I installed a set of BBK LT's and BBK o/r h-pipe on my buddies 03 this Saturday. I had a little help and with the k-member off it took 8 hours. I installed a set on my 01 so I was prepared for an easy install. But, I ran into a small problem. The top back 3 bolts/studs on the passenger side were a pain. I had the same problem with the JBA's I put on my 03 only it was the top back two. The problem is you can't lower the engine far enough to clear the frame rail. I didn't have this problem on my 01 because I could lower it a lot more than the 03. other than that it went very well.
We hope to dyno tomorrow and compare the numbers to what I got after the header install with minor differences. I have a dyno sheet with JBA 1 5/8 Cat4Ward headers, Bassani o/r x-pipe and catback, K&N air filter in the stock air box. I also have 4.10's. My numbers were 411/384 SAE. My buddy will have the BBK LT headers, BBK o/r h-pipe and Flowmaster catback with the stock gears. I'm going to put my K&N air filter in his car. This should be a pretty good head to head comparo. I think my 4.10's probably pulled 5 rwhp off my numbers. I'm not sure what the difference between the Flowmaster and Bassani catbacks is. I'll post the numbers when we get them.
He'll have to have gonzo big numbers over mine before I'll pull the JBA's off mine. I've done two header installs and a 4.10 gear install on my 03 and my buddies on 3 out of the last 4 Saturdays. I'm ready for a break.
