@sharpshot i have a c4 vette with no mufflers with only a resonator it sounds way better than some flowmasters which were on my car when i got it so i removed them because it sounded like a truck and that what i call sounding like shit this sounds good till it shifts
@10072018 I have a WS6, my buddy has a Z28. I paid a couple hundred for a loundmouth 2, he just ran straight pipes with stock mani's and cats. I like his better!
It's not as loud as I thought it would be. I love all the exhaust engineers you have commenting about your video......Folks it's ok the mufflers unbolt right next to the transaxle at the rear of the car......It almost seems as if GM made it easy for us corvette owners to unbolt the mufflers.
At the risk of getting chewed apart on here I have to ask why anyone would want to run any street car especially a c5 Vette without mufflers? Seems pretty juvenile to me. Also despite of the comments about EFI not needing back pressure. That may be true, and it will do it's best to adjust. With that being said these cars are never meant to run without proper exhaust . Mechanically it may not hurt, but electronically you are setting youself up for a world of hurt. GM would laugh at this.
@bjsage "electronically" it won't do a damn thing to harm it, all the O2 sensors through out the exhaust, the only ones that matter are before the cat, after the cat the only purpose of the O2 sensor is to tell the computer that the cat is working properly, if you take your cat off, it throws a code that says "catalyst failure" which does nothing to the engine parameters. Even so all it will do is trigger a "service engine soon" light which again harms nothing. O2 simulator defeats that SES.
@GMisurdaddy Whatever you can think what you want. but maybe the reason the computer tells you things like "service engine" or what you said "catalyst failure" is because you shouldnt be doing what your doing? You can agree with me or not, but I still stand by my opinion that anyone who buys a 60k + car and drives around with no mufflers is quite simply immature. I for one would not fuck around with a computer in a car worth that kind of money regardless if you think it doesnt matter or not.
@bjsage LOL nah, that's why I bought an O2 simulator for my bonneville when I took the cat off, you can search any forums about any modifications, I would research before assuming anything, it does nothing to harm them I assure you lol
@GMisurdaddy like I said agree with me or not. I dont care what you did to your Bonneville. Simply put I think it's stupid, and you dont. I wouldnt take any risk on a vehicle worth that much money, and maybe you would. Who really cares. You telling me over the internet that Iam wrong isnt going to make my opinion change about how dumb it is. If you dont then thats your business. Im not the only one to think so by the way.
@bjsage Exactly, it's what YOU think, "opinion" and "fact" are two different things. If it harmed anything I think we gearheads would have found out by now, seeing that the LS1 has been out for 14 years now, and electronic controls have been around for much longer than that. If I were you I would learn about engines,controls and engine management before "assuming" things that just aren't true.
@GMisurdaddy ok whatever. Im not arguing with anybody over the internet. It is what I think so dont let it bother you so much. If you think Im an idiot than so what. Im not going down this road with you. If you cant handle my opinion than to bad. Just because something hasnt happened to your knowledge or what you have read on the internet does not make it fact. Because you say it hasnt happened doesnt mean it wont. You dont agree, so dont msg me again because Im not going in circles with you.
@shelbysc450 Incorrect sir, you do not need back-pressure on EFI. Back-pressure was needed for a carburetor to avoid burning exhaust valves, but it is not needed or wanted (for power) on EFI due to the computer can easily and quickly modify the fuel load in conjunction with the o2 sensors. More back-pressure on EFI = more fuel needed to run at the desired 14.7:1 air-to-fuel ratio and consequently less power. Less back-pressure means less fuel load needed to run at 14.7:1 ratio and more power.
Thank you so much for posting this video! I been looking for a sample of a C5 Vette with the mufflers removed, and replaced with pipes, but keeping the cats in. I did it to a few Mustangs in the past. Great sound, better performance - all for cheap. The exhaust smell gets really annoying and sickening, when the cats are removed.
@teppili & @suicidesucks08 Um...and WTF do you drive? Probably a fucking 3 cylinder Geo Metro with a wing and a fart can and some faggish AutoZone graphics on the side. Fucking ricer. I bet this thing could launch in 5th gear and blow the doors off your beater.
@kooobideh It jus might have been. A lot of car makers tune the exhaust to help pull gases from the front. When i replaced one of my fallen off mufflers it seemed faster! lol
This comment has received too many negative votesshow
wow so whats so cool about it??? just do a straight pipe same shyt onli muffling a lil the sound, plus it sounds tribble with out the exhaust anywayz... lol damn american car lovers. IMPORTS ALL THE WAY!!!!!
its ok you can't even spell terrible so we won't even consider you competent enough to comment on our cars. We have nothing wrong with imports its the fact that you guys think putting 4 inch mufflers on a 1.5 inch downpipe is cool when it sounds like my grandma farting. And you guys think you sound cool.
@chineesmunk... when you have to buy a honda do they give you free rice to make you feel better... they should give you a special pot so you can cook it on your boomtube... I bet that would just taste amazing!
damn straight my other car has a nasty oil leak and is garaged at the moment and I am fixing to take my vette just like this (but zo6) on a 5/6 hour trip. not looking forward to this at all.
i got an 04 vette and i was thinking about taking the mufflers off but wasnt sure what kind of damage i would be doing to the motor or the under carriage. Can anyone give me advice on whether i should or not
It's exactly like kud4u said; reduced back pressure can cause suction that holds open the exhaust valves, screwing up the timing, valves, pistons, etc. My advice would be getting a pair of electric cutouts, because they're easy to install and you can turn them on and off, so if you want open headers you can but if you want the mufflers on you can do that too, and be able to switch in between.
IDK if you hooked up turn downs but i did this for a weekend show, well i decided to hit the track day. I melted the rear fiber glass rear spring.... Yeah... haha so be careful atleast run turn downs.
I just did this to my 02 yesterday, but when i was try to take the right bank off, I couldn't fit the flange past the oil pass. So i cut the pipe at a 45 degree angle, then i did the same thing to the left side and just flipped the flanges over and pointed them at the ground to make a redneck turn down lol.
would it still melt them if your just driving under normal conditions? and just to make sure you just disconnected them at the flanges and ran them open from there?
back pressure myth lives!!! LOL As long as you are not running heads only with no exhaust manifolds/headers you're fine... heheh. If you do burn a valve you're running way to lean and need a tune :P
Well come down to texas and tell that to us flat trackers...If your running the cats you will be fine....Maybe I should throw that in so I dont sound like a fool......
If your running a high compression motor under load without back pressure (mufflers) or at least restrictive headers. the suction can create positive force holding open your exhaust valves longer than they are designed to and can cause valve/Piston damage....SOMETIMES....I have experienced this running flat track outlaw a few times .I solved the prob by using a pair of cats off a 95 crown vic hallowed them out and made a very simple baffle with 2 1/2 inch tube... (poor mans)
I love the car, but you need to throw on some borlas or something. I sounds a bit like a redneck truck when idle. Beautiful car though:)
