got this from car owners group site but backpressure is controlled just like bike correct???? ne wayz here it is its a tin can and don't use a kazoo on the end cut a hole as big as baffle



. If you want noise, and absolutely nothing else, then this is what to get...
Step 1: Consume contents - energy drink will increase driver performance.
Step 2: Remove green wrapping - you don't want people knowing you paid that much for it. Additionally, wrapping may be flammable... you can polish it at this point if you wish.
Step 3: Cut out a hole big enough to fit over current muffler tip. Weld here.
Step 4: Attach a kazoo inside other end of 'new muffler'... airflow will pass through this unit and provide additional meaty soundzzzzzzz...


sounds good i think 2nd opinion would be awesom. my bike is louder than my dads 07 sporty now but doesn't affect air fuel mixture (same flow) but what about backpressure to much?????

i am obsessed w/ it. i don't have the spacer mod cause it was floodin my bike. the muffler is fully in tact just got suthin sliped on from the baffle back. that doesn't affect bak pressure. but can i do the drilling baffle with no spacer mod??
