This car is full 3 inch exhaust. Supercharger cars are less sensitive to exhaust back pressure than a N/A or turbo car. On Charlie’s Riv we did full 2.5. Not exactly sure how much power we lost if any when we did that. I have not had a chance to dyno a direct 2.5 vs 3. I do know these engine move around 1600 CFM of air at full power! My cars will put so much heat into the exhaust the pipes are almost purple to the tips. So it gets very hot and grows 3/4 of an inch.
I’m doing a 3 inch so the system will live on track.
The reason I’m going to bigger mufflers that the system on Gunner with a stock LT4 it would not meet the sound requirements at our local track Waterford. So bumping the power from 700ish to 900ish I’m sure I’ll need more sound control.
I’ll bet this car will not meet sound also. But they do not measure on practice days!
On a side note my neighbor could hear Jackass 2.0 on the highway at WOT 3 miles away. LOL. These cars are loud at WOT.
