It was great to meet Swoop and his father yesterday and we appreciate the use of his truck. :waytogo:

The stock baseline was 323 RWHP / 343 RWTQ. We then installed the Corsa exhaust system and put the truck back on the dyno. The numbers with only the Corsa exhaust were 333 RWHP / 351 RWTQ.

We then installed an Airaid CAI and our custom dyno tune. This combination made 353 RWHP / 369 RWTQ.

I will let Swoop comment on the way it drives, but I thought it felt great. I got some video of it on the dyno and a little test run on the street (sorry for the quality, it was pretty bouncy and I couldn't keep the camera steady).

If you've still got the factory muffler in your possession, would you please give it a look and see if it's a straight-through design? In other words, can you look through the inlet and see daylight through the outlets? Would really appreciate the assist. The answer might explain the 10 hp/8ft-lb difference between the factory and Corsa exhausts, and will help me decide whether to go that route.

You cant see directly straight through but if you hold the muffler at the right angle you can catch a bit of light from one of the outlets. Its very "free flowing" for a stock setup. Benefits of a aftermarket muffler are going to be mostly sound. You may get a few HP but I would attribute the 10 hp difference to dyno variance between pulls. Unless they did several pulls in each config. and took the average.

I didn't bring the stock exhaust back to Florida. I'm sure Livernois could help you out since I think they got three Raptor systems laying around. :)

They did about 10 pulls on the truck. I gained 9 with just the intake and no exhaust/tune.
