Question to all Dauntless V-6 Owners.

Hi I have a question for all you V-6 owners. Are you guys running stock exhaust(that is if its duel glasspacks running out before the rear fender????) Or what is the stock exhaust setup. Is there anywhere where I can buy a replacement quieter exhaust setup. Is the duel glasspack the stock exhaust? Thanks for any answers. I would prefer to be able to pick the parts out of a catalog rather than fabricate them.

 

Glasspacks?? Is that a fancy name for "mufflers"? If so, I run the dual setup.

While on the topic, I'd like to know if the heat riser is intended for the dual set up or for the crossover tube? Anyone know/speculate?

 

I think glasspacks are a funky term for the round large tube that I guess is a muffler. Not sure though. Im not sure if this setup was stock. Oh and one more did the stock setup have a crossover pipe to balance the pressure between the two pipes?

 

Yes I tried doing a search but couldnt really find exact answers to the questions I asked. I want to know is the stock exhaust the one I have, and if I can directly replace it with a kit from a certain manufacture?

 

The stock exhaust setup involves a crossover or y-pipe that runs just ahead of the transmission skid plate (if you have one). A single pipe then runs along the driver side, over the rear axle and then, depending on the model year, exits the left or right rear after the muffler. Correction; There may be one factory setup that had the muffler before the axle bend. Glass packs as you called them were not stock. There's a good diagram of the exhaust setup in the FSM (Factory Service Manual). Unfortunately, no one makes a stock replacement exhaust system for our V6 CJs, at least none that I've been able to locate. Please let us all know if you find one. I think most of the members here just take their rigs to a local muffler shop and have them install a custom system. Hope this helps.

 

I bought a stainless set - including the elusive Y pipe - from Kepich Muffler in FLA. I don't have a phone no. for you but they advertise in Hemmings Motor news. It's pricey but you will never have to rplace it again. AM

 

I think it would be hard to to compete with the price of a muffler shop, when you consider what they would charge for a complete exhaust system designed for V6 CJ's with shipping, etc. The stock tubing for dauntless v6 = 2.00 inches with a .065 inch wall thickness. Many on this board have got manifold-back systems installed for less than $200. Guess if you have a selection of shops and shop around it could be possible.

My system is as described by beeser. Y-pipe to skid plate, single pipe on driver side over the rear axle then muffler angled out towards passenger rear at ~45.

Alan, the heat riser should not depend on what comes after it. The coil (~thermostat) causes the valve to open when warm. I don't think it cares whether the exhaust goes out one pipe or two.

 

OK. I've had "Cherrybomb" mufflers, which fit that description. Those the same?

 

A cherry bomb is a type of glass pack. They were very popular in the late 70s and early 80s. they are still a good way to get a free flowing exhaust if that fits your application. Great for horsepower, not so good for torque to to lack of back pressure in some applications. They come in a wide array of lengths. They are torpedo shaped tubes .You simply weld the inlet pipe to one end and exit pipe to the other. If you look in a summit catalog you will find them. They are not a bad exhaust and very economical, they have a limited life span before the fiberglass inside deteorates completely and sound like garbage. If it helps, I didnt like the sound of them on my dauntless either.
