New Exhaust...

update image

Perusing the images of the Engine and Chassis dyno results will reveal that 167 HP & 118 FtLb went missing when the engine was installed in the car. The key additional piece of information is that the headers used on the Pump had 1.875” primaries and the ones in the car, used on the rollers, are 1.625”. The rest of the current exhaust is a 3”-in/2.5”-out X-pipe with Flowmaster 2 chamber mufflers. Sooo… it’s currently receiving a set of 1.75” to 1.875” step headers with 3.5” merge collectors, a 3.5”-in/3”-out X-pipe with a pair of straight through Borlas dumping in front of the rear axle.
