Hey guys so I've had my hdi for a day or so now and was just wondering if there are any free/cheap mods or little changes that can be made to make things a bit better?
I have a straight pipe back box replacement from my old xud that can go on and a few different air filters to choose from, is there any major problems other than heat soak from running an open filter? Im having a day of tinkering and getting to know the car so any help or advice would be amazing
Thanks
