Hi I've got an 99 SR model and the backbox is rusted to the point it is leaking. I'm wondering if I'm able to replace the backbox with a GT model backbox with it being able to just bolt straight up to the existing stock exhaust without modifications?

From what I can see they look almost identical but the GT exhaust looks a bit nicer

Here are two listings on Ebay:
GT: www.ebay.co.uk/itm/264395903883?ul_noapp=true
ST: www.ebay.co.uk/itm/254723597905

If so, will this hold true for aftermarket parts as well?

Thanks for any help.

The pipe diameters are the same aren't they?

I think as a whole exhaust system it's easily interchangeable but as for individual parts bolting onto another system I'm not sure but I don't see why it wouldn't.
