decat with a straight through perferated centre and back box

I have a system which you can buy. It took me ages to find the perfect sound it has a magnex decat, powerflow centre box and longlife backbox. 2.25 rolled tip very inconspicuous sounds amazing not too loud but lots of burbles and it pops and bangs too

In most cases you loose mid range torque with a decat but gain a bit top end.

0.3 of a second is literally nothing that's more than likely down to your start, different tyre ware, temperature I would call that the same time proving decat made no difference

Mine definitely revved out harder and sounded crazy, but lost a load of midrange and was definitely slower overall - much better car overall with a cat

My decat and Magnex does no favours for me as daily/ragging about.on track you can keep high up in the revs so fine.
