No problem...

For the intake I am currently sourcing a new sleeve that needs to be custom made for the connection between the airbox and pipe. I should have my sample very soon...

The rwhp gains we posted for the intake & exhaust seperately were done purposely, to show the gains for each part. We haven't had the opportunity to bring the car back to the dyno for more testing. But if I had to guess, I would say no more than 25 rwhp.

Seems like the baseline numbers of 333/327rw SAE are quite low compared to the other stock dyno's we've seen.

This was done on a dyno jet with 91 octane gasoline since it is located in California and in 70-75 degree weather.

Believe it or not, the IS-F is louder than a Z-06. I drove them back to back, and the IS-F is a LOT louder with the stock exhaust. My friend said it makes his Z-06 sound like a Lexus.

If it's louder, then it's not going to be my cup of tea. Damn.
