Cobra performance was interesting according to what engine was fitted, a Rover V8 gave what I'd say was akin to a Golf GTi of the time, Yank V8's sound lovely (far nicer than a Rover V8 due to a different firing order) but are a minefield to find out what exactly you have as the same small or large block could have come from say a Corvette or a camper van with totally different power output/characteristics and as the shape of them varies wildly to get an exhaust to fit you really need to take the car to have a bespoke exhaust made at quite large expense. It was for these reasons that I took the V12 route, power in abundance pulling away in top gear effortlessly and with the side pipes it sounded like a Spitfire of the Supermarine variety

Side pipes are all but essential with a Cobra as the floor is flat so exhaust pipes have to sit below the floor resulting in having to wind up the suspension for ground clearance whilst still running the risk of grounding, at night a quick blip of the throttle and flames could be seen emitting form each side pipe, childish but fun
