I want to gain a little more acceleration so i can take off quicker like when going on the highway but i dont like the ones with large mufflers so i am thinking about getting a flowmaster exhaust installed on my ex. Even though it is automatic will i still notice any performance gains, even slightly? I figure since the pipe outlet is like the same size as the oem one that i will still have the back pressure needed and get the benefits of the high flow exhaust pipe too.
also if i get that installed should i also get a new aftermarket intake put on too? is it better to have both or would it be a waste and should just get the exhaust. becuase i hear the stock air intake system is more efficient thatn a short eram or cold air aftermarket one.
Flowmaster and 4 cylinders are not a happy marriage. Your car will sound like crapola!!! Don't do it. Also, in order to really get the best performance out of your engine you need bigger pipes to let the air flow better. You're restraining the air flow with little straw tubes so your car isn't performing up to par. You need to let that little sucker breathe. Like the person above said I wouldn't get the aftermarket intake either. A drop in K&N filter will give you slight acceleration and more MPG's and cost a lot less then an intake. If you must put exhaust, get a new header and open up the pipes some. Instead of the stock OEM pipe see if you can get a little wider pipe. True, it'll sound horrible but at least you'll have more air flow. More air means more power. Good luck with that though
