I recently installed these mufflers on my 64 Chevy C 10 with a 283 V8 with Hooker headers. The sound is exactly what I was looking way better than the tinny sound of Flowmaster I actually gave it a nice growl as well as horsepower gain. I highly recommend Spintech mufflers.

9000 Super Pro Street Mufflers
I ran these on a 2003 Mustang Cobra and loved them, but I was a little nervous about putting them on my 2008 CLS 550. I rolled the dice and I’m so pleased with the sound; deep and aggressive, but not obnoxious! I kept my OEM cats intact. 2 thumbs up!

Spintech 9000 Super Pro Street
Sounds amazing on my 5.7 Hemi. No drone inside cab and sounds like a beast outside. Nothing wild and annoying; just how a truck should sound.

Sound
This is the best sounding muffler I've had on my Ram. Has a nice deep, throaty sound when you take off but doesn't resonate in the cab going down the highway at higher speeds.
