If someone can show me a build code I'll believe it. Its a popular mod though. The reason is that back in the day converters held so much heat and exhausts were not built with stainless pipe. The long tailpipes on those old rams rusted quick especially when driving in town. It was a combination of corrosive bi- products from the converter and lack of heat.
Nobody made cat back dual tip exhausts back then either, and a Warlock would have had to have a converter.
JC Whitney used to sell a kit that bolted to the stock manifolds and looked pretty factory. It came with chrome tips and jutted out at a 90 degree angle from the frame. The Red Warlocks' exhaust looks just like it. I've done the same mod to the two Pre 80's Dodge PU's I've had, and also to my 78 Ramcharger. The converter...oops...it fell off. . Nowdays...no exhaust shop would touch those trucks without reinstalling new cats.
NOTE: I believe the Lil' Red express trucks skirted the conveter issue by having a 3/4 ton GVW. Anything below that GVW had to have converters, and Mopar, who was skirting bankrupcy back then, wasn't spending money to come up with too many exceptions.

 

My 3 year old daughter just moved out of her room into what was a guest room so that her old room can be made ready for her new sister due in about 6 weeks. So all the stuff from that guest room had to go. I was taking it down to my brother-in-laws house since he needed that stuff more then we did.[/QUOTE]

Good lucky with the new kid!!!

 

These vintage trucks are becoming more rare. It's great to see one that has been fully restored.

 

The old cats from the 70's were horrible beasts. They were huge and heavy and cost a pretty penny. Now they are so much lighter and efficient. Exhaust systems use to rot out a lot faster on 70's vehicles than they do now. We had a 75 Catalina and we had to replace the exhaust like 3 times.

 

Definitely a cool truck. It does look a lot like a LRE. I believe the LRE's were only produced in 78 and 79. They were the fastest American production vehicle for those two years, which is awesome but isn't really saying a whole lot with the huge emission and gas crisis that was going on.
