Im thinking of getting a helix uppipe and downpipe..

I already read many post about the downpipe and will get that one but now I figure if I am going to get a downpipe might as well get an uppipe to maximize the gains.

so my question is

is the helix uppipe catless?

does it fix perfectly with the stock turbo?

If removing the cat in the downpipe requires a cel fix then do I need a 2nd cel fix for the upippe as well?

And if I am to fool the o2sensor with the fix, will there be any long term effect or potential issues or problems doing this? because the ECU will not be able to regconize how rich or lean im running and the car may or may not be efficent. Do I need re program the ECU, get a utech to monitor the change? Im just afraid if I do this something might go wrong down the road.

I know getting the uppipe and downpipe altogether is within my budget but if I have to start getting other parts to monitor my engine management then I rather just stick with say the downpipe.

 

thanks for the info.

so what is the difference between the resisitor and mil eliminator?

and if I do not put pack the stock EGT sensor can I use that bung for say my aftermarket Greddy EGT guage sensor plug? I do not know where to put that sensor, drill into the downpipe or uppipe or the exhust manifold. maybe I can put it in where the sensor is for the uppipe? think that will work?

thanks

also the helix uppipe is about 199.00 US, is the Gruppe-s uppipe as good because it is much cheaper or you get more power with the helix uppipe also it is a flex joint.

thanks
