Would be interested to see the results of a wicked system like that.

Any pricing would be appreciated as well.

Thanks

as a matter of fact i just had a dyno done tuesday. afr was a little rich and the operator didn't start the runs until around 3500rpms for some reason so...

480hp/516tq at the wheels on a dynojet.

there's probably another few hp and 40lb/ft of tq still on the table with the proper afr and starting the run a 2k rpms.

i finally got some 1/4mile times tonight. this was a last minute thing at firebird raceway in phoenix (elev. 1,243ft) so there was no prep, street tires at 36psi, no ice for the s/c, temp 74f, a near full tank of 91 that was topped off at the track with 3 gallons of vp.

et: 11.90
60ft: 1.77
mph: 116.83

i did have a couple of passes at 118mph but 60ft times weren't as good so et suffered. traction was hit or miss...punch and pray. very first run was with no burnout and esp on at 12.3 @ 117, the rest were with esp off and 1-2 second burnouts. most times were 11.9's with one 12.0 ranging from 116 to 118mph.

Any cel lights ? If you can "mass" produce these you will sell bundles ... I am in for one ...

What other mods you got ?

my car is k2 (pulley and ecu) with my own exhaust.

it will throw a cel even with the o2 sensors relocated but the secondary o2 sensor cel was programmed out with k2 software.

just getting rid of the stock components attatched to the exhaust will save weight. the oem manifolds, cats, and resonators are HEAVY!

Why would the car throw a cel fault if you still have your front cats?

because of the location and orientation of the O2 sensors post the primary cats.

i don't really have the front cats. they're closer to the secondary cat location and i don't believe they get hot enough to allow the o2 sensor to pick up the correct info.

With the whole new exhaust system like this, don't you need to have the ECU re-tuned?
