Default Best intake/cat back combo

It's income tax time and I have the Aem with box cold air system and the invidia Q300 cat back picked out. Anyone have a better "bang for the buck" combo idea? Any ideas on the tone? Realistic gains with or with out the access port?

You won't see very many gains from a catback. The real power comes from replacing the downpipe.

STOP RIGHT NOW.

Read this: Unabombers Manifesto. AKA the first thing you should have read if you want to know anything about your car.

Then understand there is no "best." And without a budget or more idea of "income tax time" we can't have any idea what you will pay. Also understand intakes do little, and if you want to use a Cobb OTS map you'll need to stick to Cobb's SF intake.

And BE SURE you understand that you need some form of tuning for an intake unless you like blowing up your motor and paying $5000 minimum for a new one.

Gains without the AP is your engine will blow up with an untuned intake.
Gains with an AP are posted on Cobb's site. Research is key here. Intake makes almost not difference, don't let the manufacturer hype you with "17 HPs OMGZ!"

You don't even say if you have a hatch or a sedan. Cat back exhaust is extremely different between the two.
For example. The Q300 you quoted is known to drone in the hatch version
http://forums.nasioc.com/forums/show....php?t=2310459

While the sedan it sounds pretty good.

Just read through this thread for a loooong time and get an idea of what is good for your car.
http://forums.nasioc.com/forums/show....php?t=2119289

77 pages of what cat back is the "best"

Mainly you have to research for yourself, we can't tell you what you will or will not like. It is all an opinion.

All true except Cobb makes OTS maps for the AEM CAI on 08+ as well.

Skip the intake and the exhaust and get the accessport and flash stage 1. That will be the safest bang for ur buck and ur motor won't blow

This

To the OP
Intake will give minimal if any gains. Catback will yeild nothing. These mods will basically just make your car sound different.

q300 + stage 1

if you already have a cobb AP

then... get a downpipe instead of intake... Best bang for your buck
huge tq gains, great turbo spool noise, compliments catback!
DO IT

So no intake or exhaust, just the Cobb AP?

Intake and catback will act as noise-makers and offer zero gains.
You'd be better off getting a downpipe and a tune.

Because motors blow up all the time from having an intake but not tuned for it..

Is it bad for the motor? Yes. Will it kill it? Probably not.

Continue to exaggerate.

This post is stupid.
Exaggerating or not, why let him risk the motor on his brand new car? Better to explain the risks and present worse case scenarios so he can make an informed decision from there.

I like that idea. I just want safe HP... Well as safe as it can be. I'm leaning towards Cobb AP, some intake, Cobb downpipe and the q300 catback.

Does this sound right or am I flawed.

I'm coming from a back ground in high performance NA engines (sport bikes). So number one to me was always open it up and let it breath. Turbos are new grounds for me.

You have the right idea, but our cars are a little different. As stated earlier, the best bang for the buck HP wise is the downpipe and tune.

The intake will offer little to no noticible power and the cat back will offer 0 besides noise.

It has not been asked yet but do you value your warranty? If so the cat back is the only thing on your list that will not cause a claim to be denied. Just a heads up. If we are presenting worst case Ontarios, abusing your car at stage 1 or 2 can lead to a broken turbo or piston. Very worst case is a spun bearing. These are things that can happen to any motor when adding power.

These are roughly $2k to $6k fixes. Just know that.

Read through this below thread to get an idea of the **** that can happen on upgrading your car. You will be left out in the cold by SOA.

I wonder which opinion holds more weight....mine or yours? Thanks for being critical of mine, I'll remember that when it comes time to prepare my Christmas card list.

Yeah warranty doesn't really mean much to me to be honest. But I don't want to do unnecessary damage either.

Stage 1 and 2 are very safe power levels. But just understand, you are increasing the power of the motor anywhere from 25%-35%. This is power levels the engineers did not necessarily design for. It will increase the wear of your engine and power train. Just be sure to keep up with maintenance and do not excessively beat the **** out of it (launching, doughnuts, "drifting") and you should be fine.

About the intake thing, I think people are kinda kooky over it, I had an 08 wrx and put a magnaflow cat back and a injen cold air intake no tune and it was completely fine in fact it was more responsive and ran better, plus I got better mpg, now I'm no tuner pro but I think that my car was good the way it was and the dealer took it as it was on a trade for a 2013 wrx that came from the factory with a full spt catback exhaust. So my point being a then might not always be necessary but wouldn't hurt.

Say what you will it worked and the car ran the exact same way as it did when it was stock, other than te response in the pedal.

It also came with a short throw shifter which made a huge difference in the fun factor of driving a Subaru.

Oh boy...

You don't run a CAI without a tune. Not knowing this shows you haven't researched (at all).

This is the CAI I have (and put on IN THE PARKING LOT of the place I was getting it tuned for)

http://www.hptmotorsports.com/subaru...x-and-sti.html

I have the Borla catback exhaust and Cobb downpipe and love the combo.

Enjoy the car, but let this serve as a lesson to you to research and learn about your car. These cars are very very sensitive to modifications without a proper tune.

Like blow up your engine sensitive. Done right however, you can have reliable car with mods. I have 105k on my modded STi and it runs like new.
