I took it off and it is loud, very loud. Its a 2004 chevy silverado v8 and seems to be running good, but im concerned with it in the long haul? Am I do major damage to the truck.am I an idiot lol? Please Help!! Thanks
there are evap,hoses in the engine bay of cars close by throtle body generally they deteriorate from heat,you can replace these hose relatively cheaply,carefull though as some can be hard to reach,and connecters can sometimes fracture,hope this helps
I don't know what kind of mechanic you're going to, but anyone with a $20 code reader can tell you the code and reset it. If it's an EVAP code, the leak can be from anywhere in the system. The cap is just the most common cause.
Did you take it off completely and not replace it at all? You cannot run exhaust right out of the manifolds or headers legally. Also, backpressure is a concern, but only to a degree. You need to remember that your truck is controlled by a computer, and that it adjusts things accordingly such as gas, air, etc. You should have something on there, if for anything, to get legal again, to create that needed back-pressure, and to tune the sound of the exhaust. The loud part isn't what makes a car/truck sound good, it's the tone of it and how well it's tuned that makes a great exhaust note. If you plan any more upgrades, look into getting a controller or a chip for your computer.
The truck itself will probably be fine if the manifolds are still on there. Burnt valves from an exhaust that was not restrictive enough was a problem in the 1950s with the metalurgy they had back then, but it's not really an issue with modern designs. And the engine doesn't need backpressure to perform well. The trouble is, this could do a bit of damage to you if you attempt to run the truck with no exhaust system. If you remove everything, including the catalytic converter, you will have an engine that puts out more pollution - and sends it right into your cab. Not good. Plus, you're likely breaking at least two laws, running with no cat and having an engine that's too loud. At the very least, put on the emissions control stuff and add enough piping that the exhaust will exit *behind* the cab.
First, it's illegal to remove your exhaust. Second, it's sounds like sh-t with no exhaust. And if you removed enough of it, you probably removed the oxygen sensor and this will effect engine operation. The best thing to do is to buy an aftermarket exhaust system, commonly called a cat back , meaning you get new components from the catalytic converter to the back of the vehicle. Systems designed for your vehicle and engine will not only sound good, get better performance/mileage, but will also be legal.
