BRZ TRD
 

After over a year in my '13 SWP BRZ limited, I decided it's time for some performance parts. Being conservative in nature, I was attracted by the TRD exhaust and cold air intake. The sound (a little deeper) is just right to my ear. And it appears there's a minor performance boost as well. So I just pulled the trigger. My local Scion dealer (just down the street from my Subaru dealer) will install the parts and I'll get the mfr warranty on them. Can't wait!

I wouldn't bother with the intake. Aftermarket intakes make no difference on these cars.

I'm no expert, but from what I've been reading an aftermarket intake can get you ~5 hp, but an aftermarket cat-back exhaust won't get you anything without doing the rest of the exhaust as well.

Even if you could get 5HP, you wouldn't feel it at the wheels. Typically it's ~1HP or less with aftermarket intakes on these cars.

Read through here and the linked threads before spending ~$500 on something that's more cosmetic than anything:

The TRD, at least on my car, is a lot deeper down low

If I were you at least plug up the sound tube in the foot well to remove extra loudness and keep the OEM intake

I have both the intake and the exhaust and like them. I recommend running a modded snorkel with the TRD intake.

You can get same, if not marginally better gains from a $50 drop in filter like K&N. Your better served going that route.

Aftermarket intake tends to shift your power band higher into the rev range, hence your "5hp" gain but you won't get it until you hit close to redline. Your midrange will goto shitz. No thanks!

That's the route I went, got a Green Filter drop-in. Plan to go FI one day so I'll mess with the intake then.

Plus to truly gain any HPs you would have to tune the car. Drop in filter is the way to go.

Seems like a good route would be doing a header, tune, and a drop in filter. Doesnt change the sound too radically with the header and stock exhaust.

Boy, everyone's pouring a lot of cold water on this. I have no illusions that this will have anything more than a negligible impact on power. I like the sound and the look of the TRD exhaust. And it seems appropriate to add the matching intake - it also looks nice and deletes the silly sound tube. Nuf said.

You're better off grabbing one of these if you want to delete the sound tube: http://perrinperformance.com/i-13324...-fr-s-brz.html

There is still some people get better HP with TRD intake.

Thanks.

It's your money, do whatever you want. People are just trying to help you from wasting it.

From what I have read, the best bang for buck is a tune and a header.

For me the best bang for buck is a supercharger with a mild tune.

:iono:

Does anybody have suggestions for a reasonably priced header? Also, will unequal length (UEL) vs equal length give me some of that boxer rumble? Lastly, I need to keep my cat. Is it normally integrated into the header? I remember seeing that from speed factory and thought that was interesting.
/sorry if this is considered a threadjack.

There are 2 cats, one in the header and one in the front pipe. I assume you want to keep both? You can get aftermarket headers with cats. However they are all going to be the the more expensive ones, I believe the cheapest catted header is around $800, maybe more.

They come in both UEL and EL. From my understanding UEL will give you more of the boxer rumble, EL will give you more pure power.

If you can stand to lose the cat in the header (you'll still have one in the front pipe) the OpenFlash Header is the least expensive I've seen and gets good reviews. It's UEL but again it is catless.

It seems that many modifications cost a fair chunk of change. To change power makes some sense but to change the sound of the intake or exhaust is quite expensive, considering the modest improvements. In order to get real power, short of a turbo, you'd need a header back and a tune. That isn't inexpensive, particularly for those if us who need to keep our emissions under control (hence, no cat deletion). Still, I'm glad the options are there.
