Pro Street 6000 Muffler


Product Description

SpinTech Pro Street 6000 Muffler is very versatile because of its compact size. The Pro Street 6000 will work on many vehicle applications; from the mini to full size truck; imports to muscle cars. The Pro Street 6000 is a very aggressive muffler.

The sound level 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.The Pro Street series muffler is a direct descendant of our very popular Pro Shoot-Out series with slight modifications for more efficient sound reduction. Recommended for use on newer vehicles with multiple cats. A perfect muffler for newer Mustangs, Vipers,and newer trucks, when duals are installed. The Pro Street will give you an aggressive yet moderate tone. Interior sound is typically at comfortable levels. Even though this muffler was not intended for racing purposes, it has found it's way on many race cars with very competitive results.

In comparison, Pro Street 6000's are a little bit quieter than the Super Pro Street 9000's.   

Case Size: 4" x 6" x 12"

  1. Good sound but... 4 Star Review

    Posted by on Feb 23rd 2018

    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?

  2. Beat sounding mufflers on you can buy. 5 Star Review

    Posted by on Dec 18th 2017

    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.

  3. Great 5 Star Review

    Not too loud and sound deep throughout the ranger 4.0 ranger

  4. sounds deep 5 Star Review

    Posted by on Dec 1st 2017

    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.

  6. haven't installed yet, but 4 Star Review

    Posted by on Oct 27th 2017

    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.

  7. great sound/ too loud 4 Star Review

    Posted by on Sep 24th 2017

    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 .

  8. raspy 5 Star Review

    Posted by on Sep 8th 2017

    I have been a diehard flow master fan for more than 20 years. But seems every mustang in my small hometown sounds the same. Trust me when we say heads don't turn anymore.....Try spin tech for a awesome deep throat growl. Now instead of heads turning people are falling down to see what's new in town.

  9. High Quality Muffler 4 Star Review

    Posted by on Sep 5th 2017

    I just recieved my 2 Spintech mufflers today. Havent had a chance to put them on yet, but they were packaged very well and were made of high quality steel. All the welds were done right and grinded smooth. Overall very happy with these mufflers, and from seeing the videos on the they should sound just as nice.

  10. Sounds great on 2015 Silverado 1500 5 Star Review

    Posted by on Aug 30th 2017

    After countless videos and debate on what muffler I wanted on my truck, I settled on the Spintech 6000 and couldn't be more impressed. For the 4.3L engine, it sounds fantastic and not too loud for daily driving.
