Iv got 2 half inch system on my 03 sti the second gasket back has gone but I'm pritty sure the gasket is different to the standard sti exhaust could anyone clarify this for me thanks

 

Up

 

Centre to back box. ? If so prodrive and Sti exhaust have the same gasket.

 

Other than the joint with spring loaded bolts i think they are all the same. Have a look on import car parts web site, they do the genuine ones with new bolts and nuts which are a lot better quality than cheaper ones of ebay.

 

Centre to front I'm sure thay are different , last time sti wouldn't fit the holes on the prodrive one weren't directly opposite and the down pipe is prodrive.
If I remember correctly
Myself and graham good had a problem getting one

 

There's no difference at all, unless you have an aftermarket Downpipe. ?

 

Prodrive sport cat ??

 

Possible that I might of had the down pipe gasket changed before and that's the one that's different

 

the 1st to 2nd Cat gasket is the same on all 01-05 cars

the Hawks are specifiaclly different

 

Ill fone you Tuesday to order one
