Header pipe question

[Toomey]

My 08 HM has a Leo Vince mid pipe (cat eliminate pipe) and Termi cans with the OEM header pipe.
My question is would there be any performance advantage to haveing the Termi head pipe?

From what I've found dyno testing, a stock bike with the OEM headers (with a cat remover) works really well for power, I have tried an aftermarket header pipes with a larger diameter tubes, but other than looking "COOL" for me they lost HP & TQ, the aftermarket headers will probley work better on a modified engine with cams, porting, modified airbox or a system like the TPO's, or just anything to make the engine "breath better" (more in, more out) but for a stone stock engine you will be surprised how well the stock diameter tubes work, hope this helps, Aloha Alex

I wet to a track day only to hear, and see a 998RS.. Man those Pipes just excite the erogenous zones! Anything within a 200metre radius just looked like a toy.

Im was also wondering about this, as I have the same setup with Termi cans and cat remover, but OEM headers. I was a bit dissapointed with the sound, my old 900 monster with termis had alot more and deeper sound. So Im thinkning its the constricted midpipe with its small diameter thats doing this, also considering the much better sound in the 2-1-1 termi with the large headers.

I have Zards at 45 mm from stock at 39 mm and the difference is well noticeable all over the power band when fueled up correctly and the sound is much much deeper boom.

My system is K&N, moded top and bottom airbox, DP ECU, Zards Termi slipons opened.
