Supersprint backbox?

[shantybeater]

A while back I managed to buy a second hand supersprint backbox, I've heard there are two versions, street or race? and depending on which one you get one of them is made of mild steel and may restrict cars over 280bhp as its only a 2.5" rather than 3"? (mines an IHI so would be no good if its the 2.5)...so does anyone know if this is right & which version i've got? i'm happy with my current setup but wouldnt mind slapping a nice oval on the back:

I looked on their website which is shocking & had no pics that i could find

urm its not hard to find out if its 2.5" or 3".. just measure the pipe diameter before the back box... (not very hard)

yeah true but i'm not sure if i'm actually right so hoping someone will clear this up for me

I had this on my beeza, just had it replaced with a blueflame system. You have the 2' version as its the black pipe work. Its called the strret system. The Race system is the bigger one with all staineless steel. They are not easy to get hold of. think motorsportworld sell both systems.

ahh right ok i'll keep my current system then for now...wasnt too keen on taking bits off my SS system anyway. Am i right in saying this will fit onto a standard system?? so if i were to sell it and the owner wanted just the box it would strap right on?>

 

[cupramillo]

Yeh i think it would fit straight on no probs. I got my SS box box for sale in great condition

By the way shanty, you're keeping this IHI a bit of a secret aren't you? We want a thread started son!!

hehe maybe i'll start a thread at some point...probably when it goes in for uprated internals
