At the moment yes, but to be fair I haven't tested like for like, we tested a straight pipe and not de cat pipe in the shape of the Janspeed cat.
The only way to test it properly is buying buildin a de cat pipe the same shape as the Janspeed cat.
I must point out that this is what we have found with our car, what it'll do on your own is another matter.
We'll be testing another exhaust theory hopefully today.
We have over 70 passes on the dyno in the last couple of months testing different combos Slicks 11.77@115.92mph Street tyres 12.162 @ 119.02 IT'S NOT HOW MUCH YOU SPEND BUT HOW WELL YOU SPEND IT |
