Im just wondoring if anybody has bought one and if it was worth it or not?

 

If your 250sx is stock, and you don't need to worry about a spark arrestor then yes. You will need to rejet and I also recomend a high flow air filter like a No-toil or UNI. Remember an engine is essentially an air pump and the more air you move trough it the more power you will make.

if a spark arrestor is something that you can't overlook, then see if you can get your hands on a supertrapp unit. If that is not enough for you, then XRs only does custom exhausst systems that may suit your tastes.

hope this helps

 

I did get a k&n air filter for it. get this when i got my 250sx from my grandfather it was missing the spark arrestor cover and I made one for it thiking it would change the pitch of the sound and i think it added power?

 

if you ride in dusty areas, then get an outerware, the K&N does not filter as much as one would hope.
