They range between 20-80 bucks, that was just the best size on ebay. it was 32 plus 10 for shipping. I should have it in a few days ill post pics when its installed. Im curious to hear how its gonna sound, might not notice much, or it could make a nice deep tone, from previous exhaust i had i know it won't sound ricey or raspy so im excited

 

Cool! Definitely post sound clips!

 

not to bump and old thread. but i just did this today as well. difference is slight, but definately sounds nicer than stock.

yet to really open it up WOT. also blocked off my airbox resonator as well for good measure (airbox is already gutted, and running mugen filter).

great result for the money, it cost me $40 AUD which si about 30US.
