SpinTech Pro Street 6000 will give you an aggressive yet moderate tone and is very versatile because of its compact size. The Pro Street 6000 will work on many vehicle applications; imports to muscle cars, mini to full size trucks. A perfect muffler for newer Mustangs, Vipers and trucks where duals are installed and for use on newer vehicles with multiple cats. The Pro Street 6000 is a very aggressive muffler.
The Pro Street series muffler is a direct descendant of our very popular Pro Shoot-Out Race Muffler Series with slight modifications for more efficient sound reduction. Even though this muffler was not intended for racing purposes, it has found its way on many race cars with very competitive results.
The Pro Street 6000 interior sound is typically at comfortable levels. Sound levels will increase by increasing the tubing size. This modification can also increase interior sound levels as well as creating interior resonance. The larger the tubing, the louder it will be, and could result in loss of power.
In comparison, the Pro Street 6000’s are a little bit quieter than the Super Pro Street 9000’s.
Case Size: 4” x 6” x 12”

I installed these on my 2018 Dodge Challenger R/T 392 6.4L ScatPack. Previously I removed the factory mufflers, and lost some torque at low RPM. I put these Spintech 6444 (offset in/out) where the factory mufflers used to be, and the torque is BACK. Love the sound too. Thanks, Spintech!
I've had spintech products installed on other vehicles and it lives up to expectations every time. If not exceeds expectations. I absolutely love the products.
Very well built and great sound love it on my 6.0 chevy
When I had the 3800 swap done on the Fiero, I bought a complete exhaust from West Coast Fiero that used a SpinTech. That has such a sweet sound to it, when it came time to put a pair of mufflers on my C3 Vette, it was a no brainer. The 6000's are perfect on it. This was my sound check before finishing up the installation.
My exhaust system for the 3800 swap Fiero came with a SpinTech from West Coast Fiero, and I've loved the sound of that system for years. So when it came time to pick out a pair of mufflers for my new toy, it was a no brainer.
This was still missing tips and hangers when I videoed it, but I couldn't help testing it out before finishing up the install.
I love the sound it produces. It blows a FM40 out of the water for smoothness. It’s built like a tank and gives a v6 a great sound without losing tone through all rpms. However, I’m running a SI/DO on a 4.3 vortec and it doesn’t produce much sound at idle...I can bearly hear it at all when driving...but it sounds good when I stand behind it! Maybe I’ll invest in a high flow cat or should’ve went with a 9000?
This is my second set of 6000 series, love the sound. I had 9000s on another venicle just a little to loud. The 6000 have a great sound for a Big Block I run 3” pipe with X pipe, 700hp 540BBC in a 69 Camaro.
Not too loud and sound deep throughout the ranger 4.0 ranger
3Rd spintech muffler on 3 different type trucks.Put 6000 on a stock 2007 jeep grand cherokee 5.7 hemi replacing cat back and love the deep sound when getting down on it.No drone like a "BLOWMASTER
and its actually quite below 1800 rpm but stab the go peddle and it wakes up with a awesome tone.If you have a nice cam or nasty you gotta go with 9000 but this is a single in and out and suv that wont get modded out .And every e-mail gets answered by Ron as to what you want or need,wont ever buy another muffler for any of my vehicles.
I realy like the sound of this muffler and it was a good price. Excellent service and fast shipping. I will be buying from again!
The build quality of spintech street mufflers can't be beat. Heavy duty, not the tin can sheet metal found on other manufacturers products. Haven't finished the engine build so haven't heard the spintech in person yet or i would likely have given a 5 star review.
I put these on my 340 Demon. Sounds great, but too loud. I run a 2.5 in exhaust with an x crossover and have turndowns cut at an angle to blow the exhaust out the rear. It is an 11-1 comp 340 with a Comp Street Roller. Probably would be quieter with a full exhaust. Took them off the car as they were too loud. They also had a bit of a drone. I should have contacted Spintech and asked their opinion on which muffler to buy for my car. I did not, so that is on me. I should have gone with the
Sportsman Street 3000 .
