no check engine light so far. the extension is pretty long, maybe about 30 in. long, but as long as its okay, its okay. now i have a clinking noise, i don't know what it can be, for example, when you put it in a higher gear and try to start off, it makes the engine vibrate a little more, so then theres a noise coming from the engine bay, i think its maybe the extension, i ziptied it along the tranny(it was the only way), the plug that connects the o2 to the other connector is maybe vibrating agains the transmission to make that clunking noise. it only happens when the car bogs and the engine is shaking alittle more than usual. has anybody else had this happen with header install? or could it be the header flange vibrating against the cat flange. its not that tight on there, and i can't get the spring bolts any tighter, so may be that too. lots of things, anybody care to share some insight? thanks alot

Hey people,
I was looking online and was wondering what the little mesh part on the pic below is. Is that some sort of catalytic converter or am I just dreaming? I've seen it on others too, like the HP Racing header. Please tell me it's a cat! =) Another question I have is I often see a bulg in many cat-back exhaust systems. What is that bulg? I have it on my greddy cat-back exhaus too. |

that's a (more) flexible section of pipe, to help the exhaust system survive all the flexing, shaking, expanding, and contracting that it will go through.
the bulge that you refer to is most likely a resonator, used to change the tone of the exhaust. Another possibility is that you're looking at the muffler...

yeah, the only purpose of a resonator (as compared to straight pipe) is to change the sound of the exhaust.

I read a few articles that said that if your car is not producing alot of horse power, removing the cat for a straight pipe will only give u an extra 1-1.5 horse's. It also explained that torque stayed the same or drop just a little. I think the best way is to buy a three way hi-flow cat. 1. smog legal 2. police 3, almost same amount of power. If i'm wrong please someone tell me.

Re: Catalytic Converter / Header????
With the money saved from buying aftermarket Cat's, it's worth getting a good local muffler shop todo some Art work welding.

Headers and supercharger
I own a 1981 gmc caballero base model. It is a v6 3.8 L. I am having trouble finding headers and a supercharger that will fit this. Does anyone know if they make these for this or if i have to put a different engine in it. If you can give me a websitei can go to or anything it would really help. Thanks.
