Do bloated exhaust pipes do anything?

Believe me, exhaust restriction isn't what's causing a stock Dodge Neons and Honda Civic to be slow.

<< Increased piping size all the way from the manifold can increase horsepower. However, the gains are usually minimal. Best to remove the cat. converter, too. >>



Modern cats do not have a whole lot of restriction, especially for a 4 cylinder; though a turbo engine would benefit a good deal more. People who "gut" their cat (by removing the innards) regret it too, as you end up with a hollow-sh*tty sounding car.

I tried to reall all the responses the best that I can. I have always got the impression that increasing the size of exhaust only increases your top speed? As someone mentioned that it gives you most power at the higher revs. What if I wanted to improve the accleration of a car? Does it mean I shouldn't touch the exhaust or a "small" increase in size will also help accleration.

<< best mod? a stuffed pikachu or whatever on the rear deck. Thats worth like 10hp right there plus its fun to make em stare at drivers behind u. >>

Proper is the keyword here. Going too wild on a N/A car will definatley hurt your low end power. A modest increase might help power all around, a slightly bigger increase might give you more highend but hurt the lowend some, etc. So really you need to talk to others that have the car to find out what works best on that car. That will determine what rpm ranges get more power and what get less, if any at all. There is no set formula, its trial and error on a per car basis

Thanks for answering my question Soybomb. Sometimes I don't understand... Well it may works for the US since radar detectors are legal over there. What I don't understand is why people put in a say a bloated exhaust as it clearly increases "top speed" which sacrifices "accleration". Cops will be all over ya by the time you reach that 200km/h mark :Q I'd rather have a car with good accleration which I think is more useful.
