Hi Chaps,

Could someone tell me what the inlet diameter is of the standard tezza backbox?

Much appreciated

Uffan

inlet diameter meaning the end that connects to the cat or the other end at the tip of the exhaust?

Basically i'm after a backbox so i want to know what diameter the inlet (on the backbox) should be.

Thanks

i wouldnt buy anything other than an Altezza specific exhaust, wont make any difference performance wise and will sound like a moped screaming down the road!

Hmmmmm, but the standard one is so quite, i just want something that is abit beefy

the IS200 has the same back box as the RS so it should make it a bit easier for you to find 1
