  • What are the performance gains on the Flowmaster 80s?

    How much does it add to the Horsepower on the dyno tests? How much are they + install for a good price?

    I'm also planning on putting in B&B Tri-Flow when I have the money, this is just to get the gay stock muffler off my car for now. [img]smile.gif[/img] Think this is a good idea or should I just wait another 6 months with the stock muffler?
    \'01 Trans Am WS6 5.7L M6<br />Stock now w/ K&N and whisper lid<br />Coming soon: B&B Triflow catback, MAF, 85mm throttlebody, headers, supercharger?

    hey,
    i have Flowmaster 80 Series Muffler w/dual 2.5” Chrome Slashed Cut Pipes. i paid $80 for the muffler and like $130 for the pipes and install. they look and sound great. sounds just liek v8 on start up, but after 3-3500 RPMS it's a different story. i like em tho, worth it i'd say. i had em installed at Tuffy and bought the muffler at Pepboys. i noticed a bit of a diffence after i installed em, need intake to get full effect tho, i only have k&n filter. so, IMO go with the flowmaster 80 and all that.

    thx
