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