so i need a pipe for my s3 what do you reccomend i would preffer to not have to buy a pipe my choices are between a jp1 and a jp2 i have a msr1005 but its on my p5 in my jammin buggy and i hope to leave it there. so wich would be better for this engine jp1 or jp2 Thanks
Im sure its a powerful mill, If I was you I'd try the Jp1 first, if it was too much bottom for indoor, I'd switch to Jp2, but you may even be better off with a 3 as an overall pipe , or a 4 has a bit softer bottom end. Thats my opinion, there may be other options. but I was just trying to suggest whats at your disposal.
I have a RB s3 and did not like the JP1.. too much bottom indoors however I did like the JP3.
I do curently have a RB2045 on it and it is very smooth with excelent run time,but lacks a little bottom which can be fixed with a clutch spring adjustment or header.
