Are there any advantages or disadvantages too the SPT exhaust? I have been trying to find some articles on it, but I can not find any on the subject. Anyway lemme know.

Advantage = Quiet aftermarket exhaust
Disadvantage = Weak power gain

It all depends on what you're going for. You don't have to replace the stock catback if you want to add a downpipe and get a stage 2 tune, but if you do upgrade your catback to something that's more free flowing you can squeeze a little more power out of your tune. Supposedly, the SPT catback is not as freeflowing as other aftermarket options but is better than stock.

I have it on my 2010 hatch. The sound is excellent if you want a deep growl without a ton of volume. It's considered semi-quiet for an upgraded catback but it still sounds mean and is definitely louder than stock. I believe it's 2.5" piping and most prefer a 3" pipe but I don't have any experience with the difference when it comes to tuning potential. It's also a little pricey in comparison to some other options and it isn't all shiny and fancy looking.

One advantage that may or may not be an issue is that it's technically a stock part available as OEM. Subaru can't really complain if it's on there and law enforcement is less likely to be able to write a viable citation.

For me, the sound was the biggest reason to get the SPT although the added tuning potential over stock is a perk too. I considered Invidia and TurboXS as well. If you want the max available power, get something else. If you want a great sound without attracting a lot of attention, go SPT.

Really what he all said is absolutely true. I love the sound of them too and hate attracting too much attention so I'd suggest this exhaust or a Perrin

^I love both these guys. They are championing the quiet Subaru exhaust. YES!

You should hear my Zero/Sports! I think its quieter than the SPT one. NO HIGHWAY DRONE FTW!

LOL! I would love to. I swapped my 2.5i exhaust for the 09 WRX exhaust. Doesn't sound like much at speed or at idle but on a cold start, it rumbles just enough for my liking.

I am looking more for a significant gain in power. So it sounds like I should not get SPT.

Bah...I remember when companies didn't make horizontal-mounted exhausts for the EF9s. Still not super popular but they look a fair more decent then the motorcycle-inspired fartcans.

Is SPT going to come out with a downpipe? I do not want to give Subaru a reason to not cover my car, but I want to mod my soob so BAD!

If you want gain in power, I would go after market dp and cbe and a set of equal length headers. Aftermarket products are not as widely available for the 08-10 models as they are for the 02-07 models.

Subaru wont cover your warranty if the aftermarket product is the cause of the problem.

Jeff - You are sorely misinformed. Yes Subaru CAN void your warranty due to aftermarket parts BUT Subaru has to PROVE that the specific aftermarket part did indeed cause a malfunction. 2.5i (Les) knows a lot about the legislation that goes into this. I'll get him to fill in the blanks as I am still in the dark (my law professor would have my hide if he heard me say that).

^that's what I was told by another Subaru owner. You should fill in the blank for us Michael... it'll be something good to know seeing that I have 2 more years on my warranty

Yeah it isnt supposed to exceed 92 dB while on WOT but still have that burble down low.

SPT will not come out with a downpipe for their car, they never have and probably never will. I believe it'd be a lot of liability that goes with it (ECU Reflash and damaging motors if not done correctly). I know for a fact that we wont honor warranty if your car has been modded or if something is wrong and you try and revert it back to stock and we will probably report you to SoA.

Wait so tuning you're car after a mod can damage the ecu? Also if there is any mods and something goes wrong the warranty will not be in affect?

I meant that Subaru wouldnt make a mod to your car that requires ECU Recalibration (example downpipe). It is really up to the dealer but most of all SoA. They make the final calls on warranty. If they feel like they shouldnt be the one covering they wont. I know Mazda has some BS about modding your cars too. I know a few people with blown bottom ends and they blame it on small power mods or something and they tried to not cover it under warranty.

So basically if you mod you're car if they do not want to cover it they won't.

Why do you think I've stayed away from the engine all this time? I don't want to deal with all of that again. Remember when I blew my turbo in the Beetle, Pat? It could be a lot worse than that.

I drove to work today in an $80000 Mercedes and I'm going home in a prop car from Fast and the Furious… my life is over!

HOW???

So stick with cat back exhaust until warranty is up... Can i throw a cold air intake without that affecting my warranty?

Yes even SPT makes their own short ram intake but keep in mind that this does absolutely nothing for your car. Your engines intake is over engineered and has no real gain unless your car is over 300-350 hp to the wheels.

Howd you get to drive a prop car lol

Bah. warranty shmorranty.

-If you add a CAI, you need to have the car tuned and if there is an issue and Subaru can trace it to the CAI and/or tune job then they won't have to fix it.
-If you add an SPT catback, any warranty claim can't be blamed on that part unless it was installed incorrectly.
-If you add a CAI, downpipe, and SPT catback, you have to have the car tuned and again if there is an issue and Subaru can trace it to these modifications they do not have to fix it.

Those are the risks you take. Myself... I trust that my rex will hold up as long as I'm not a fool with it and get my mediocre mods installed and tuned correctly. I also am willing to pay for my issues if there is a problem because well, it was my choice to take the risk.

I installed a stage 1 map via accessport and so in theory my powertrain warranty is now already shot prior to my downpipe, CAI and protune. I won't cover it up if I happen to have an issue but I don't expect one and I would hope our dealers wouldn't raise alarms. Subaru makes a pretty reliable vehicle and if you take care of it, you're not likely to have a problem. Just make sure you have the means to fix it on your own if something major occurs.

From what I read cai with a tune will give you're car more power than a short intake.

I was under the impression that spt parts were designed to stock specs (intake diameter) and such In order to make a tune not necessary..

Sunny if you have them throw on an spt part at purchase of a vehicle do they install and say here you go congrats! You no longer have warranty? Or do they warranty in considering they did sale and install?

This discussion cannot be rocket science. We've had the damned engine since the dawn of time and no one has an general answer? C'mon...if I knew more about boxers, the law would be laid down.

TORQD, TWRX05, AWD>FWD...where is your input?
