Subaru 04-07 STi Stage 2 Power Package w/V3 is rated 4.7 out of 5 by 97.
Rated 5 out of 5 by from Subaru SS 3" Downpipe I was surprised how well this pipe breathes! Power increase is obvious and fitment is spot on. Very stealth in the sound department with a stock muffler but still a very noticeable back pressure reduction. I chose this pipe for the quality I've seen in all of Cobb's products but also for the other not so obvious features. For example, the welds between the casting and the stainless extrusion have more than double the welded surface area of the competitors pipe. The cat is down low and keeps the under-hood temps down. Should I ever need to replace the cat, its location under the car makes replacement (at any reputable exhaust shop) easy.

Rated 4 out of 5 by from So simple! Been riding around with stage 2 93 map for about a month now and boy what a difference. Those who are hemming and hawing about it because of price, just pull the trigger. It's worth it. It's now even easier to pick one up since Cobb has partnered with Affirm, so you can make payments on it instead of dropping a big chunk of change all at once. My only quip with it is how astronomically off the dyno feature is. As you'll see in the attached image, it's not exactly accurate, seeing that my only mods are turbo back exhaust silicone inlet pipe, and an sti intercooler...

Rated 5 out of 5 by from Can't go wrong with the Cobb! If you're looking for an easy & effective way to tune your car, this is it. The ease, design & capability is outstanding! I used it to custom tune my Legacy GT & it went perfect. You also look 2x cooler with a bunch of moving gauges when your driving

Rated 5 out of 5 by from More Power!!! This is the second Accessport I have purchased. The first was 11 yrs. ago for a 2004 WRX. This one is a lot better. Took 5 min. to save my factory settings, and 5 minutes to put in the new map. All I know is before the Accessport my automatic Forester XT would not squeal the tires, and after it did. Extreme improvement in acceleration.

Rated 5 out of 5 by from Thoroughly impressed with this system The pictures do not do this exhaust system justice. It is beautiful, with impressive welds. It is as much a work of art as an upgrade to the car. It is actually a shame that most of it is underneath the car, and remains unseen. This was surprisingly easy to install, and fit perfectly. I was more than happy with the new sound this exhaust produces. though louder than the factory exhaust, it has a very nice growly rumble to it, and as promised in the description, it is not an obnoxious noise you so often hear from other after market systems. I highly recommend this one, and only wish I had upgraded years ago!

Rated 5 out of 5 by from Cobb ap 05 lgt wagon 5eat I didn't realize that the ap was already on my car. I bought thinking I would get some improvements to the existing mods my car had. Previous owner gutted the up pipe and down pipe plus put a pulley on it. I enjoy the product even tho I don't have it hooked up to my car all the time. I will eventually get a e-tune, road tune or a dyno tune. I'm getting headers and tge sf intake this coming week and will get the catted downpipe in about two weeks. I hope I make some good power and have a nice exhaust rumble even with the stock mufflers. I'm not sure what others are running 0-60 on the ap but mine is really slow 7.1seconds. I really hope to improve this time as well. I'm wondering if altitude has something to do with the slow time. Thanks for a great product Cobb

Rated 5 out of 5 by from Perfect I've had this exhaust for the last month. I commute every day to work and have a 1 year old so super loud and drone were out of the question. This exhaust is awesome. Perfect sound with no drone. I can hear it but nothing like some of the other exhausts for the Rex. Sounds awesome at WOT.
