Installing H Pipe

I understand the paint thing was an old racers trick, that was debunked, in a search for torque. An 18 inch collector is best, well beyound the collector thats stock on headers. Theres also a weird looking collector that apears to squeeze in the middle. I forget who does it. But it is nearly allways a power maker.

In how to hot rod your small block MoPar, "12 - 18 inchs behind the beginning of the headers collector." It also goes on to say the best location (this may seem to skip the inch , measurement) is "rearward of the transmission mount but not farther back than the U-joint. Compare this to the 12 - 18 in. diamension listed earlier on your specific headers for the best overall location."

I also used a Summit racing H pipe. It will come with 2 pipes to conect the left and right exhaust pipes. Ones is straight and the other is in a slight V shape. These will go into the other pipes in the kit which get spliced into the main pipe.
Welding is the way to go.
