That down pipe will fit the 84 - 85? i thought it was only for 86 - 87's?

this downpipe is made specifically for our 84-85 GN's...it's 2 1/2 inches as opposed to the stocker which is 2 1/4. Also, it's mandrel bent instead of just "kink-bent" to allow better airflow...
Hope this helps.

A 2.5" DP is fine but you need to look at where you want to end up. Too bad Lee Thompson doesnt' still make his 3" TH style pipe. I have that one and there was a noticable difference in spoolup even over my 2.5" pipe. I think getting rid of the stock restrictive elbow is almost as important as the pipe.

I want t be running 11's by end of summer... im assuming that this down pipe will work for 11's?

I'm sure it will take you into the 11s no problem.
