THE best mufflers I've ever owned
The sound these mufflers make are awesome, my car is cammed and these mufflers give my exhaust a deep real muscle car sound matched by no other

Work great as Resonators!
My 6.4L Dodge Challenger R/T Scatpack392 started droning a bit around 1800 rpm in top gear (FlowmasterSuper 10, long tube headers, de-activated Active Exhaust, 3" dual pipes). I iinstalled a pair of these in the very back where factory resonators used to be, and the noise level went down by about 50%, and the car now sounds much nicer with the total of 4 mufflers: two Flowmaster Super10s, and two Spintech 9000.

WOW WHAT A GREAT MUFFLER!!!!!
I could not believe how good these mufflers made my 355 chevy sound. Deep but yet a humble rumble and exagerates the cam lope like no other! Thanks spintech I'm really turning alot of heads!!

Killer sound
Installed 2 9000 series Saturday on my 2011 f150 coyote. True dual with x pipe. Sound is awesome! Next to no drone in cab and while cruising you almost can't hear exhaust but when you roll in to the skinny pedal it comes alive. Can feel the truck pull harder in mid-range rpms and higher. Highly recommend. ....... Mufflers RAWK!!

Spintech 9000

Best sound for my 2014 5.3
I switched to spin tech from a flowmaster 40 series. I prefer the extra aggressive roar when I give it a little gas, because the flowmaster was just too quiet for me.

2018 GMC Denali 6.2L
Great sound, and throttle feels a touch more responsive. Can't even hear it at highway speed.
