  • already installed a bullet, exhaust still too loud/annoying....

    i have a 3" catback w/ spintech muffler

    i liked it at first, but it's too loud now, and pops too much

    i have a dynomax bullet, it helped a little

    i have a hi-flow cat, maybe changing a new stock cat back on instead of the hi-flow cat would make it quieter and decrease the popping by adding a little back pressure? what do you guys think?

    resonated tips will help a lot. quad will help more than dual.

      What made you decide to get the dynomax bullet?

          i decided to get the bullet to quiet it down, it worked a little, its more smooth but it's LOUD. i think it's gotten louder

          i have quad tips welded on.. could i add in resonators or do i have to buy them already installd and cut off / re-weld the tips

          also would a stock cat instead of hi-flow make it quieter?

          its loud and pops like a *****, not too ricey though, a little raspy, mostly LOUD though

          any help appreciated
