I am trying to decide what size exhaust to run. I am going to get headers this spring. I plan on running a system close to the Spintech system. I just have a MP PCM and 52mm TB. Should I run 2.5" or 3" exhaust. This will be full duals.

2.5"... max. Or go single 3".

2.5 for duals or a 3 in single. How heavy are you going to mod in the future?

The truck will get lots of mods over time. This year will just be the exhaust and maybe a shift kit late in the year.

The 2.5" duals will support you well into the bolt ons. Go that route. :biggthumpup:

Yeah, the only reason I was thinking 3" was because it will not be mandrel bent pipe.

If you can do it I would definately spend the effort to go with mandrel bent tubing. I made the mistake on my V6 and didn't, lost some low end torque through restriction. I learned.... and didn't make the same mistake with the R/T.:goodluck:

The restriction should actually help with torque. Opening it up usually nets loss. I think the problem is the bloody 6 banger! :jester:

G'day mate, don't you ever do any yakka? you reckon it's the 6 banger, I think you c'mon the raw prawn with me. Fair dinkum when I installed a "blowmaster" on the original system I lost low end grunt, and after opening it up and shortening the system (side exit) I picked some back up. I reckon it would have been the opposite also, but the proof's in the pudin. I gonna extend it with mandrel bend sometime and ditch the "blowmaster" for a Magnaflow:nana:
