OK I need a little advice. I am considering adding a couple of mods to my 2004.5. I would like to add either the EZ or Banks module and if anyone has some great pros and cons between the two I would appreciate the info. I am also considering upgrading exhaust to 5" but have heard some bad stuff about too much noise and not alot of perfomance increase over the stock 4".

Thanks for any help

 

If you are going to do Mods, then the first thing is gauges!

 

The most restrictive part of the exhaust is the muffler so youwill get plenty of benefit from repalcing the muffler with an Aeroturbing kit or other high flow muffler. For the type of mods you mented, you don't need a 5" exhaust, stay with 4". As for the box both the EZ and Banks work well, Banks does have the advantage of being adjustable on the fly and yields a higher power level and of course don't for get the gauges, Scotty RA3 intake and Turbo Air Guide (TAG).
