71DD340, you are correct Sir!

How much power is the engine making?
What is the intended purpose of the car?
What is the normal driving RPM?

Engine was dyno'd at 400hp and 400 ft lbs. 100% a street car, would like to run the track a time or two.

Lol normal driving is between idle and 5,000 rpm. (Occasionally) Normally if im just cruising i shift around 3k ish

Heres the current accurate performance muffler.

Heres the gibson performance mwa muffler. The difference is quite noticeable
