Yay! my first installment of low-buck mopar muscle is done. Went from old crusty stock exhaust to new crusty exhaust with some attitude
Replaced stock cats w/ 2 1/2" strait pipe (savings of about 20lbs right there atleast!), and a rear muffler delete w/ 2" crossover pipe. Sound? Like a pissedoff hornett with a chainsaw
Nah, it actualy sounds quite good, a crossover tubed (aka H pipe, or X pipe if you want to fab one up) helps ballence the load between the two banks much better.
-Cat delete sections are 2 2 1/2" pipe 22" long. Cost 10$
-Muffler delete consists of 2 2 1/2" pipe sections ~16" long (cut just in front of the stock muffler, and about an inch past the tip welds) and 1 section of 2" pipe. Total cost for this section 8$
Total cost: 20$
This is not counting the air tools I used in the R&R, or the welding equipment.
still have a small leak on the drivers side bank, where the first weld was cut. I'll fix this tomorrow, but overall very sound. Weighs ~30lbs less than stock i'd say, and still 70lb lighter than a SS system.
The only thing that ***** is that dodge's section of pipe that comes off the manifold and curves around to meet the cat (welded) is not a true 2 1/2 section, it's smaller somehow. a 2 1/2 flared end will make a larger gap than one would like, creating the point of leakage. The rest of the system goes together tight, and very solid metal-on-metal contact.
I tapered the end of the 2 1/2 flare to make the contact better on the inlet side of where the cat used to be. A good hit with the mig welder should make everything work out. Like I said above, I had a minute leak that i'll fix in the morning.
I would recomend a ballance tube to people, even w/ stock or replacment mufflers. Seems to help a bunch. Anyone tried a X-pipe yet?
So, for 20 bucks and some good old fashion bonding with my car, I've got a much louder system that should flow a bit better. If I ever decide to play nice by EPA standards, i'll throw a high-flow cat back on, but I doubt it
