Thanks for that, so more than likely slip ons are fine? V & H eliminator 300 is what my shops recommending and i like the look and sound. I was just concerned the step down on the factory header was going to be too restrictive.

I cant say for sure, im no expert, but It seems longer pipes are better for the M8, and if you dont want to use a 2 into 1, some slip ons with some reversion control may be the best option.

Short shots were what I wanted to get at one point. But you can't argue with dyno results; the M8 literally loses power with short 2into2 systems. Inserts such as Thunder Torque or lollipops can help return some of the lost torque, but they may only bring it back to factory-mufflers level power. For that real Stage 1 effect, any full length 2into1 will give best results. S&S SuperStreet, Thunderheader X-Series, Rinehart are all good choices.

But yeah any shorty pipe that doesn't have a crossover scavenge should be avoided for the M8s.

Thanks guys, i went with the eliminator 300s and ordering the S&S 475c cam kit, my buddy used the same setup and it ran 110 wheel hp on the dyno so i figure that's good all round power as the torque curve and power range is more suited to my riding.
