Exhaust fitted today

<< < (3/3)

cooljimy84:
The only way to prove it would be to put the old one back on the car and see if it goes slower again. I think as said before that it may have been a lazy sensor at some point, which then fixed it's self in removal and refit.

Also i know that the intake system is sensitive to airflow speed, if your in take sensor has a too big pipe, it can't measure the in coming air accurately. Could be the same for the exhaust...

Or a dirty sensor, that got cleaned up on removal ?

I belive the less backpressure the better on a turbo car.. Maybe not the case with a smaller k03 turbo though..

When i removed my milltek for a straight pipe coming out under the side of the car with 1 silencer i felt gains.. Allthough i belive the milltek restricted my car

chrisvectra:
The old exhaust has gone in the bin bud so couldnt do a back to back test on it.  also there wasnt any sensors to remove from the old system  so I dont think its sensor related either..
I have spoken to the powerflow guys and whilst there not 100% certain they think it maybe back pressure related..
