first question, why do you want to shorten it? what that does i'm not too sure.

but the way i would shorten one is i'd probably use like a band saw for cutting and shortening it then TIG weld it all back together.

how dose the baffle come out. id take that out then cut the outside down to what u would like then find out how much of the baffle needs to be cut and putt it back in.
As much as i like the sparks i think they are to long prolly the same reason you want to shorten urs.

ive never run sparks, but they are def. one of the best pipes out there IMO. but they can get pricey. get an HMF s/o for a couple hundred and you will be VERY happy. plus HMF has won "best pipe" in DIRTWHEELS.

I have a sparks and love it. It sounds great and makes tones of power.

I will be shortening mine soon because it keeps getting hit when I race. My tip looks like crap. I would prob use a chop saw or a band saw.

To turn your Sparks into a shorty (although mine is an X6) you will need to drill all of the rivets out (including badge). Disassemble the pipe. Use tape to tape where you want to cut the canister. Tape around the diameter of the pipe and make sure the tape meets up (this will act as a guide when you cut the pipe and assure u a straight cut). Use a bandsaw to cut. After u cut the canister, you will need to cut the same amount off the baffle (but on the opposite end). Then rewrap the baffle w/ silencer packing. Put the pipe back together and drill new mounting holes... Then rivot your new shorty together

As far as power (on a fully built 440)... lil peppier throttle response and nothing else... exhaust note also not as deep, and not much louder. Oh yea, this is w/ 5.5'' removed.
