Newbie exhaust question
Newbie exhaust question
Can you guys please explain to me the diff between a muffler, exhaust, cat-back, and y-pipe?
I am just confused with all these terms. I know the muffler is just the chamber with the exhaust tip but what is everything else and what is the relative price and horsepower boost associated with em.
And what do you guys think of the powertech single tip, dual tip, and the DTM exhausts. Thanks

starting from the engine; the exhaust gases are collected from the cylinders and exit through what is known as the ypipe. It's called a y pipe because of its shape (it actually looks more like an f though) Replacing the y-pipe w/ an aftermarket one gives Maxs a great power benefit. The stock y pipe has pre-cats in it. A precat is used to reduce emissions while the engine is cold and the regular catalytic convertor hasn't warmed up to operating temperature. The aftermarket y pipes remove the exhaust obstructing, power robbing pre-cats. After the y pipe there is the catalytic convertor. This is required for emissions. After the cat convertor there is a b pipe (don't know why it's called b) the b pipe is just exhaust tubing to get the exhaust to the rear of the vehicle. The b pipe is right over your rear axle and also has what is know as a resonator on it. The purpose of the resonator is to silence and tune the exhuast sound. After the resonator there is the muffler.
For power mods the y pipe is by far the best bang for the buck. Reportedly gives 10-20 horsepower depending on other mods. The cat can be replaced w/ better flowing cats but they don't really give any noticable power benefit. Some people replace the b pipe w/ new ones that have nicer, smoother mandrel bends in the piping - this reduces exhaust obstruction. Some even remove the resonator and replace it with straight pipe. This will increase the volume of your exhaust, and to my knowledge will only give a little bit of power.
Finally, at the end is the muffler. THis is used to tune the exhaust sound. Mufflers are even now tunable with different end caps.
So, a cat-back system is when you replace all of the exhaust piping from the catalytic convertor back to and including the muffler.
DOn't know about the powertech single tip, dual tip, and the DTM exhausts. Hope this helps.

This might help you out. This how it is ordered starting from the front of the car
y-pipe --> cat convertor --> bpipe --> muffler
Catback refers to everything from the cat back. So if brand X offers a cat back system they are offering you the bpipe and muffler.

, Lets start at the Y pipe, it connects to the so called header aka exhaust manifold, --> Catalytic converter(emmissions) --> B-Pipe (long pipe extending to muffler) A resonator can be added here to reduce noise --> muffler (pick one!)

Yeah, my hands are still sore from all the typing. I just thought I'd try to answer any other questions that would pop up. I'm nursing a hangover right now so what else do I have to do?

muffler = Mufflers (the box and tip, gives car a little louder sound, cheapest way to go)
Catback = (new muffler, and pipes, some with new b pipes like greddy, gives car bigger pipes to let more exhaust out, alot better sound, a little better performance)
Ypipe = (connects to cat conv. lets more exhaust flow from engine. Makes engine a little louder)
If i were you id get catback exhaust (i like my greddy sp), y pipe (warpspeed- least amount of fitment issues and good product), and either popcharger or cold air intake
