Kept nothing from my stage 4. I'm sick of collecting crap I don't need.
The car came with a Y pipe and I was given the cats by the last owner, which I fell over in the shed.
So they've gone in the bin too!
Have kept my OEM exhaust as was going to refit it before selling the car but im having more mods done tomorrow so its likely the car will stay that way now. Oem parts will probably just gather dust in the garage and be offered with the car if and when i sell it. Thats a big 'if' though
