338 and 433 gpx pipes?

[Snojet Steve]

I would like to know for sure whether there is a difference in the stock GPX 338 and 433 pipes. If there is then is it possible to use 433's on a 338?

Thanks.

No you cant. 433 pipe to much volume for the 338

How do you tell the difference, I have 2 sets of stock pipes? wondering

The pipes have 443 r or l stamped in them near end of pipes same for 338

I just drug home GPX #2 but all I have is 433 engines and pipes so far anyway. I think I may as well make it 433. Thanks for the info!
