I narrowed down my search for exhaust to the EPCO, but I still have a few questions about set up. On a '06 Speedmaster, what size are the stock main jets and pilot jets? I like the straight cut EPCOs more than the slash-cut type. Does anybody run these? IS there a sound/performance difference between the 2 pipes? BTW, the reasons why I'm going with the EPCO are budget and noise level. I hear they're not awfully loud, but do give you a good rumble.

pretty sure they come with the jets needed, and i imagine there is no difference in sound/performance just based on the look of the end tip

My Epcos came with jets and new mounting bolts, very handy to have if you run into the common problem of having to remove the heads on the original bolts.
The Epco pipes have a nice sound and gave me a nice power increase.

Only the mains needs changing. When I got my Epcos a few years ago, they came with 160s. Even with the Freak, I ended up changing them out to 150s.

160's?? WOW! I'm thinking 130 or 132's. Uni filter with snorkel out. At least that's where I'm going to start.

it all depends on weather you have your airbox or not

Hey Joeknows, go with the Triumph straight throughs, they come with jets. Once fitted they have that vintage pop and crackle Triumph were famous for.
