Not on an LSx engine, if you know what you're doing. Lots of cam-only C5s.

Having owned 2 C5s...while drooling over the modder's fest this forum provided...When I purchased an 04 GTO for CHEAP, it was with the fullest intention of doing all the stuff I missed.

I intended to be smart about the mods though, maximizing gains for investment.

I added a set of Z06 #243 Heads (unported), CC 921 springs and an LGM G5X-3. I took it to Lou's shop and we spun the rollers to 369 / 343. This was with Lou and I working the HP Tuners. Straight-up the car felt lazy and strained. All this time we were blowing through the stock cats and iron log manifolds.

A few weeks later I ordered up SW headers and RT Hi FLOW CATS.




The car CAME ALIVE!!! SWEET JESUS!!!

Granted...you are considering a pretty mild cam for the LS2...MTI Stealth. I would seriously consider the headers and cam to go together. I don't think you will lose anything on the cam, but I think the results considering all the labor could be lackluster.

You are spot on... don't have the specs on the cam, but it is the small 21cmc blower cam...

Went with the Kooks with cats from Tbyrne. I will install them with a buddy at the base autoshop. I think it's smart to free up the exhaust before a cam. Next year, I will go with a cam of some sort.
