So I'm going back to work this summer and I will no longer be a poor and unemployed college student. If I have enough money left before school starts back I want to get an exhaust installed and possibly get an intake. My plans for the exhaust job are as follows...

Cut out the stock exhaust behind the cats right before the Y goes into a single pipe and run a true dual setup from there. I'm pretty sure I'm gonna go with two Magnaflow mufflers with turndowns. I want a X or an H pipe installed also.

Any comments or suggestions about this setup would be appreciated. Nothing is set in stone, this is just what I have in my head.

 

just do straits after the cats its loud but sounds baddddd! Make your own air intake for $40 like I did. will get pics up asap

 

Thanks for the comment, but I want to stay away from straits. I've heard that they can do damage and I don't want it THAT loud.

 

What are we talking straight pipes with no muffler or straight with 2 mufflers? What kind of damage have you heard coming from running straights?

 

Personally, I like the H-pipe. I like the Magnaflow Idea, but I would look into tailpipes. The resonance inside the truck with turndowns will get annoying after awhile to you and your neighbors. Especially at night.

But honestly, you end up with an unbalanced system, because the left side is going to be longer than the right side because of having to run both pipes down the passenger side. Not a big deal, but that's why I prefer a good cat-back system on a truck. Better torque and good sound.

Unfortunately, they do not have the proper kit for our 08 yet. I called them again today to try to get a time frame on the kit and they say it is still in development. The 06/07 kit does not fit due to Dodge using a different cat converter supplier thus the y-pipe is different. I told them I have been waiting about a year and to get this done!!!!
Maybe by then, the kit will be available. It will be cheaper (and all stainless steel) and give about the same gain in power. If you open the system too much, you will lose some torque which is what moves these big ole trucks.

I would go with the Airaid Jr CAI. It removes the Hemi Hat and reuses the stock airbox with a high flow filter. Just as good, if not better than the much more expensive open filter designs.

 

I don't think the sound would bother me very much. I don't have any neighbors where I live either. lol. I used to have a 318 with a Flowmaster 40 series cat-back with turndowns and it never seemed loud enough to me. It may have been the truck having 250,000 miles on it though. As far as losing torque I thought if I left the cats and installed an H-pipe it would keep enough backpressure to support this setup. Am I wrong about this? I hadn't thought about one side being longer being a problem. Do you think it would be possible to have one muffler moved back a little to balance it out? That may be a stupid question, but oh well...

 

I'm talking about a true dual setup with two mufflers. I heard that just running strait pipes alone can do damage to the engine. Something about burning up valves or rings I'm not sure. I don't know very much about motors.

 

Why not get an electric cutout and that way you can control how loud or not loud it is?

 

Can't go wrong with a cutout, it is nice being able to control the tone of your exhaust with a flip of a switch.

 

I would suggest the cutout as well.
