Glad I located this forum. Great information. I recently purchased a 1969 Dodge Dart GT. The 225 was built several years ago as a performance engine that was drag raced. After the engine was toast, the car sat for several years. The car was purchased by the previous owner and the engine completely rebuilt to the performance specs. I am trying to get in touch with the engine builder to get the specs on the rebuild. Cam, Crank, pistons etc. The car has a single header to a single exhaust. I am planning on installing a 2.5 exhaust connected to the single header. I am trying to decide which mufflers to install to keep the great cam sound and the car not to sound like a rice burner when accelerating. I am leaning towards the Pypes Street Pros as they are made in Pennsylvania and I can return if necessary. Other choice would be Magnaflow. Does anyone have any experience with the sound and performance of the Pypes Street Pros or can recommend a good sounding muffler for a 225 that includes performance?

Thanks for any direction

I like Jones Exhaust Full Boar Quiet Tone mufflers. Nice sound but not too raspy or boomy.

IMHO, dual exhaust is for V8s. You will gain no performance advantage over single exhaust, and it adds weight to the car. Only for looks... 2.5" single exh is good up to somewhere around 225 HP, and 3" way above that. For reference, a true 225 HP @ the crank will get you around high 14s in a 3000 lb car.
