Te 510 header

Does anyone make a performance header for a TE 510?

Hmmm. Not sure what ya mean. Are you looking for larger diameter headers-meaning the pipes that bolt to the cylinder? Or do you mean an exhaust can? Something else? Just trying to be helpful.

Yes larger diameter headers

Larger diameter headers would mean less back pressure, less low end response, better response way up high. Given the size of the exit, there is limited options to go larger, without some major surgery.

Larger valves and a more aggressive cam grind would help.

As far as i know, nobody makes this. Most guys need the 'hit' and so keep the stock sized headers.

You could easily have custom headers made up. Ive done it for the 510, but i wasnt after changing the power band, i wanted a different length for scavenging and for fitment. Its a little tricky with the frame--it was designed for the 450 barrel--but not that hard to do. The '08 frame is easier.

I payed around $100. Its no big deal for any pipe bender/welder. Only tricky part is the collector-i got lucky and found one pre made. Check with Uptite--he might have more info.

Maybe 'tard guys like CH or GP would have info on this mod?

Just trying to help. Its an unusual request.
