I bought them because a friend mentioned them. He said they sound really good. Well I can't lie they sound real t a dozen muffler. Definitely worth it.
Got the 3" for my 05 GTO. Sounds like a T rex now! I receive compliments all the time.
Best sounding muffler on the 6.1 srt8 jeep
They sound really good. Way more aggressive than I thought with longtube headers. They will probably get me kicked out of the subdivision.
I just had them installed today they sound awesome
These mufflers are great and made of good quality love the sound on my foxbody if you want an aggressive sound and don’t mind to be a little loud then these are for you. Well worth it in my opinion
Great sound. Exactly what I was looking for.
Great compact design, very well built muffler. These mufflers have a deep aggressive tone with virtually no drone on my big block chevelle. i will be using these mufflers on my other builds going forward.
installed 2 of the 9000 series and i have to say they are the best unique sounding mufflers ever. Love them way better then anything else ive heard.
Was skeptical to be honest. But man I was impressed. Quality muffler.
Better-than-expected will definitely order more in the future for other vehicles. Thank you for high quality product
These things are awesome! I removed some Sportsman 3000s that were nearly 20 years old and I was worried that if I put the 9000s on they would be too loud. The exhaust system on my mild built 454 has 2" primary headers feeding dual 3" pipes with a x-pipe, super pro street 9000 mufflers, and tailpipes to the bumper. It has a very crisp fresh sound now! Thanks Spin Tech!!!
