TSI and TDI catback exhausts interchangeable?

Featured Replies

can anyone definitively confirm the catback exhaust from a TDI vRS will work on a TSI vRS?

 

i have an apr catback at the moment, and looking at returning it back to stock.  i'm keeping my apr downpipe.

 

my mate (with a vRS TDI) offered me his stock exhaust, however i noticed his middle resonator box is tubular.  i was expecting it to be more rectangular/squarish though.   hence i'm confused now.

i understand the downpipe to b different between the TDI and TSI, but i was under the impression the catback would also b the same between the TSI and TDI - however it does not seem to be the case.

 

even the muffler itself seems slightly different.

 

or am i just being too padantic?!?!

 

anyone?
