if you want your new muffler you buy to be even louder before installing on the car, fill it with gas and light it to burn out any packing inside.

But open header will definatly loose power due to back pressure needed in your engine. The lsj will probaly see power faster due to being able to move more air thru the motor

ok so what if i did open header but put a fart can on it?? would that be enough back pressure?? cuz i have found a couple "fart cans" that sound actually good and not ricey at all...

lmao that would be hilarious. the header coming down with a fart cat attached right to the end of it

just get a skunk2 exhaust syste and put a loud ass muffler on the end then u get performance and sound. i just put a muffler on mine because im 17 and didnt really want to spend a lot of money on a new exhaust system

oh and dont run an open header, the exhaust will dump right under the car and could possibly seep up into the car (not so much now because it is new and pretty air tight).

also, an open header has almost no back pressure and it could possibly fly your valves

My recommendation if you are sure that you do not want to use a CAT is to cut it off and weld in a piece of pipe, leave the stock resonator welded on, cut the stock muffler off, weld a extender pipe and a slip on muffler.. aka "fart can"..lol.. Probably would want to go with a name brand muffler like megan N1, a cheaper one is a RS type N1 "clone"... or if your not much worried about, looks then you could weld up a flowmaster, magnaflow, dynomax, cherrybomb, or and universal muffler..
either way.. all of these muffler run in the 50-100 dollar price range.. I say you could piece ya together a pretty good sounding exhaust that would be be plenty loud enough, but yet retain some backpressure so there would be performance loss and have everything welded up for around 200 bucks..

I had a friend that had a setup like that on a neon.. Header then straight pipe all the way back to a fart can... it really sounded like crap.. you could here him coming from over a mile away..lol.. needless to say he had a major power loss...

to the op, if ur interested i have an exhaust for sale, it will bolt right up! and its cheap! pm me if ur interested

jacobmprater

i meant stright pipes to a fart can. not just open the header up under the car.

i know but it would be funny if someone welded the muffler directly to the headers

teh_punk

n/a 4 bangers need some restriction, too free flowing will = power loss. you will get beat by an 89 civic hatch. keep the cat on or get a high-flow, nothing bigger than 2.5" pipes to the back and throw on a magnaflow muffler and a nice looking tip.

lol threadjack but

i have 2.2 (g5 ftw) and am going with zzp combo with the 2.5 dp. but im going catless. and i will have a gmpp catback. do you guys think this will be legit catless? will there be enough bp fron the step down to the 2 1/4 gmpp?

dont flame, if i seems like im an idiot or noob or whatever, im not. im just looking for opinions

Chuck

The gmpp catback Has a resonator and a good muffler so you should have good back pressure.. Your exhaust may pop and crackle when you let off from hard throttle, but all in all you should have a nice tone.. 2.5 pipes would give ya alittle more flow and a deeper tone..

im thinking 2.5 will be too big for my 2.2 with just in intake and the full exhaust of course. and i have a flowmaster muffler on there right now and it has a nice gurgle durring shifts and when you let off. i love it. some people like the smooth sound when you let off but i like the gurgle. im sure ill love the crackles.
im going touring btw because i heard a catless dp with the performance and its really loud. so the touring will take a notch off. it will still be loud but not as. and the touring is a bit deeper to start out with

Chuck

The touring GMPP with a Catless downpipe would probably be the best set up for a mildly modded engine.. Probably would not be to loud..

teh_punk

2.5 is perfect.. i used to run mine w/ cat and 2.5 pipes to a stainless tip, no res no muffler.. that was crazy... it would pop and crackle so loud it sounded like it was shooting flames.

Watched your launch videos.

Launch at 2200 and feather the clutch. You'll get off line quicker.

i have a full 2.5 exhaust from the collector to the muffler, got the vibrant header and dp with high flow cat and the megn exhaust, and the tone of my exhaust is nice, i am currently waiting n taking it back to dyno since i got the vibrant stuff to see if the high flow cat made a good diffrrence over stock or not

Fallout

Keep your cat on or you are gonna fry o2 sensors like crazy, probably run too rich (unless you get it tuned) and you'll just plain lose power. Instead get a high flow cat to at least retain some manner of cleanliness and backpressure and get a megan racing exhaust you will be more than loud enough. And if that isnt enough get a header DP and intake. It'll scream and actually make some power. Somewhere in the neighborhood of 15hp and 23ft/lb at the wheels.

your stoopid...since when does going catless fry o2 sensors...and if anything he would go leaner, not richer

IonNinja

i was at the track last night and there was so many Hondas with exhausts that were loud as all **** running 16's

what is the point if you're still gonna be slow?

05redline

Best response so far.

jacobmprater

would i have enough back pressure if i went straight pipes and a fart can??

Chuck

NO!!! you need some sort of restriction to have backpressure..A converter or resonator ,etc..

Having no converter will make a vehicle run leaner...but for the most part you will have a annoying CEL.. but there is really no major adverse effects to not having a converter.. Just noise, CEL, and may not pass emissions test...

notice how 90% of these posts come from people with supercharged vehicles.

ask any of my "car friends" and they will tell you that i feel the exact same way. i tell them that the more i mod my car, the faster gets and the louder it gets, but im still slow.

the thing that bothers me is that the people that feel that they are "superior" because they have the faster car models, or more mods, or whatever. if people go out and run 16+ second quarter miles, so what? they are out doing exactly what you are doing. racing. they are doing it because thats what they love to do. they are no different that you or anyone else on the track. someone with a slow ass 17+ sec car could have way more heart into the sport than someone with a 12 second car.

i know my car is slow, and i know it will always be slow. the thing that makes it all ok is that i have a lot of heart put into it. i can go out and run in the 15's and feel ok because i am doing what i love to do, drive my car.

you are entitled to think and say whatever you want, but come on. dont be one of the people that hate on people with slower cars than you just because. most everyone here is here because they love their cars. dont put them down for that just because it is slow. of course there are the select that are here to know how to make their car loud as ****, but for the most part people are legit. people ask dumb questions sometimes, but dont put them down because they have a 2.2 and you have the god almighty 2.0 sc.

come on. pick me apart for all i care, i mod my "slow" car for the same reasons anyone with a ss/sc, redline, srt-4, whatever mods theirs. i probably have more heart in my 2.2 than most have in their "fast cars"

im thinkin if i could use a glasspack as a resonator and a fart can as my muffler. would i have enough then???
