I am running a supercharged 6.2 litre LSA in my alloy-chassis Australian-made Pace 427SC. I had a custom made 2.5" stainless under car system with mandrel bends fabricated to fit the car by a local race shop that does work for some Australian V8 supercar teams.

My Cobra's design is a little different in that the exhaust can be located each side inside a frame rail channel on the outside of the car (but under the body). From the side of the car, you can only see about 10mm of the exhaust as most of it is tucked up into the channel. I am going to get that part powder coated in matt black. Had I run 2.25" tubing you probably wouldn't have seen it at all...but I needed the 2.5" for flow with the blower.

The exhaust runs into 2 x high flow 2.5" mufflers concealed under the body and the tips are turn-down type which sit flush with the body and are not visible from behind the car. Clearance is tight, but it all fits.

I am also running catalytic converters in the car as well just after the 4:1 headers so the system is fully emissions legal and tested/complied as such.
