97'CL2.2

im in the process of putting togeather a custom 2.25" exhaust and was wondering what the difference between a "glasspack" and a resonator was. i did some searching but came up empty. here are two links to magnaflows website that ive come across. anyone with some input on the differences or which one is more effective at keeping things quiet would be greatly appreciated. also if you know any good places to pick one up at. thanks.

resonator by magnaflow: (they call it a muffler)

What motor u have? is the 4 cyl I havent heard a accord or cl 4 cyl that sounded good. v6 or go home lol

But on topic I would say resonator

97'CL2.2

<----------------97'CL2.2
ive heard a few which sound decent..i agree the v6 sounds better...but im asking ab glass packs not glass trannies

You could venture into the land of unequal length headers and make it sound like a subaru... Would be considered rice, but, if it were exciting to you, who cares.

Eric98Cl2.3

get a resonator. also consider a muffler with a baffle/silencer if you're worried about sound.
I had a 97 accord 2 door ex with a greddy full cat back and it sounded nice as ufck, it wasn't rice at all. Nice deep tone, 2.3 should sound exactly the same with a proper catback.

subie's sound AWESOME though, and most people would be like WTF, and not exactly realize what you have really done though

How would unequal length headers help him with performance though?

on1wheel01

Performance and 4 cyl should never be in the same sentence lolz. I'd be interested in how it would sound though. Could be promising

Says the guy who was making excuses to not run BlazinSi's H23a LOL. Don't get ignorant, theres plenty of performance 4 cyl's out there, and that's w/o any F/I. Ask Percy, one of your 3.0 brethren, he'd know. And I'm not being biased, I have both a 4 and 6 cyl.

I think Subaru is the only engines where it would sound right w/unequal length, the boxter engine makes it alot easier to give the correct exhaust pulses for the sound out of a 4 cyl that one would be seeking with that setup. With the stock f series, it might just sound like u have a lumpy cam or something.

97'CL2.2

tell that to john shep...he runs sevens in his 4 cyl...in fact i bet my 4cyl DSM would spank any v6 on this site...i went ahead and ordered the 22" resonator from magnaflow. with the magnaflow muffler i ordered and the full 2.25" system im thinking it will sound decent. we will see come spring or tax return

Eric98Cl2.3

Good luck man! I think you'll be fine.

actually there is a reasoning for those unequal length manifolds, it is in order to get the quickest route for the exhaust gases to the turbo, to get it spooled up faster, with where it is situated (instead of looping that right back around for equal length, instead just run it almost right back for the almost the shortest path possible)

cause on the N/A engines (not so much on the newer ones though ) the manifold runs straight back on both sides, and then they join up at about midway on the tranny (right behind the drain bolt actually), and then go over to the passenger side, then once it is fully past the tranny, it goes back to the center of the car

maybe not everyone (thinjim iirc comes to mind), but yes 99% of them on here

Tehvine

I definitely wouldn't suggest it for performance, but it sure as hell sounds neat on this civic.

So on an N/A engine would there be any advantages? I can't think of any being that theres no turbo to send those exhaust gasses to.

on1wheel01

Good points. Ill run him anytime, I know he'll beat me but im not worried. My car is a dd. My speed is in sig. Anybody can bring their whatevers here if they wanna race it(better run 6.0 or faster if u wanna beat it though).

there can actually be a performance reasoning for it on a N/A, especially if tuned properly for the air flow and fueling characteristics, of each cylinder (which at the OEM level would not be all that hard i would imagine)


and it would be to actually broaden the power band up, so it is over a wider range
basically what you are trying to do is make it so that NOT every cylinder (and the best bet would be to make companion cylinders the same length, such as 1-4, and 2-3 on a inline four cylinder) makes it's peak torque at the EXACT same rpms, but SLIGHTLY DIFFERENT rpms; you may not have any peak torques numbers to brag about though by doing it that way, but what you get is a more usable/streetable power band, that is broader, and more enjoyable to drive



and personally i actually prefer driving my TL over the wife's WRX, because it does have a broader power band, and also actually has some low end grunt, compared to having to wait for the turbo to spool up, to make it actually get going fast

new question similar topic...didnt wana make a new thread: is all T304 SS pipe created equal? i was pricing out some straight sections and bends and it came out super high. if pipe is just pipe could i get an ebay system hack it apart and weld my muffler and resonator to it and call it a day? or does pipe affect exhaust tone? i didnt think it did but im no expert, any one done this?

friesm2000

iTrader: (4)

there is a difference in pipe, and that would be especially in wall thickness, ebay=thinner, and YES it can affect the sound of the exhaust, by the resonate frequency of the pipe itself
ie: thinner wall=more tinney sounding; where thicker walled stuff=is more solid sounding/quieter


look at some of the german car's they are some of the quietest ones out there, and part of that is because the exhaust is heavy as shit, and part of that is the thicker wall piping used (on some of them , you can basically hit it with a hammer, and not even leave a ding in it, where the thinner stuff would be half crushed in)








as a side note: the thicker walled stuff will be easier to work with, especially with welding, that that is because it won't "burn through" as easily

jessb.s.o.h.c

True, the m series (bmw) has heavy heavy mufflers, that's why when you look at the aftermarket exhaust kits weight compared to the ones for Japanese vehicles its quite a bit different. But as for glass packs they are probably the worst mistake people make when it comes to the import scene..if you're going with sound greddy does miracles (i have a 97 2.2 as well) and I have a nice crisp deep sound, compared to the pooping sound sound I hear out here in nyc. But just a suggestion, if you're going to do your exhaust do it right and you'll be happy..

ok thanks for the quick replies. i got a local quote to do the custom piping for 150...i dunno if it was stainless or not...i forgot to ask...probably not.

friesm2000

iTrader: (4)

as said probably not, stainless is NOT cheap


for quick reference: $15 PER foot, and you are looking at at least a couple of feet, and that does not even include the needed bends

thats actually the exact company i was pricing pipe at...i live 5 mins from thier shop

i just had done a quick search for "stainless steel exhaust pipe" on lol

97'CL2.2

anyone know if 409 stainless is any better than aluminized tubing? its like half the price of 304 stainless because it doesnt have as much chromium and yada yada in there. anyone in the salt belt have 409 or aluminized pipe? im sure the aluminized pipe wont cut it but the curious as to how the 409 would hold up compared to the 304 and aluminized tubing

friesm2000

iTrader: (4)

iirc it surface rusts, but still not does not rust out like mild steel/aluminized steel; so not the prettiest out there if you want the entire exhaust to be shiny

DO NOT, even if there was a gun to your head, ever install a "glasspack" on your car unless your name is Bubba and have a V8. It's pointless rice for rednecks. They are very effective at reducing back pressure, but not very effective at muffling noise.

A resonator will help quiet the sound of your exhaust system. Its helpful if you want to have a nice free flowing exhaust system without sounding like a weedwhacker. I have one on my turbo CRX to keep the volume under control.

Yeah man. I've never seen a 12 to 13 second four cylinder daily driver before. Never..... (/sarcasm)

Hayduck

Are you talking 6's in the eight mile? Theres no way your car is running a 6 in the quarter.

I think he means the bike in his avatar.

well theres a definitive answer lol...thanx for the input...i got the 22" magnapack resonator waiting to go on

Calm down newb your new here and just joined the conversation. So if u can't read it all don't post. K? MMMM k.....

I wish my cl would run that fast. Jeez. Not that I dont like fast cars. Cacoa's car would be a dream for me. But I can't afford to do all that. So I just stick to a bike and lovin my free car as a dd.
