Hi Guys i had my DE remapped last year with Japspeed, De-cats, Y-Pipe and a K1.
I've just bought a HR standard system, i aim to keep the decats but run the HR Y-pipe, cut out the silencer in the center pipe and run the standard backbox.
will this cause me any issues in terms of the map and peformance or restrict it at all? I know the HR y-pipe is alot better then the DE, but is it better then a Aftermarket?
would I be better off keeping the Cats and Y-Pipe and just changing the centerpipe and backbox?
Thanks in advance!
Jason
