I saw that there were some comparison's, but I wanna get some opinons on all three. What has been done to your car and what do you think is the best mod for the money. I'm kinda leaning towards mid lengths with an o/r X. What would be the difference in H.P. between mid lengths and long tubes? Also what would be the easiest to work around (mids vs. LT's)? I work on my own car and would like some input from people that do their own work also.
