Headers and Exhaust - TOO Loud!
Monday, September 11, 2006 5:12 AM
So yea, I need a bit of advice and hopefully I get back a substantial about of reply with the same area of tips and advice on this matter.

I took my car to the shop to have Headers (OBX) installed and a custom piping all the way to my dual exhaust on my 2000 2.2L. The only problem is that its too damn loud. Another thing is that the tone of the sound is great but the sound is amplified way to loud and i'm afraid of getting a ticket especially living here in miami. I have a resenator but not a caty on the piping.

Ok so here is my exact set up having to do with exhaust and maybe i can get some help from you guys.

Short Ram Air Intake.
OBX 4-1 Headers.
Custom Crush Piping w/ Resenator.
Dual Exhaust.

Any advice in keeping the sound and making it sound less amplified?

Thanks!

How long of a resonator? a 24-36" glasspack will deaden the sound alot and won't change the tone much.

I'm pretty sure it was a 12" or 24" because i for sure didnt see a 36 inch resonator on my car lol.
Any other ideas. I've never seen or heard of such a long resonator.

I have a Magnaflow Hi-Flow cat and a 32" glasspack with a Magnaflow muffler, real quiet until I step on it. Never gotten a 2nd look from the police about it.

Oh, I read it wrong. I was thinking you meant a 24" to 36" resonator and you meant 24" to 36" glass pack.

You shouldn't have gotten crush bent piping. I would have at least opted for compression bent.

So then would I have to get a Magnaflow Hi Flow Cat or a 32" glass pack to make a difference, or both. Since I already have a resonator, can I add any one of those?

I know now that i think of that. But many ppl that I know have had crush bent and it sounds great but i didnt know it would make my cars exhaust amplitude so loud. I think the sound became much louder of course because of the headers.

Crush bent?! you should have stayed stock then, the performance isnt even worth it unless its Compression or Mandel Bent.

put a cat in, that will quiet it down


or another resonator

Which one will give it less restriction then?
If I put a Cat or if I put another Resonator?

you wont notice any restriction really unless your running 15+psi lol

So if you had the option of choosing one, which would it be for you guys?

A Cat or a resonator? and why if you dont mind answering.

I appreciate the feedback.

I meant a Cat or ANOTHER resonator because I already have one on.

does it really matter what ones more of a restriction? you opted to buy the worse type of bent tubing for your exhaust (crush) so i doubt that the cat, or resonator is going to be the point of your restrictions, and obviously you don't care that much .

Get the cat first. At least if it's still loud and you get pulled over you won't get a ticket for no cat. Sorry I didn't read that you didn't have a cat. That helps alot. You can read around there aren't really any benifets of taking out a high flow catalytic converter.

What do you mean by there arent really benefits of taking out a high flow cat?

You only really gain like 1 or 2 HP off the top of the PEAK of the engine's powerband. The only time you want to take it out is when you are scrounging for every last HP and by that time you've already run underdrive pullies and stuff already...espeically on a road vehichle...plus, driving behind someone with a removed cat or bad cat sucks because their car stinks like crap.

And if i do install a high flow cat does it matter which order the cat and the resonator are in meaning who goes in goes first from headers back?

You want the cat as close to the exhaust ports as possible so it heats up fast and enough. You have the cat too far from the engine and it'll never heat up enough to catalyze and will be worthless in the system. If you have a header have the cat bolt onto the collector then the rest of the system after that.

Yeah gotta get that cat put back on. A ceramic core will flow way better than stock, a metal core will flow a bit better than that, and honestly, a test pipe will only yield slightly more power than the metal core. And metal core cats are quite a bit more expensive for the minimal gains you get compared to ceramic. Run the longest possible glasspack muffler you can find that will fit - like a Thrush or Purple Horny or something like that - this is what they're referring to when they say resonator. If you get one that's long enough then you can run it right off the cat and you'll only need a short section of pipe bent to go from that to the muffler. You won't lose any power by running the glasspack snce it's straight through but it'll really quiet things down.

Header -->cat-->resonator-->rear section-->muffler.

What kind of muffler are you running or if your running one at all? The type of muffler your running could make a big difference of the what sound and how loud of a sound it makes.

I also agree that you should of went with mandrel bent piping. Get a highflow cat to help deadin the sound as stated by other post

To tell you the truth i forgot the mufflers i'm using on the car but thats not the prob because the sound is awesome, and i have been using those mufflers for about two years and it gives me a deep throaty sound which is hard to get on a 4 banger. The only prob i was having was with the volume of the sound coming out of the exhaust.

But i think i'm gonna go with what everyone is mostly saying which is the Hi Flow Cat.

I say get a Magnaflow Hi-Flow cat

I actually wanna hear what it sounds like, got any sound clips?
