From what i have heard, the HMF is the best. Not sure though, and as for the LTE it seems kind of heavy IMO

 

Thanks everyone for your input I think that I'll go with the hpd pipe I've heard alot of good stuff about it.

 

be carefull in buying from Hpd, they have always been great with the scrambler stuff but they suck when it comes to the predator.I wouldn't trust a pipe from them no matter if it was for the pred or the scrammy.I had their race pipe for the scram and it fell apart/cracked everwhere.although I don't know about the pred pipe,but i can tell you this, they have dropped the ball lately with me.do a sreach here on hpd ,you might find a post on them, from me about my problems with their products. they screwed me good when i was modding up my pred.I still like the people there ,and they have some good things,but, everything I got for the pred from them had to get modded in some way.
I got the rath racing pipe.it is great.it looks much better,and is stainless steel. also Dayrl Rath is the man when it comes to the predator. after all he did have a big part in the design of the predator.He has been racing them from the begining and he and his wife a very nice people,who will go out of their way to help you.
