Borla adaptor plates
Ok so I finally got the borla installed on my 88 Gta but It kinda sounds like poop at the moment I seen that the exhaust cat back system is suppose to come with adapter plates to flow the exhaust through the muffler instead of making it come out the exhaust cut out. Now I got this exhaust off a craiglist seller an I did not get the adpator plates with it. Where can I get these adpator plates or could I make my own outta thick sheet metal with different size holes in each plate ??? Just a thought
