[mxpimp2000]

i sold my full system TC shorty exhaust due to sound levels and racing requirements DBL levels, i was wondering how much will i be losing in HP i have HMF slipon with stock headpipe now

not sure. my bike also has the tc shorty but i havent had anything else on it

[mxpimp2000]

i believe im gonna miss it, and those pipes are hard to come by

[#17YFZRACER]

everywhere i race its still legal:D i coated mine with vht in a flat black. did u run ur pipe with the open end or the discs? i cant get it tuned just right
