Well, sounds like you'll have some sort of deepness to it no matter which size you go with. If you are talking overall length I would go with the 30", if you are talking case/length I would go 24". The 18" may be right for you but I have not personally heard it before and have not heard good nor bad things about it.

I will be going with the 24" from Summit as soon as I get back in town and have time to weld it on.

If you are wanting a fairly big increase over stock then the 18" would probably be right for you, I am trying to get mine as close to stock as possible with a little bit of a deep tone at idle, therefore the 24" is the right choice for me.

Good luck man!
