Curious too...for v81 that is. JB3, dp's, dual cones, stock catback and stock secondaries safe?

I have JB3, RR catless DP's, DCI, Code 3 FMIC and the system works great with no limp modes or any problems so far.........knock on wood......................i have V81 and 29.2+

Great setup! Definitely a lot of power there!

JB3 + DP's is a SOLID combo... tons of power, no problems. We have dozens of customers, both pre-29.2 and v81.

If you want to talk to an e90post member running v81/29.2 with jb3 and DP's, talk to "gimp2x"

i have basically the same setup with v80 and 29.2...
no problems here...but i am pretty sure you need the simms from terry to run catless dps. they only cost approx $100 why take the chance and not use them?

i have had my sims with catless dps since i first got JB1.

Our true 3" catless pipes would be a great addition to the JB3! PM me if you're interested!

+1 AR design best DPs you can get for our cars in terms of performance

fit well, not expensive, and work great with BMS o2 sims

fully catless here, no CELs

good luck.. jb3 is great also

[Brian-313]

Thanks for all the information guys

[Brian-313]

by the way , what is the O2sims we are talking abt right here ?
bare me :P i suppose it's some kind of bypass for piggyback ??

There are pre and post cat O2 sensors. When you remove the first set of catalytic converters the DME will detect this as catalyst inefficiency and set a code. The sims are used to fool the DME into thinking the catalyst is still in place. The sims are installed at the DME by extracting a couple of wires and hooking up the sim.

The sims are strictly for use with the catless DP's. They are piggyback irrelevant.

i have read good things about your dps, but since our stock exhaust systems are 2.5 inch, even yours need to taper down to 2.5 inches correct?

i have UR catless dps by the way.

thanks

That is correct. However we taper much later. UR is 2.5 all the way.
