I think it's 2.25" from turbo back. I think they didnt change till the like 87 to the 2.5"

On my 89 Spirit 2.5 Turbo 1, it has a stock 2-1/2" pipe back to the gas tank, then it goes abruptly down to 2-1/8" (or so), and then just in front of the axle it drops to 1-7/8". Very poor.

Kyle, you could have just asked me or shawn, yets its 2.25". If your going to change, I know quite a few people just recommend the 3". Might as well do it right when your doing it. If your going to do it, lemme know. If we order ours together from cindy, shipping will be cheaper.
