Default After Market Exhaust?

Hey guys I'm new to this site and planning to buy a trans am when I grad pretty soon here. When I do I want to get a new exhaust either the same day or pretty soon after. I'm going to get a 98-99 ls1. What I was hoping was that someone would have the following exhaust and be willing to post clips IN and out of the car with some revs. Borla, GMMG, Loudmouth, and corsa. I'm looking to have a daily driver and worry the loudmouth is going to kill my ears and prevent me from listening to the radio or talkin to someone comfortably. Thanks

Thanks thats exactly the kind of input I'm looking for. I personally do like the sound of the loudmouth but that was a concern I had; the interior drone or potential for that. I also was asking because I live in northern Virginia and wonder just how loud I can go without having a cop give me a hard time. The only reason I would not go with the loud mouth would be because of the cops.

Keeping with the same question...If I'm in an urban suburb area are the cops going to harrass me for having a louder exhaust even though it's emessions legal? If so whats the middle ground between stock and LM exhaust

You will attract more attention though, which can be a good thing and a bad thing <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Any of the exhaust you mentioned, GMMG, Corsa, Borla, aren't going to be quite as loud as the loudmouth, which basically has no muffler since the muffler is just an empty chamber. I would get a magnaflow exhaust if I were you. Those others cost too much, borla has too much rasp. I have a B&B that I got used. I would have never bought one new. I really like it. There's a GP on corsa exhaust right now too, check in the GP section, I know I saw it on ls1.com, might not be on here though. This is the first corsa GP I've seen, they wouldn't do em' for the longest time. Now, you say you are getting a trans am, if you get a WS6 with the free flowing exhaust that it has, you won't gain much, despite looks and sound and a lighter wallet, from an aftermarket cat back. You could just go with a cutout then and cap it if it annoys you. You can even go with an electric cutout and open it whenever you want from inside the car. Open it if you want attention and are going to race, close it when you want it quiet. Its just my opinion, but an electric cutout or a magnaflow exhaust would be great options.

It looks like I may have to go with something other than a loudmouth in Virginia. It would seem that it is illegal to run a chambered or resonated exhaust. If the system does not have a muffler with some baffle system then it is deemed illegal accoding to what I read. Anyone with any imputs about this would would be most appreciated I guess I'm looking at Borla, Corsa, or magna flow now?

As far as a good aftermarket system,, i have the Borla and love it. it doesn't rasp unless you get on it while parked and rev it hard. It's worth the 600 bucks trust me! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

SLP advertises them as 50 state emissions legal but makes no claim for the noise level. in the box that the loudmouth came with it had a piece of paper explaining that it is technically a muffler but resonatopr type not a baffle type and that you have to check local laws, not their responsibility, that type of stuff. if it says no resonator type exhaust where you live then i'd probably stay away from it, not really worth getting tickets. it sounds great, and unless you're hard on the throttle it doesn't draw that much attention. i've never had a cop look at me twice.

the interior drone isn't as bad as a lot of people make it out to be, just depends how sensitive you are to it. i've made long road trips in the car many times and it doesn't bother me.

i got it because it was cheap, sounds nice and all stainless steel. you could get the regular SLP exhaust which sounds nice and i think it's around $500 maybe a little more, can't remember off the top of my head.

Well thanks so far guys but... <img border="0" title="" alt="[Frown]" src="gr_sad.gif" /> I just talked to my buddy who happens to be a common wealth attorney for the state and... it's illegal as hell if it doesnt have a baffle atleast for this state. So I guess I'll be looking at borla, and corsa. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> Any other suggestions??? <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />

Good idea but not something I want to mess with. The biggest reason I'm doign this is to get a better more muscular sound out of a MUSCLE CAR. I'd be happy with the WS6 exhaust if that would do just as well. Whatever it is it has to have a muffler with some kind of baffle system... <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

How exactly do you think a cop will know what is inside your muffler? They don't have Sawzall's in their trunks you know. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" />

If you've got cats LM is not that loud. A cop will only notice it if you're driving in a manner that really makes the car noticeable, like WOT. Also, when it comes to noise level, cops don't usually just go around picking on cars that sound louder than stock. They have a lot of better things to do. BUT, if you start going WOT around your neighborhood and get your neighbors pissed, and they start calling the cops complaining about you, then you might have an issue. Or if you get pulled over for something like speeding and give the cop attitude, he'll start looking for other things to pick on. You'd be surprised at just how many things a cop will overlook if you treat them with respect and don't try to bullshit them. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Anyway, you are stressing out way too much about getting pulled over. I've known people with heads/cam LS1s with no cats and LM go for years without ever getting a ticket for loud exhaust.

Moral of the story, take it easy and buy the exhaust you like! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> That is unless of course, you have a local cop that hates your guts and is looking for reasons to hassle you <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" />

i think i'd worry less about how the muffler works and more about the overall noise. i think you can get a decent sounding cat back that won't be really loud. it seems to me that the reason that they have the law is to keep noise down. meaning that they probably have a certain dB level law and if they think your exhaust is too loud they're going to give you a ticket if it's resonator or baffle type.

there's no way for them to tell by looking at the outside of a muffler, other than a bullet type or resonator like the loudmouth, if its baffled or chambered. they're just gonna go by noise level.

Basically every town in this country has some sort of noise level restrictions. Question is, how strictly do they inforce them? In most areas, it will take complaining neighbors or other more serious offences (like racing or speeding, etc.) for the local law enforcement to even waste their time with it. Loud exhaust is not a moving violation, which means that for most towns the ticket they give out is an oridance violation, which brings in MUCH less money. They'd get twice the money for giving a speeding ticket, so why waste the time on loud exhaust if they can get a speeder?

Another factor is, how many other things about your car make it stand out to cops? Do you have tints? Racing stripes or graphics that are very apperent? Non-street legal tires full time? Huge cowl hood? You get the picture.

The only thing about my car that really stands out and could be considered "illegal" is my exhaust. Yes, it is pretty loud. But I have a front plate now, no tints, street legal tire, and the exhaust isn't THAT loud (not like open headers or anything). Otherwise, my car looks stock.

As long as you are running the loudmouth through stock cats, it will never interrupt a conversation on a cell or in the car. I've been in a C4 vette with 40 series flowmasters that by FAR had lots more resonance than my car.

Loudmouth also outflows and costs 1/2 as much as corsa and gmmg <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

If you want your car loud, and since youre conisdering exhaust, im gonna assume you do, you wont be dissapointed with loudmouth.

Also try a search for clips, there are plenty out there

I put the Corsa on last night. It's got a nice, muscular rumble at idle, and sounds great at WOT. My car's a convertible, and converstion and listening to the radio is no problem. A little pricey, but very high quality. It's a nice system. <img border="0" alt="[USA]" title="" src="graemlins/patriot.gif" />

I still say you should get an electric cut out. Its not that big of a deal, they cut a chunk out of your exhaust and weld in the cutout, then you install the electric cut out, it takes about 2 hours if you really take your time with it and it cost around $200 with the install.
You said you want your car to sound like a muscle car, but every exhaust sounds different and its hard to tell what you will like. I'm sure there's someone in your area that has the loudmouth so you can hear it for yourself. Check out www.easternfbody.com and look and see when the next meeting is, if you go there, you can check out all kinds of LS1's, or look for someone that lives near you. I wouldn't worry about the cops. I seriously doubt they will ticket you just for noise, but if you have a loud exhaust and you get on it, its like saying, "look at me, I'm speeding" even if you aren't... its happened to me when I squeeled my tires and accelerated to the speed limit and got a pointless "failure to obey a street sign" ticket.
