Description

Super 10 Series mufflers are constructed of 16-gauge 409S Stainless Steel and fully MIG-welded for maximum durability.

    • Sounds loud
Review Image by Prophetdjs Prophetdjs
The media could not be loaded. These are terrific I installed them on an Acura TLX Type S & the sound is virtually straight piped so I had to add a resonator now it's perfect, but without that resonators it sounded like a Ferrari just too much attention for me. Go get it you won't regret your decision ... show more

    • but it certainly feels like it pulls you into your seat stronger
Installed on 2008 Ford Fusion V6 with k&n cold air intake, resonator and cat removed (header cats still in place) Put in place of the rear Y pipe, put in 2.5 inch pipes from the flowmaster to 3.5 inch tips out the back. Tone is surprising, certainly loud, deeper with more of the underwater rumble than you'd think the 3.0 can put out. Comparable sound to a v8 with a flowmaster 40 or so, not as loud as most muscle cars, but some. Performance is improved mostly with initial launch. I can't say if it added any actual power or improved any times because I have not tested either, but it certainly feels like it pulls you into your seat stronger. I'd recommend this to most people looking for a good sound that's got a respectable name without getting a raspy ricer fart can or buzz. I feel like youre buying a name with something like borla, when you can get the job done here without going as low as the 19.99 thrush clearance special. ... show more

    • threw this onto my 3.5 Chrysler 300, it sounds GREAT.
Threw this onto an older 3.5 sxt mopar, it sounds great at idle, it almost has a choppy, cammed sound and really drowns out the "hair-dryer" sound coming from the engine bay that's VERY noticeable in stock form. I got rid of the resonator as well and this car is STILL quiet at idle and warm startups. But it does have a nice deep rumble to it, I get to avoid cops and have fun on my own. I'm not complaining. ... show more

The media could not be loaded. Sounds amazing on my "81 Chevy El camino 305c v8! Went with the dual side pipes with my new catback exhaust system. Looks sick! and sounds better than I imagined. Great purchase!

    • Not as load as you would think
First time buying flowmaster good product just a bit disappointed. I was told by many people it would be to load and it's very Melo. I had a cherry bomb on my 2004 dodge ram 3.7 and it was louder. But I do like the sound of this as well good growling. Good price good product

    • Blown away!!
The media could not be loaded. Sounds absolutely amazing. This is my 2008 Dodge Charger 2.7l V6. Sounds like a V8 with the flow master. I did a muffler and resonator delete. Then I put the flow master in the middle and did duel straight pipes out the end of the car. Couldn’t be happier with the results. I think the video speaks for itself. ... show more

    • Great sound for 6 cylinder
Sounded great on my 2010 Nissan altima v6. It's super difficult to find a muffler that will make a 6 cylinder sound good but thankfully this one was perfect for my application

    • Use a smaller diameter muffler than you're planning
Everyone typically goes for a 2.5" in and out when in reality, with this style muffler in particular, there is almost no restriction to help with back pressure. There are literally 2 small baffle plates welded in this muffler. What I found that ends up happening, is you get an undesired sound/tone from the exhaust. It sounds as if you've just cut your exhaust off at the CAT. Especially with a single in, dual out muffler like this, go a bit smaller on your out diameter and all the way out, you'll get a better sound. ... show more
