For full features; Go to HELP - How to increase horsepower without replacing engine
Here's the thing: I have a 2003 Pontiac Grand Am w/ 3.4L auto 4-spd v6. I
am looking to most importantly improve horsepower, as well as possibly
improve fuel economy or even do both. I was looking at getting a Flowmaster
exhaust system and talked to a guy that told me I needed a "Cat-back"
exhaust system. But I don't think I should just take one guy's suggestion;
I want to make sure that I do the best thing. I really don't know a WHOLE
LOT about these kinds of things, so I need help. The thing is I am looking
to spend no more than $800 total, whatever I end up doing. Any advice on
what to do and how to get the most out of my $800? Any responses will be
greatly appreciated, thanks.

There are a million threads already like this on the boards. Without us
regurgitating it all, just do a quick search through the forums and you'll
find many a thread on "adding cheap horsepower" etc etc...

Okay thanks, and sorry about that I'm new to this.

no worries... but most of the info is already there... a bit of effort
saves you waiting... and saves us arguing all over again about who thinks
CAI's and cat back exhausts are useless or otherwise. :mrgreen:

Even as a car enthusiast I don't see it a great idea to spend $800 on your
car. That'll get you an intake, catback, and a few other things...barely
noticable over a stock car performance wise.
What probably isn't in the other threads on the site is a torque converter
with a higher stall. I don't know a ton about this particular engine but
most normal cars are set up to take you out of the powerband when the
automatic shifts. A higher stall will keep you in the powerband. For
whatever reason I don't see a lot of non-musclecars doing this mod, so I'd
definitely talk to a mechanic. Plus it's going to hurt your MPG.
My other:2cents: ? Take the money, buy GOOD summer tires and a helmet, and
go to some SCCA autoXs. They're about $35 to enter, one car at a time
races on an empty lot made into a track with cones, so it's completely
safe. Believe me, there will be plenty of people out there with slower
cars and probably 10 other first timers who don't know what they're doing.
5 race events and you'll be a much better driver, and your improved skill
will make you a hell of a lot quicker than $800 in bolt-ons would have.
Plus it's fun as hell.
