Your right again Snotty!!! I've always said GOd is a Mopar guy, I've never had a Mopar show rained out. One time it rained but it only lasted about 30 min. then the sun came out and it got HOT!!!

After thought here...in addition to the new exhaust system, I thought this would be a good time to locate and add a set of HP exhaust manifolds. Will the HP's line up with the standard 440 exhaust manifolds or should I get the HP's first before spending the $$ on the exhaust?

IF you can find 'em, get the hp manifolds first, because the outlets are at different locations than the stock logs.  That's what I have done so far...might go the TTI route next, or have an old salt muffler shop guy do up a system for me.

Yes, stock manifold outlets point straight down; HPs point rearward.

I really lucked out today!  Located a nice set of the HP exhaust manifolds with  the heat riser parts still working from a good ole boy, and he was only 30 miles from me.
I have been convinced from the replies to this post to go with the Dynomax Super Turbo's with 2 1/2 pipes. I can't wait til the weather breaks, so I can get the 300 to the muffler shop.

Make sure that those HPs don't have the usual cracks on ther backs by the collector.  If so, they can be repaired, contrary to popular beleif, but these manifolds are commonly cracked, especially the passenger side.

I stopped by the muffler shop today (without the 300) and the tech said I may have to start out with 2 1/4" pipes from the exhaust, then further back, change the pipes to 2 1/2". He said I might have a clearance issue with the 2 1/2" pipe near the engine and steering.
The HP manifolds point down with a rear facing angle compared to the stock ones. I know TNT fuseys had this set up, but I have never seen one close up. Anyone have pics of this area?

I was reading a post on the Dry Dock on HP exhaust manifolds. I read the left side (drivers side) HP's for the C body is specific to this body. Is the casting number 2806900 or 2883409 for a '69 440? If I have the HP from a B body, can it still be used or will either manifold work?

I don't think it will work due to the B-body manifold outlet being where the steering column will be...interference fit is a no-go.

Thanks Commando1! Once you gave me the right casting number, I checked eBay, and low and behold there it was, in the parts section when I did a search under "HP exhaust manifolds".
After the left manifold arrived from Oregon, I had both exhaust manifolds hot tanked, and then painted them. After the logs were replaced with the HP's, (didn't know the manifold studs went right into the water jackets...what a mess that made), I needed to decide if I should drive to the muffler shop, which is around 5 miles, with open exhaust, or have the 300 towed. Concerned of burning a valve, I called my AAA membership and had it towed for $0.00. Now the exhaust sounds great and the additional horse power is noticeable.
Right after I got the car back, I changed out the old Hercules 235/75R/15's for the BF Goodrich Radial T/A's 235/70R/15's. At the same time, replaced the dual point ignition with the Mopar high performance electronic ingnition kit from Summit.
The 300 now starts better, rides better, and sounds alot better!
