Well my mate is mot tester and he used to drive ukdm DC2 himself
He was like **** this **** man just put dcat on it i pass you anyway hehe. But once you do 100+ miles with N1 you dont want it to get louder thrust me
I still have standard cat that 'barely' passes mot anyway its so worn lolz. I can drop that in anyway for free at my mates if i need it lolz.
Next thing will be probably ODYSSEY PC680 battery
With kill switch.
Since I drive itr 2 times a week battery dies all the time. I got allot of static power drain --> car alarm with them motion sensors, car stereo + amp, Defi dials ect. And for last few weeks i just keep my negative terminal off the battery.
But for 110f i can get one of those and shave 6kgs off the car. And that is as much as you save on carbon **** lolz.
ps. -Ad----> Jazz jets i need to get some !!! Got myself 40f wipers some better jets would be good
Ps2. Since last mot in April till one in January my itr done 1834km barely driven lolz.
