i have Blitz BOV on my car and i have it permitted as well as my Filter and FMIC. on my permit sayd BOV not to be too loud hahah thast the funniest shit i have ever heard coz it is loud as f@#k. I went to welshpool. They didnt pass my pillar guage coz yes was chrome and the light reflection was the only problem. I taped it up with tape and toook it back over (they passd it) its all a crock of BS if you ask me. My car handles and stops better than most cars out there yet i still get yellows for mods even if they are improvements. But what can you do. Cops should learn a little about cars and mods b4 they go out in the world and tell us what is and isnt wrong.
