I'm finally breaking down and spending the money to fix my 250R. I just orded an all new bottom end, and i'm hoping to get the project on its feet by the end of summer. They guy i bought it from gave me a cobra 2 stroke atv exhaust pipe with it, but i'm not quite sure how well it'll work. Actually, it's shaped similar to the ATC pipes. I know how much power gains can be had from a pipe upgrade, so i was wondering what pipes i should look into? Right now, I'm considering the ESR trx 5 and the LRD all-around pipe. I've heard great things about both, but need some help? Which do you prefer? do you have any other options? i'm looking a great all around pipe.

 

I would have a hard time picking between the ESR 5 and Curtis Sparks...

 

Get the TRX-5. LRD had good low to mid but didn't like to rev. Sparks isn't making 250r pipes anymore1 Iv'e been on there waiting list for at least six months now.

 

Im just wondering, how do u change the top end in somthing.
