X2.

If you cheap out you will just be replacing it again and again and again. Spend the money for a quality Stainless Steel system and you wont have to worry about it rusting out or fitment issues.

Yeah there cheap for a reason...

As in the canister part of the fart can will fall off.. it will all rust.. the hangers wont like up and it will look like poo.. the flange will not bolt up right and will leak (and sound like poo).. the fibergalss packing will all fall out (and also sound like poo)..

I dont think im missing anything...


They suck.

Custom tubes ftw.

If you're not doing anything else besides muffler (hell, even if you're doing a full exhaust) go for a Dynomax Super Turbo muffler. Excellent sound on our cars.

i want a full exhaust including header and everything, of course without the cat and resonator
Re: cheap exhaust worth it?

If you ditch the cat and resonator you ditch the deep sound your looking for. plus you get what you pay for. I have about 650 into my exhaust and I attempted to go cheap while doing it right and piecing it together.

200 for the header
100 for the 3inch catback, just the pipe mandrel bent
200 for muffler, cat, and resonator
150 for custom down pipe, welding it all, and changing the on the header flange to use on my 2.3 head.

these are just estimates based on my memory.

Magnaflow has always been a VERY popular choice:

well, i honestly i think i could deal with a little worse sound for the little extra power.

I second that. Magnaflow is a very good brand! There is also Borla, but they are even more expensive than magnaflow.
2 weeks ago I put a Magnaflow 14821 Street Series Muffler on my '04 cavy and was surprised with how deep of a tone it gave my car. I've only done an intake but it sounds great.
The muffler was like $110 and then there was the install and tax so the total came to $155. I definitely recommend these mufflers. They're stainless steel so they look great, but more importantly they sound great.

here's what I got: Magnaflow 14821 (i bought mine through dealer, not amazon)









And now you are reading my signature...great

My ebay muffler was $30 and sounds exactly the same as my old street series magnaflow.

I totally agree with you but cats and resonators kill power. so i could deal with it not being deep by ditching the cats for the little extra power

high flow cats?

now theres an idea

very true. how much does a good one cost. I've been looking on summit racing and i found pacesetter to be pretty cheap. header pipe and muffler shipped is 452 bucks. would the pacesetter hold up?
Re: cheap exhaust worth it?

Pacesetter cat back will rust out, so will the non armor coated header from them.

a cat will not lose power...you just have to pick the right one for your car. you need your exhaust to be a least a little restrictive, otherwise you lose hp. i suggest learning a bit more about how an exhaust actually works(its not just a pipe for the gases to flow out of your car) before trying to get a setup. the header will probably be the most important thing, but everything is important.

but think about it, if all of this was too restrictive, then we would all just mod out drag cars to have an open exhaust. if what you're saying is true, we should all just unbolt the manifold from the head, and we gain a bunch of power. learn more about it...you don't have to spend a fortune to have a decent operating exhaust that is optimal for your car.

im not saying that. i know you need backpressure, having all the pipe all they way out the back and the muffler is enough. why do you think when you buy an exhaust for a car like a camaro, a corvette, a mustang, and so forth everyone gets "off road" pipes. because they dont have cats. but they still run it out the back to the muffler. because the muffler and the excess pipe gives it the back pressure it needs. i know how much power you lose with no exhaust. mine fell apart at the flex pipe and i had to take it off right there. and thats why im looking for a new exhaust.

Wow. So if you lose power with "no exhaust"? Then why do people gain better performance when they use a cut out?

The main reason exhausts run all the way out the back of the car is safety/legality issues. I know(in PA atleast) that you have to have the exhaust exit behind the passenger compartment. So the gases will not enter into the car and affect the driver.

Backpressure = Myth.

because putting a cut out does make it open exhaust, its just an open hole. some of the exhaust still goes through the rest of the exhaust. and it still gets the needed back pressure

Back Pressure is a MYTH!

Read the FAQispelling the backpressure myth.






Re: cheap exhaust worth it?

Just a small addition to the myth about backpressure. There is such a thing as over scavenging the exhaust, especially at low RPM. This is probably where the backpressure myth started. Ideally, a 4 cycle engine would completely pass all of the burnt gasses out of the cylinder without contaminating any of the intake charge or pulling any of the fresh charge with it during the valve overlap period. Unfortunately this doesn't happen in a 4 stroke engine. The best compromise is to have an exhaust system that keeps the velocity high and couple that with a camshaft with the minimal amount of overlap to fill the cylinders with fresh air/fuel and not dump it out the exhaust pipe.
