i was looking to buy a hks hiper piping with a skunk 2 exhaust from the cat back. but i was wondering if the non gsr cat is shorter then a gsr cat. the exhaust is coming off of a gsr da.
SO THE QUESTION IS IF I PICK UP THE GSR CAT BACK WOULD IT FIT WITH MY STOCK NON GSR CAT. IS IT JST A BOLT ON OR DO I HAVE TO DO SOME MODIFICATIONS?
