What kind of pipe would be best for a ATC250SX. My friend has a 300EX with a cobra pie on it and it didnt help much. I can keep up with him With the stock 250SX

 

Cobra is the only exhaust i have found so far. i have been looking for a few months. i have a guy who will bend the pipe for me so i can build a custom exhaust. i am either gonna use an fmf titanium 4 or a megamax 2. thats the only other route i have found. my best advice, go to google .com and type in Honda Atc 250sx exhaust. i did that one day and got like 80 pages, but had to leave after only getting to the 3rd page. hope this helps.

 

Thats what my plans were.
