Hey just looking for some advice on people's expierience with the jp4 on both OS Speed's and standard os v-spec's.I have seen a few pictures of pro drivers cars with these's pipe's on their speed's, and was wondering how they perform?

I have tried a OS 2050,2060 and a TTR 2035 on both my OS Speed's and standard vspec's and they have all been fantatstic.My personal favorite is the 2035, its also about half the price of the OS pipe's.It would be great it someone could tell me if the the JP-4 is any better/worse than any of these pipes.I also would like to know how the jp-4 affects power and runtime on the motor's


Thanks heap's

i have a friend who runs this combo and loves it.. he likes the way the jp-4 smooths the power out for an all around good feel..

Thanks for that mate, does he run a speed or a blue vspec?

I have it on a Speed and a regular V Spec. I won't comment on the regular V Spec as it has less than half a gallon and I'm still breaking it in but it is nice.

With the speed I had the JP3 on. I liked it, had tons of power and was getting over 9 minutes of runtime. I put the JP4 on and it did take away some of the bottom end but all it did was make it smoother. Still plenty of bottom. It definatley tamed the middle down , and has killer top end. Within 20' I'm pulling on guys going down our mini straight. And my runtim went up. I'm probably pushing almost 12 minutes with the Mag head Speed and the JP4 on my RC8 with stock clutch set up.
