    SpinTech Super Pro Street 9000 Muffler

    The Super Pro Street 9000 is the most AGGRESSIVE muffler we make for sound and competition!

    Patented design converts sound energy into thunder. 100% Welded construction. Spin traps generate vortex flow effect. No packing to burn out. Scientifically calibrated Venturi scavenge gases for dramatic flow increase.

    Super Pro Street 9000 have:

    • Smaller case size: 9" x 4" x 6"

    • Will fit most vehicles on the street today

    • Great sound with maximum horsepower gain

    Customers love the small case size and multiple configuration choices. For truck applications choose a single in and dual outlet, usually 2 1/2" or 3" inlet with a dual 2 1/4" or 2 1/2" outlet. Our 9326 or 9436 mufflers. Recommended for use on newer vehicles with multiple CATs or none at all.

    Super Pro Street 9000s have found their way into racing events with winning results!

    Warning: Very aggressive muffler!

    Rev up the RPMs. Hear your engine roar.

      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

      Posted by Hayden Collins on Mar 10th 2022

      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

      Posted by William Heiser on Feb 3rd 2022

      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

      Posted by Moabounce2 on Feb 3rd 2022

      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!

      Posted by Fernando Muneton on Dec 22nd 2021

      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

      Posted by Mark Polt on Nov 2nd 2021

      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.

      These sound MEAN

      Posted by Bradley White on Aug 26th 2021

      These sound amazing. They are loud but also have a great, aggressive tone. The drone is very minimal as well.

      Phenomenal

      Posted by Will Harwell on Aug 21st 2021

      2015 Mustang GT performance pack. This company has always come through for me on five different vehicles. Incredibly fast shipping, perfect fitment, and amazing sound. Big box companies pale in comparison to spintech. I bought my car with 3 inch magnaflow, I will be throwing it away to replace it with spintech 9000s
