hi

i got a guy that crashed his RC51 and he said the mid pipe has some rash and a small dint but ok. there jarldine header back 2-1 and was worndering if the header will fit or what it would take to fit one on my 98 superhawk


any one done this and did it help perfromance? dit the lower chin still work??


thanks for the help ill let you guys know what happens

 

They don't fit. BTDT Close but no cigar. If you have a pipe bender, then maybe.

 

what was off on them? on the engine or the tail? do the headers fit in the head? was the engine rake off? i saw a post of yours bling that you posted a wile a go but you said you put it on the back burner. so i guess it still there lol. i just want to know what I'm getting my self in to because he selling header back and can for 50$ i can get a cuter and welder and just use it for a custom exhaust i guess if it all bad. i just want to know your experience thanks

 

All though both engines are 90 degree V-twins, the physical size of each is different. The port sizes do match up but the length of the header is a good ways off. You'll probably need to cut/weld (best) or bend (worst) to fit the rc51 headers to the superhawk motor.

The exhaust tube diameter is also bigger so you'll want to run a full 51 system, not just the headers.

 

how did the rear match up? that my big consern

 

You'll need the RC rear down tube to match for best flow. I tried using the 'hawk's downtube also but it was a 1/2-3/4 inch off from the header. Way too far to try and muscle into position (yes I tried, boy did I try.....), so you'd need to either get it bent or cut and reweld.

The rc tube ID is larger than the VTR. I suspect this is for more flow due to the higher rpm ceiling of the 51 and might actually be detrimental to the VTR's powerband. Of course, you won't know unless you try and measure it of course. The overall design is very similar to the VTR but the exhaust mounts are different and very far off.

 

i see well thinks for the help i might just scrach this then im just trying to get a better sound but would love extra hpssss thanks for the help
