Thanks again SSSammy. I cant believe how leinient the rules are in Texas. No noise control just need an exhaust, no emmissions control (in McAllen),no filter issues, no chassis engineering tests, can do what you like to motor ie supercharger or nitrous, no wheel guards ie tyres can protrude past the guards.
Just need your lights at 24 inches and front seat belts. You can even have a cracked windscreen

yep says that in the rules.
Just roll up to inspection show the receipts for motor and chassis and 10 imn check and done one Aussie Cobra with side pipes and nitrous on the road for cheaper than the cost to engineer it in Australia. What a place.
