I have found a nice set of CMI e-tops but i need a few of the brackets all of which i can purchase. Not sure if i will need to relocate the shift cables and ECM for this installation, the CMI install guide shows they are required but a couple of the big name marine supply shops have different opinions. Anyone done this installation before? My engine is a 03 model 496 Mag.

your wasting your time and money,,you wont see a increase in power unless you add the 525 kit..

i have read that many times... i like they way they look and sound and this is the first step of my upgrade. i just happen to have found a good deal is the only reason i'm starting with the exhaust.

Are they for a 496? or are they for a standard big block? I dont think they are interchangeable.

They are for the 496 i sent the photos and measurements to CMI to confirm they were correct and for the standard 8.5" riser.

I have a brand new cmi shifter relocation bracket i'll dump on ya cheap. It's a nice looking part; well made. If you're interested I can send a picture to your email. I don't have ability to post pics on this site. if not, have a good summer!
