I have a 2k cavy 2.2 engine w/ cold air intake and catback dual 2.5 in exhaust. I am currently turning my car back to stock. The head is P&P"ed w/ stainless valves from Si and a 3 angled valve job. I know w/ that u need more in and outflow. So I was wondering if I could go to a single muffler exhaust and if that is a problem then could I just put a header, high flow cat and then the single muffler?? I just don't want the loud mufflers anymore. It isn't really that bad at all now but if I could get rid of one of those mufflers then it would be a lil quieter. I am out of the hobby now and wanna drive my car yr. round. B4 it was in a garage in the winter. Its a 2k and only has 40k miles on it. If anyone could help that would be great. I just want it to run right and not have problems or lose hp. Thanks

you can switch your exhaust to just 1 catback. your cat back starts after your high flow cat, so having a single 2.5 shouldn't hurt you much, as for the loud sound try having a resonator installed. with those you shouldn't lose any power, if any it shouldn't be much.
Truthfully you can't run your car stock and keep the power you have now. with what you have it isn't much but still to run stock you're gonna lose power. not trying to hate of anything.

if you dont want as much noise, cut down on pipe size as well as add resonators. which will increase exhaust velocity as well as absorb more noise.
guys with the gm supercharger are running 2.5 inch pipes. theres no way a 2.2 unless running forced induction or nitrous needs that large a pipe.
if you wanna stick with it, cool, but add some resonators cause sound bounces around inside pipes, especially when exhaust velocity slows down.
I have a catback exhaust. The resonator is still there. So I guess its a resonator-back exhaust!! LOL I know a lot about my car but if I go smaller it is going to restrict outflow, which in return will hurt the hp and maybe even the overall perf. of the car. I am keeping my cold air intake and I might just upgrade to a header -2.5in after header to the high flow cat- then 2.5 inch back to the single muffler. I guess I'll deal w/ the noise b/c I wanna keep the power. I know its a 2.2 but it is very zippy. I whooped up on my friends ecotec he had catback exhaust and CAI. I still pick on him about it. Thanks

dont know much about exhaust velocity and stuff do ya?
its not the size of the penis! i mean.. pipe! its the motion in the ocean!
its not the size of the ship, its the motion in the ocean, but it takes a long time to get to england in a row boat....
but on the subject of pipes, larger can give you higher hp numbers, but then again larger usually takes away low end puch or torque down low. so in a race of two similarly equipped cars, the car that makes more hp, isnt really all that effective in a race when the other guy already has a jump on you downlow and you try to pull out the win at the end...
hence the story of the tortise and the hare. or a bullet as an example.
shoot a bullet out of a cannon, you;ll get alot of visual, noise, and sound, and power (can stuff more powder in a cannon), but the bullet wont go far...
you get a pipe more suitable for the output, like a gun made for the bullet, the bullet travels fast and is more efficient
to large a pipe things exhaust flow slows down on low end, at WOT it speeds up a bit. so your low end is damaged.

now this is something i've heard a bunch of times before. a dual exhaust is louder? to me it doesnt make sense...if you have an extra muffler, usually it will quiet it down more than just having a single. i've seen and heard duals on a car with the same setup i have for a single and it is a bit quieter (same engine). maybe i'm missing something here. i just dont get why people want to
get rid of a muffler to make it quieter. ditch the stock resonator and add a better, straight through aftermarket one....or even two. that'll quiet down that drone you dont like and you still have the dual outlets you like (if you like duals)

I wouldn't imagine being that you have one more muffler it being any louder. It has more to do with the piping size and if there are resonators like Event said.
By the way, Event, you are the man...peace

That is why I don't post on here anymore. I was asking some simple ?'s and got some stupid a$$ poems!! Just forget about it. I just don't understand (EVENT) why you couldn't just answer my questions. Yes I do know alot about cars but also there are things I don't know. Which that is why I enjoyed the hobby, to learn more about shi* like this. If you can't give a straight answer w/o being a immature BITC& then don't give one at all. My friend had dual and put a turbo on his cavy, he went to single 3 inch exhaust and it was quiter than his dual!! Y??? I HAVE NO FUC*ING CLUE!!!! I talked to my exhaust man last night about it and he said some of the things event said and he told me if you wanna cut a muffler out then buy a header, high flow cat and 2.5 inch the whole way from the header back and that will work better than what I have now. WELL THANKS FOR NOTHING GUYS... NO MORE POSTING ON HERE!!!!
i don't see how event didn't answer your questions. he only told you what works best and how to go about doing it.
I was a retard, and now I'm permanently banned.
He did answer ?'s but whats up w/ the freaken poems!!! He couldn't just answer my ? he had to type all that other @!#$. I am just fed up w/ people on here. Some people are great and others are just annoying but whatever. I am out of the hobby now so no more worries.

He did answer the question. And as anyone knows around here Event > All
I don't care if he's the president, its the way he answered them all cocky and @!#$!!! No need for it!! I think my left nut knows more than he does!!!!
I am deleting my acct today when I get home so I don't care anymore. Have fun everyone!! I am out. Next project will be an old american muscle car. Of course that will have to wait til after we get a house next fall.

that obviously was to him....NOT YOU... but since you have to be mr i got sand in my puss....
i started back on the subject of pipes and answered your question along with adding in examples....
they were examples that hopefully anyone who can sucessfully wipe their backside can figure out with using a visual.
you said you dont want the loud mufflers, i told you to drop the pipe size. tried to give you examples of how noise is amplified through oversized pipe and how exhaust flow stagnates, which decreases over all performance....
if you dont wanna post anymore, then dont. but atleast stop acting like a spoiled female dog, and going off WITHOUT using that lump 3 feet above your arse, thats supposed to hold your brain.
also you wanna talk about immature, re-read the post i just quoted from you. if you dont understand the real world examples i put up....say so.
however you chose to go off on me.... take your own advice and stop being an immature b^tch as you put it..
read this
http://magnaflow.com/05news/magazine/05sportc.asp
it pretty much explains exhaust flow.
but since you are out of the hobby over something petty, its good to know when you get into muscle cars, if someone doesnt cater to your every needs, and pat you on your arse and tell you "you done good" you;ll throw another temper tantrum online again.
we dont need to know your next project, we dont need to know you are quiting, drop being an ATTENTION WHORE... move the F--- on!
so in summary:
-quit being a female dog, grow some nuts cause frankly your actin like a mama's boy,
-learn to read and think about things, before you reply.
-quit lying. you claim you need info in your first post, but then claim your EXHAUST GUY said this and that. if he is so prestigious, then you really wouldnt need an answer from anyone else.
-and theres no such thing as acting cocky, etc through words on a computer screen. unless denoted, you cant read demeanors or mannerisms throuhg a screen. so refrain from being a drama queen, whos sooooo offended.
-and lastly dont even try to challenge anyones knowledge if you dont know how to quiet down your car. apparently both your nuts couldnt figure out common sense hence your need to ask, but i guess if you think with your nuts that would kinda make you a "penis head"?????
hahaha. PWNED!
you know i never thought bringing a little life to a f------ thread that probably has been answered about 900 times since i have been on the .org could be SO BAD... event answered your question the first time and you then basically said no thats not right. I hope you arent like this in the hospital when the doctors give you advice on what todo. lol.
I love how Event to insult you in an intelligent manner LOL
