I am sure on a thread like this, you will receive several different opinions. I have only tried the Jammin' 3 and 4 pipe and loved the JP-4. It gave great performance and fuel consumption.

Only way to know for yourself is to test em...get the motor and spend a day testing and tuning.

i am under the assumption those are the pipe you currently own.

The JP-4 seems to be a pipe of choice for a few, from what I understand very underrated. I know a follow racer who owns a Hobby shop and Dyno. He is always experimenting with pipes and headers, he mentioned that the JP-4 has loads of top end and excellent fuel mileage on a open sweeping track, better than most pipes currently on the market.

I really like the dyn 053. It has a nice wide power delivery & good fuel milege. I run it on my jpx & trinity extech. Good all around pipe.

The ] shaped headers give a little more back-pressure which increases bottom end performance a little. The Dynamite pipe is good, but the Ofna 053 is better.

Stick with the Ofna..The Jammin engine does not need any help with top end..It screams on the top 5+2 ports. You want the little extra bottom the double bend header gives you ], or you can deal with the dynamite and gear it down to get the extra bottom torque. That's gonna rob you of some top speed though
