My exhaust system is part of the problem with full potential. Shorty headers, Sanderson DD9’s, 2.5” collectors to 2.5 pipe, X-connector, dual 40 flowmasters.
Agree. I'd like to see a full length header, and 3" system, but I certainly understand the difficulty with that in an early A.
I ran a 2" header and 3 1/2 exhaust on a N/A 408.
