if i just got a performance muffler from the local muffler shop. would it be better than stock?

Question

i want a muffler to be a littler louder and little more flow than stock. can i get this at a local muffler shop. the flow is the most important as i have a big foot.

Answer 1

louder maybe. performance...not noticible. better get your carb rejetted and add headers. BTW any smog guy might frown on pipes and headers.. save your stock setup for smog checks

Answer 2

What exactly do you want flow for? Because flow isn't going to increase your performance on a stock car at all. No matter what the advertisements say. Better flowing exhausts in combination with other mods will add horsepower. For instance a better exhaust won't allow any more air to flow if your intake allows only so much in. Even if you do intake and exhaust it still wont neccessarily mean any gains because their are other factors, like your cam, the lift of your valves and how much air they'll let in. You have to always think of your engine as a giant air pump, the more air it flows the more power. But if you ever were to sinificantly increase the air entering your engine without doing anything else your engine would run lean which would increase temperatures and destroy it very quickly, so you'd have to have more fuel to make up for it, bigger injectors, higher flowing pump. Of course in the mean time the pcm would be freaking out and probably putting the car in some kind of limp mode thus just making the car slower. Of course you'd never have to worry about any of those factors because a mere exhaust much less a muffler isn't going to do crap performance wise or flow wise. You'll just have a louder car. Remeber, the exhaust still has to flow through your catalytic converter and that pipe. And even if it didn't and can only put as much exhaust out as air it can take in.

So to answer your question, no a high performance muffler will not be better than stock 99.9% of the time.

Ofcourse if you had a high performance engine that was practically joking on its own exhaust gasses and then you added a better flowing exhaust you would see massive gains. It wasn't neccessarily that the exhaust added power, it was that the old exhaust was so restrictive to the other mods and the rest of the motor it was eating tons of power. The companys that sell mufflers and intakes etc. use situations like these to test their products so they can say that it adds crap loads of power.

Thinkn of it this way. You have a stock car and you stick a potato in the exhaust, the car has very little power now and nearly dies. You take the potato out and put in a POS high performance muffler and see great gains. Did that muffler really help you? No. Advertising fooled you.

Answer 3

It would sound better than stock, If you are looking to gain a little hp's and mileage. Than can i suggest a high flow catalytic converter, cold air intake, and flowmaster 51 series is a good sounding muffler. Remember it has to breath as good as it exits for maximum performance. Good luck

Answer 4

you will possibly might desire to redo the piping from the catalytic converter back, probable, yet a great form of Mustang V6 vendors placed GT "takeoffs" on their automobiles as a fashion to get a splash "throatier" exhaust notice. What would possibly not artwork is the exhaust hangers - the failings that connect on your vehicle's chassis to assist the muffler. i might look for a Flowmaster or a Magnaflow muffler it quite is made to in wonderful condition your vehicle, particularly than attempting to weld or screw stuff into place that would not belong there.

Answer 5

yes and no they would want more money then the hp is worth and you would need a cold air intake/short ram filter to go with it or it will not help to much at all

Answer 6

It might not help perfomance wise enough to notice, but it'll sure sound cooler.......

FLOWMASTER LOVER.

Answer 7

nope
