WOO HOO! Exhaust is coming today! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Yessssir, thaaass right! My Hooker Maximum Flow Mufflers (2½" In/Out) will be here today, as well as my Hedman Header X-tensions that I ordered (Mandrel pieces to clear the tranny crossmember)
I'll probably take the truck over to the exhaust shop at lunch and drop it off. I'm also having an 18mm Anti Fouling Adapter Plug welded into the exhaust, just after the drivers side header collector. Reason being, a friend of mine has a Wideband O² Sensor, and he's going to help me tune my carb for idle air mixture and for WOT/Cruising air mixture.

Yipee! Now I will finally get rid of that annoying rattle caused from the EFE Valve.

Tim,

everything sounds great except the location of the bung. For better readings, it's best to install it in the header collector as close as you can get to where the primary tubes come together.

I'm going to install it directly behind the collector, because my collector is about 4" long, but if you look in it, the 4 primary tubes basically extend half way in. So...I should be ok. I just gotta find something to put in there when I'm NOT using it. Will a normal bolt do the trick?
