After looking at so many exhaust systems and looking at my own stock set up, the only difference I can come up with is weight and with a little ingenuity,( ie. stripping the airbox, taping the manifold) a stock system is less expensive that lends to more versatility. Does anyone agree or disagree and why?

Hmmm there a some aftermartket parts that are garanteed to make power over stock.

If you combine aftermarket parts with some form of tuning, you'll make your money worth while.

You haven't looked very far then

If I pay five hundred for an intake, 100 for a throttle body spacer, a grand for a header another 100 for a test pipe and 2 grand for a cat back and I'm only on the high side of 20 - 30 more horses seems wasteful. That is 3700 bucks that coulda bought a decent turbo. I guess what I am asking is for someone to make me a believer before I start spending a bunch of money for name brands and no real power...

So you already know the answer.... Its like spending $$ on nice good looking wheels that if not chosed correctly degrade the perf of the vehicle.

I agree sort of.... My S has intake/header/high flow cat/exhaust and a tune. Unless you just love tinkering with your car (as I do), then stock will keep you happy. There aren't enough gains in NA mods to spend the $ for nice parts if you're focused on performance. It's more about the "build" and making your car yours in a way than the performance w/ NA IMHO. You may enjoy $1.5k in suspension mods much more!

Plus, I think the stock exhausts look best...

Why would someone need to make you a believer of NA mods?!

If you want some sort of proof of bolt on gains, look in the Official intake, header and exhaust threads. There are dyno sheets. There's also a thread about people posting their dyno numbers, whether they are FI or NA.

And/or search.

dollar for dollar FI will net you the most gains, going basic NA the main thing is gearing for better acceleration and a bored throttle body for snap, other than that you are dumping huge amounts of money for tiny increases, just go FI...

I've ran several exhausts, and I decided I kind of like stock AP1 with a test pipe the best. Other than expensive high end ti singles of course..

i have a prm intake (for sound and 'cause my stock setup is incomplete), a megan header (just got it 'cause it was cheap but the gains aren't even worth the install in comparison to stock), a highflowcat (the bottleneck), and i'm going with an aftermarket exhaust (not really for gains but 'cause my stocker is ragged as hell). so, i can rationalize my i/h/e purchases somewhat but i really think the best way to go NA would be gears/testpipe/single-exhaust/bb-throttlebody...
