      Great muffler for custom dual outlet exhaust install

      I bought this muffler in order to add a custom dual outlet exhaust to my 2013 Ford Focus Titanium hatchback that only had a single outlet exhaust as original equipment. The Flowmaster Series 80 created a low rumble at idle and a deep loud satisfying growl whenever I step on it. Just as I was wanting and without any droning and significantly quieter when I'm driving just normally for maximum MPG. The muffler arrived on time, well packed and in perfect condition. Highly recommended.

      Very pleased. ....

      I've always been pleased with Flow master products. They are the only company that offers a cross flow style muffler for my 3rd gen camaro. In addition, this muffler is only $60 more than the traditional muffler.

      mid engine sound

      Install was not too bad requiring the hangers from the old muffler welded on and 3 90's. The sound was worth the work! I also did the Borla tip which does enhance this! I'd do it again.

      98 camaro

      I received my Flowmaster 80 series muffler for my 98 Camaro that i bought off Ebay. It's a good looking muffler, it installed perfect behind the back axle the way i wanted it. My only complain is the fact the flow i use to have has decreased. My Camaro originally had a CherryBomb Vortex on it and it flowed amazing. If i could go back, id put the same muffler i had on it back on it. but the old muffler had a hole in it. Id really like to know if i could receive my money back.

      Great sound in every speed range!!

      (AA)got muffler here in record time. All ratings(excellent) cause that is how it is. Installation real snap using friends muffler shop. Price a wee bit less than local. Quality "Flowmaster"(A+). My '04 Grand AM GT sounds "BAD TA THA BONE"! No offensive sound, but will definitely be heard as a low, mellow, rumble, parked, & talks to ya real good off the line. When up to speed ya got a low mellow, just right, sound which makes ya sit up just a little more in your seat and smile! YEAH BABY! CRUZ'IN!!!

      Perfection

      My application for this 80 Series Flowmaster was a 1992 Cadillac Sedan DeVille. The sound quality is terrific, as well as the visual appeal from behind the vehicle. Everyone that hears my car now calls it the DeVille SS/RS. I Love It!!!

      Grand Am GT Flowmaster 80

      The Flowmaster 80 series muffler sounds great on my 2004 Grand Am Gt. It has a nice low rumble to it when the car idles and isn't that loud at cruising speeds. I did notice an increase in throttle response and horsepower. Overall, i would recommend this product to anyone who wants a nice sound and appearance to their car.
