Hey guys how are you all doing...
I would like to purchace a turbo downpipe for my 05 legacy gt. Its automatic/automanual......
I noticed on the stock downpipes there are two(2) catalytic converters
The aftermarket down pipe im lookin to purchace is made for the automatic legacy but has only one cat from what I can see
Its the INVIDIA brand
which brings me to my question
(WOULD I THROW A CHECK ENGINE LIGHT IF I PERFORM THIS MOD?)
(GOING FROM 2 CATS WHICH IS THE STOCK PIPE, TO A 1 CAT AFTERMARKET PIPE)???
any help would be greatly appreciated
