A lot of people seem to like the Jammin pipes and Im not sure why, a buddy has pretty much told me to completely stay away from them and he knows his .21 shizzle like mad From what I have learned, they are not fuel efficient at all, but the round smooth flow header is a great header to have but hard to find by itself, especially polished I think you could maybe do good with an Ofna/Dyn 053 and be good to go for both mills.........The Ofna 053 pipeset has a slight edge over the Dyn 053 pipeset performance wise, but they Dyn 053 makes up for it in durability.

If you're adamant on using a JP pipe then your best bet will be either the JP3 or JP4. Both pipes are all around pipe. The JP3 has a smidge more bottom end than the JP4, but the JP4 has more top end and better run time. Hope that helps.

I like the JP2 with my 421. It's not too heavy on the bottom. I did notice a little more run time with the JP3 though.

the jp1 is a torque pipe which could be good if you have traction and short straights and need quick acceleration. Good for a truggy also.

The jp2 is the opposite and will make the engine more mild on the bottom and easy to drive if you are looking for some traction and to tame down the wheels spin. It will turn RPMS like crazy if you have a long straight.

The jp3 seems to have just a bit less torque than the jp1, but is a good match with the V-spec. Still plenty of grunt, especially in a buggy.

I haven't run the others...

Just a guess but i am pretty sure it's because of the reinforced stinger and they are very durable

+1..My jammin pipes are collecting dust..if you have an 053. an 086, and an RE-11 (2050) its all you'll ever need and all 3 of those pipes will yield 2-3 minutes more run time than any of the JP pipes..I will say though for all around power and the smoothest powerband available the JP-3 is hard to beat

For the v-spec you will definately want the 3. The I love my JP-3 on my v-spec. It makes great power, with a good powerband, and gets excellent runtime. For the nova, I agree that JP pipes aren't great for them. Maybe look at a dynamite 053. Or even a dynamite 086. I hear those 421's are supposed to be bottom end monsters, so you might want the 086.

Forgo the JP get a dynamite or NOVA pipe you will get better run times and better power through your entire band. JP's are ok pipes if thats all you have at your disposal. The dynamite and NOVA pipes are actually about the same price or cheaper than the JP's.

Yup..when you get into the long heats, switch to the RE-11, or 2050 if you can find one..for the V-spec it will give you 2-4 minutes of extra runtime depending on your tune, and your trigger finger
