I have limited space in/under my car and would like to use the space previously occupied by exhaust/muffler for Charge Air Cooler components. I see rules governing exhaust as below.
15.10.I. Exhaust manifolds and muffler systems are free, except that they
must be quiet and terminate behind the driver (Section 3.3.3.B.15).
3.3.3.B.15) Exhaust must exit behind the driver or exit to the side of the car.
First off, which is it? Must the exhaust exit behind the driver or may it exit to the side of the car in front of the driver?
Secondly, If exhaust must exit behind the driver- I would like to use side pipe exhausts below the doors/rocker panels, but would this be construed as being in conflict with the below bodywork regulations?
15.2.I. Spoilers/splitters and cosmetic trim pieces are permitted. Side skirts may not be used.
By necessity of desired cross section area and space constraints the side pipes would be likely be 2" tall by 6" wide (wider if it ends up requiring muffling) and rectangular. I could see how they are starting to look like they would function as (not allowed) side skirts.
What say ye, fellow Street Prepared competitors?
