You can get close to that side exhaust look while running the exhaust under the car, there is a perfect gap for it each side.

The motorsport rules are

5.2 Exhaust system:
(1) General Requirements: All vehicles shall be fitted with an efficient and effective silencer that:
(a) Ensures noise emissions do not exceed 95dBA (refer Part One Article 3.8), and
(b) Is securely mounted to the vehicle, and
(c) Is isolated from the cockpit, either beneath the floor or surrounded by gas tight ducting, and
(d) Ensures all exhaust gases exit the perimeter of the vehicle behind the mid-point of the wheelbase except where an allowance is granted by MotorSport NZ and noted in the vehicles MotorSport NZ Logbook.
(e) Does not protrude more than 150mm beyond the bodywork.

a little more progress on the tube front. I tacked in the vertical bars to support the top tube, ignore the welds there just tacked with my crappy gassles mig ill tig it at the end. made one cock up were i made a tube to short but when its fully welded with the spacer you will not be able to see it.

so just mount the headlights and bumper to go

so i have been waiting to finish the tube front because i ran out of argon. in the mean time i got a plenum i was planning on cutting up and trying to weld closed unused ports but i decided to polish it up. i might hang it on the wall for a later project or sell it
