JBA Shorty and Mid Hi Flow Cats anyone?

[Hemi Challenger]

Has any one here put on a set of JBA Shorty headers and the Hi Flow Cats and mid pipes on there 09 Challenger RT 5.7 car? Want would you estimate the added HP to the rear wheels would be with this add on setup?

Unless JBA revised the design of the shorty they will not fit the 09' heads.You guys have the same exhaust port as the 6.1.so either run a 6.1 long tube or a stock 6.1 header.....which is a true shortie in the clamshell.....you should pick up 10-15 hp.

Im curious to about hp #'s, each seperatly are rated at about 9, but typically when you combine mods you dont get the sum of each seperatly installed.

I just installed the new “D”Port JBA shories yesterday and did a dyno tune. I had the high flow cats from HHP on it already, but have a baseline from before they were installed. Combined I picked up 15hp, and 42tq at the rear wheels.

Was it a big job installing your JBA Shorty's? Any tricks or snags to know before starting and how did your 02's fit on them? Plus did you SHUT off your Rear 02's through your Diablo? Thank you for the info.

I had a shop do the work, but it looked pretty straight forward. They didn't seem to have any problems, and did most of the job from under the car. Personally, I would not take on this job without a lift though, but one could do it without if needed, I think. All my 02 sensors are on. The headers and cats have bungs in them for the sensors.
