I looked everywhere and could not seem to find the answer, so im hoping some you guys may know. I have an 08 base with single exhaust. I recently went to the junk yard and found a 98 monte carlo with a very clean dual exhaust. I know the cat back from the monte wont fit on my gp, but will the "y pipe" on back fit? Im 50% sure they will but wanted to see if anyone else knew for sure.
