ok i just picked up an 85 gsl .. i am thinking about taking the exaust off it and putting it on my 79 .. my question is if i take it from the header to the muffler , will it all just bolt in . or will there be different hangers and and stuff.

 

The 79 'Reactive' system is quite different from the 85 'Catalytic' system. But if you're running headers with the right flange and no emissions, it should work.

 

i have a 79 that is 100% stock .. i have a 85 with a full racingbeat system ... am i going to have emmision problems
