Best Catback Exhaust Available
What do you guys think is the best catback exhaust available for Cobalts?
I've been really impressed with the Hahn 3" Catback, but wondered if anyone had one they thought was better.

This leads me to believe that the TC guys can get any aftermarket exhaust that is available for the SC.

Alright...well to settle this argument down...
What company do you think makes the best exhausts?
I haven't seen any that LOOK better than Hahn...anyone have an exhaust that you think is better?

If you havent seen or heard about any better than Hahns than why would you want a different one? Theirs is 3", stainless steel and sounds great. And it is relatively inexpensive.

It isn't like you can tell a difference until it is purchased and on the car. I'm trying to see if anyone really likes there exhaust and wants to let me know that I should consider it.

I personally LOVE my Megan Racing Drift Spec exhaust. It's not raspy at all and has a deep tone to it. I do believe the flange is differant for the SS/TC though. if you can get the flange made for it this would be my reccomendation...

On a side note, couldnt someone just get a custom exhaust made with whatever muffler they wanted? I know my local exhaust shop could do it for me for under $400, 3" from the catback with whatever muffler I want.

Becareful going 3" if you don't have the motor to back it up. I wouldn't recommend it unless you are over at the very least 275 whp and 300whp would be more desireable. 2.5" or 2.75" wouldbe sufficient for most stock or lightly modded balts out there. You'll **** up the pressure in your exhaust system if the pipe's too big for your motor...

like I said personally I love my Megan Racing exhaust and after hearing it on my car if I would ever (hypothetically) switch to an SS/TC I wouldtake the megan racing exhaust and have a custom flange made to match the one for the SS/TC and use it. It sounds amazing and I've even had Honduh guys comment on how good it sounds...
If I remember correctly their exhaust for the SS/SC is 3" too...

Can't believe everything you read on a vendor's website. Here this should shed some light on what I'm talking about. YOu need to find the exhaust that allows the maximum velocity for the exhaust exiting the tail pipe. Here are a few quotes that explain what I am talking about. I fond them in a thread a few weeks ago and I really think they explain the subject very well...
Its not backpressure that improves the low end. Pressure in the exhaust of any kind is bad.
Its proper exhaust sizing that allows maximum exhaust gas velocity at the lowest amount of pressure to aid in exhaust gas scavenging.
Too large of a pipe will not allow maximum exhaust velocity. Too small and it creates backpressure.

getting there!~
in simple terms, let me tell you what backpressure is. your engine blows out air. the air needs to get out of the exhaust. having the proper size exhaust give you the proper EXHAST VELOCITY. the idea is to get the air out the end of the exhaust as quickly as possible. if the exhaust is too big, the air kinda "dribbles out" the end. if the exhaust is too small, the engine has to work harder to "force" the air out. having just the right size piping however gets the air out fast enough, lets the engine run more efficiently, and doesn't create any drag.
now, backpressure and why it's bad. backpressure is jsut what it sounds like. air moving the WRONG way through the exhaust, back towards the engine. when you have backpressure, your engine now has to work harder, because the air it is trying to force out is being pushed back towards it.
i like to use a straw and spitball analogy, because it's easy to understand. take a spitball, (represents the air coming out of the engine) put it in a straw, (represents your exhaust) and blow. if the spitball is the right size for the straw, it shoots out across the room with very little effort. take that same spitball, and take a paper towel roll, (exhaust that's too big) and try to spit it across the room. doesn't work. it just flops out the end. doesn't seem like anything, but if you were spitting thousands of spitballs, they would be hitting each other holding up the flow.
so now, let's say you are trying to spit the spitball, and someone else goes on the other end of the straw and starts blowing back at you. that's backpressure. you're trying to shoot the spitball, and someone else is blowing it back at you.
that being said, in no way, shape, or form is backpressure good, regardless of engine, car, type of induction, etc.
i hope this makes more sense and helps you realize why backpressure is no good, and also why the size of the pipe is also very important.

you're basing the best exhaust off of looks?
seriously?
megan racing sounds like hammered ass on a ss/sc car. really. anything does.
some of you are forgetting something important here.
STOCK DOWN PIPE.
