Quality
Always top notch Quality. Haven't gotten it installed yet so that's why the 4 stars . Bought a 3.5 inlet and outlet. Gonna be 2.5 off the headers down to a single 3.5 out the bed side of my Dakota.

Overall
Shipping and order processing was top notch, I received everything within a week. Only odd thing was one muffler is roughly 1/2" shorter than the other, but for my application it doesn't matter. All together though I'm very happy with them.
-
great product
excellent build quality. can't wait for the customer to finish the build so i can hear how they sound.

Perfect
I bought these already knowing the sound. They are deep and loud just what I was going for. Not my first spin flows but they are my first super pro streets. Love them got them put on today and they are mean!!!

Muffler
VERY aggressive!! I love it! A little more drone in the cab than I'd like but it's not too too bad!!! 10/10 recommend!!

Sounds awesome!
If you’re looking for the bada** sound out of your Foxbody Mustang, this is the muffler for you. There’s nothing like the sound that comes out of the exhaust when you mash the gas pedal to the floor. The 9000 Super Pro Streets are the way to go. It seems as if the motor breathes easier with these mufflers on.

Awesome sound and great quality
All around awesome muffler great sound gave my truck the tone I was looking for 10/10 would recommend

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.

9000 SUPER PRO STREET 3 INCH
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!
