I agree, but if you look cars in a practicle sense, it's not practicale to have a car that'll go over 80mph in the US, but just about all of them will. I guess it just depends on what you're into. Down here in South Florida it's common to see originally N/A cars with turbo setups. Our cars are quite underpowered. Doing the exhaust and intake work will not get you close to what these should have. They need at least 20 more hp. You might, if you're lucky, get 10 to 15hp at most out of doing the exhaust and intake.
As far as doing an exhaust, I don't want it to sound like a river in fact I don't want much sound out of it at all. but more flow would be nice. I want fuel mileage not so much power. I drive 80 miles a day for work, any ideas. It's all stock besides wheels
I installed a cheapo ebay brand short air ram and got bigger results then expected, http://www.ebay.com/itm/BLUE-Short-R...item43e5e369e2 this comes in blue black or red, and is like most short air rams only expected to add a max of around 13 hp to the engines peak performance. However recently after putting the car on a dyno the Whp topped at 174, a whole 29hp more then stock for my 2013 elantra GT, which is great because it was below 50$, took a max of 10 minutes to install, and adds a nice deeper tone to the stock engine sound. next step for me is a stiffer suspension though, followed by an exhaust system.
