whats the best but still cheap exhaust system for a ‘79 GMC jimmy
I would suggest that you take it a muffler shop and have a new exhaust put on. New duals with 2 inch pipe and a pair of good mufflers or glass-packs. I would use the glass-packs It will be much cheaper than than those male order kits and the outcome will be better.
What should i get: Carbon Fiber Hood/ Exhaust System/ Touch Screen stereo ?
ilook at a car as nothing maore than a way to get me from point A to point B that much quicker. i would bet the 750 on dullahan in the BELMONT
I have a 99 2 door tahoe and i have a flowmaster super 44 and i want it to be a little louder how would i go about this? i dont really get the difference between a cat-back and a dual exhaust system for some reason it confuses me.
A cat-back is just an exhaust system that leads into the cat, a dual system never joins together. But I think you're referring to a Y-pipe vs a X-pipe vs a H-pipe. A Y-pipe has both headers leading into a single cat-converter and then leading out through a single muffler. This system relieves back pressure in the mufflers, but has stock limitations in the cat. An X-pipe has each header leading into a separate cat-converter then the pipes join together to equalize pressure, before separating again into two separate mufflers (most effective system). Or the H-pipe (loudest) has two separate pipes coming off each header with it's own cat and muffler. If you want to increase sound go with the H-pipe and cut out the mufflers to make a straight pipe.
is there any simple way to fix it before it blows up the engine?
On an engine that is running, it is impossible to get water INTO the exhaust system because the exhaust should be blowing OUT all the time. If it sucks in, you have a timing problem. Someone is trying to take you for a ride.
Alright, i need a little help here. So I‘m going to give an example so that I can get a remedy to my questions. Thank you for your help! :DSo lets say you have a 1 inch exhaust system all throughout that can let out 10 litres a second (Thats pretty standard, right? I think.), and you‘re using a 1.3l 4 cylinder engine, and you‘re chugging along at 2000 RPM.So to my understanding;2000 RPM / 4 RPM (Ever 4 RPM all 4 cylinders have had one exhaust stroke) 500 RPM / 60 (I need the per second rate) 8.3 RPM x 1.3litres 10.8litres per secondSo clearly this set up has some back pressure equivalent to .8 litres a second since the exhaust can only handle 10 litres per second.Now I KNOW I‘m wrong since I‘m missing a few things; Speed of the gasses, how many RPMs it takes for all 4 cylinders to go throughout an exhaust stroke (I think I‘m wrong), and how to convert litres into psi, and what psi is needed to create a scavenging affect.
Statements: Cylinder capacity is the swept capacity, and can be expressed in liters That is the bore area times the length of the stroke times the number of cylinders All four cylinders exhaust once every two revolutions. (See engine displacement at pedia.) Your 500 RPM divided by 60 is wrong. It is not 500 RPM, but 1000 exhausts per minute. And that number is multiplied by 60 to get exhausts per second, not divided by 60. So, for every 2000 revolutions you get 1000 times four exhausts. Now things get complicated. The total cylinder volume is not 1.3, but 1.3 plus the volume of the head space. The engine needs space for the sparkplug penetration and for valve movement. We do not know at what pressure the exhaust system handles 10 liters per second, nor how much back pressure are willing to have Air comes in at some unknown temperature. It is heated in the cylinder, so when it is released it expands. We do not know the temperature of the exhaust gas. Added to the new volume is the volume of gas generated by the combustion process. There are too many unknown variables to allow us to generate a formula. In engine design, bench testing determines the numbers you are looking for.
I have a 1986 Chevy Caprice 8Cyl. 5L. Gas, Carb: VINH That has a exhaust system with a Catalytic Converters and a muffler.(Only one pipe) I want my car to run better and go a little faster. What should I buy? And can I upgrade anything else to make it faster? P.S. I just put a new holley carburetor in and the motor is only 3yr. old.
put on a set of exhaust headers with a dual 2.5 exhaust system and flowmaster super 44 mufflers, also get a KN air filter for your carb, that should give you a good taste of more speed.
I got a V6 with stock muffler/exhaust/etc and I installed KN for a deeper engine sound. I wanna run straight pipes. How much would it cost if i were to take it in for professional installation. And how much of a difference would it make if i were to run straight pipes rather than stock muffler/exhaust.
Don't go with straight pipes, it will sound like a ricer and you'll actually lose power. Get a Pypes H pie cat-back system and either the Pypes high flow mufflers or Ford GT takeoffs from a 2005+ Mustang. Sounds way better. Complete kit is under 500 bucks, another 150 for professional installation.
Is it because the back pressure is out, How do i know what it should be.
any time you make a engine breath better ex. performance filters exhaust intake ect you need to ad more fuel to the mixture because there is more air going threw get a chip is my suggestion can also try a higher fuel pressure regulator no need to rebuild injector unless your pushin 600hp with a turbo
