Aaaahhhhhh, check your facts, page 96 in March of 2001 issue under the conclusion at the end of the article, they chose the White Bros. E-series as the winner. Just stating the facts!!

 

I have a complete Curtis Sparks X4 pipe, in like new condition, for sale for $300. There isn't a 400 with any of the above mentioned pipes that will be able to keep up with you.

 

no exhaust makes 18hp, bs. The best pipe is SPARKS X6 or go with HMF FULL.

 

i think i whould get the white brothers e series!! very loud and great performance
