why would someone want to change out their exhaust system? how is it an upgrade? is it just to make it sound different?

exhaust is your engine exhaling and the intake is your engine inhaling. Think about it, if you were running down the track trying to breath threw a straw you would be pretty tired and not able to go real fast. So upgrade get a bigger straw with less stuff in it so the air flows better. You would be able to breath easier hence go faster and farther. Same thing with intake and exhaust mods just letting the engine breath better so it can create more power.

I, too, agree with sal. I did install an aFe CAI, for better performance, and was thinking about a cat back system to finish the project. But for some reason, the aFe changed the tone of my exhaust. It is somewhat louder inside @ cruise, but when I "get" on it, it sounds exactly like cars from my past: 1968 Barracuda Formula S, 1972 Duster 340. At idle, it sounds like a boat (Malibu, CorrectCraft, etc). So, I nixed the idea of adding an exhaust, although it would would help with the breathing. I welded on a dual, intercooled Borla SS tip instead. :eek:rangehat:

sounds better.
more power (breathes easier)
better gas mileage.
sounds better.
sounds better.
and uh....sounds better.
So, am I to understand you think it sounds better?

Sal I think that was an excellent analogy......

Does it make it sound better? lol j/k. Although I've heard it doesn't do much for a 3.7 as far as sound. :(

so is this an intake mod then? if one replaces an exhaust, say with a flowmaster, since i know that name, does that change the intake as well or do you need to do another part? i read a thread where the guy just took off some part of the intake and then put on a k&m intake box.

i'm getting a trailer that will be ~5500lbs and plan on pulling it quite a bit so i want to make it as easy on my rig as possible. right now i have a complete stock jeep (hemi with the factory tow)

Two seperate mods. With the HEMI depending on what exhaust you get it doesn't sound so good when MDS kicks in shutting down 4 cylinders. Sounds like a annoying 4 cylinder/low flying helicopter.

an intake is totally seperate than exhaust. a new exhaust allows airflow to leave the engine quicker and easier which helps the engine breathe better and get more power. where as the intake sucks in more air so the engine can run. with a cold air intake, it sucks in cooler air instead of the air the engine puts off which is hot. cool air will help your engine put out more power (nothing extremely different, but noticable)
