Putting in the hedders going for true duals what is the best size to go woth on my pipes. I have heard a lot I will go with 2.5 if I have to. I will run an H pipe because I do not have time or space for an X pipe. One other question imports use a tube style cat and they are cheap I will gain clearance if I use these are there any drawbacks besides they are import racer stuff and I migh get flamed. Seriously will they be adequate and not make any lame noises etc. The hedman seem to have good clearance and I hope all goes well. Thanks for any input. One last thing anybody due this and will I feel a noticable difference. Since my Y pipe was cracked it has to be a lot better because it was driving like a 4 banger and souding like a diesel truck!

I just got hedman long tubes and I am going with the 3" to 2.5" reducer for my true dual setup. I seen others use 2.5" on there cars with dualz and it sounds, looks and preforms great. From what I've heard your good to about 400hp with that setup.
