Deep tone. No drone. Great sound. What else could you ask for

Compact fits where others wont sounds great, different from cookie cutter mufflers.

What can i say i been wanting a set for years and finaly got some. And omg am i glad i did. These are superior mufflers. Ive had every other kind none have produced the sound with no drone. Or built to the standard and craftsmanship as the spintechs. The company head line speaks for its self. Power gains was achieved oh so surprised but happy happy happy. TRUST ME BUY A SET YOU WONT BE DISAPPOINTED!!!!!!

I recently had stage 2 cams, longtubes and a dyno tune performed on my 2014 5.0 F-150. The power was impressive, but the single chamber famous brand muffler I had on my cat back, was so obnoxiously loud and dirty sounding that it made it embarrassing to drive. After searching for options I chose the 3000 series street muffler from Spintech. When I received the muffler I was immediately impressed with the weight of the item, considering it was aluminized steel. I opened the box and found it to be welded perfectly, and honestly was a nice piece that I would rather keep on a shelf and look at, rather than put underneath of a truck to eventually rust. A quick coat of 1200 degree flat black paint took care of that. At wide open throttle, the muffler is refined and almost has the characteristic of an x pipe sound. It's loud as a bear but has a very clean tone. Cruising, it has a very deep tone that lets you know that you've got some power under the hood, and idle is very reasonable yet noticeable with bass tones. What surprised me the most, is that I actually felt a measurable power increase with simply installing the muffler. This may simply be because my engine required more back pressure than I was previously providing, however it was so impressive that I immediately smiled. I understand the technology involved with the muffler and know that thermodynamics definitely plays a factor in the way these mufflers perform. They are like no other muffler on the market and for good reason, they actually work. All in all, I would buy this muffler again 10 times over if needed, and Spintech will be the only brand that I go with from now on. My Boss 302 which I thought was previously finished, will now be receiving some Spintech mufflers.

BUY IT.

I purchased the 3000series prior to having the 9000s on my 4.8 Silverado longtube headers, off-road catless y pipe, and a small cam. Sounded great with the 9000’s just for a daily driver decided to go with something more calm so I ordered this 3000’s and in idle and cruising I did notice a difference it was a little quieter but at the same time sounded a little more throaty or deep, still sounds great WOT. Spin tech will always be my go to brand for mufflers!

Just as other spintechs i have purchased in the past, great sound and well built. Muffler went on a 07 silverado 5.3 in place of stock muffler on stock exhaust pipe. Not loud nor quite, just right for a daily driver and doesnt have the horrible drone as two chamber flowmasters have.

This is my second set of mufflers I've purchased from spintech. The first set I got were the 6000s, which are on my 1976 motor home with a 440 Chrysler.. Love the sound. The 3000s are on a 2004 Chevy silverado and also sound great... Will always buy mufflers from them, great product, and amazing sound!

Just added a set of these as a replacement for the stock system on my 2016 F-150 5.0L. And as usual Spintech doesn't disappoint all the great sound you want with none of the drone you can live without.
Moderate idle volume, more intense obviously on a cold start.
Good aggressive sound on acceleration and a comfortable volume at cruising speeds. Definitely a great option for daily use.

They worked out great on the 72 challenger 340 i installed them on. Sounds awesome really, and the cam really comes alive i have an idle video clip but i cant upload it.

"I had one of these installed on my (long since sold) 1983 Rabbit GTI. The engine couldn't have made 130 net horsepower even after some airflow upgrades so big power gains weren't why I selected a Spin Tech. I selected a "3222" to maintain the appearance of a stock exhaust system while not choking said airflow upgrades, and giving the car a pleasant exhaust burble. That is exactly what it did. The build quality was excellent, the outcome was as desired, and I couldn't have been happier with the product."
