The removal and install was no challenge at all. Some penetrating oil, basic tools and a couple jack stands are all you need. Make sure to get new hardware(turbo-exhaust bolts+nuts and gaskets for both ends) I also used molyB because I like to be extra.

Car performs better than ever after the install and after 2 weeks of driving it, I still have an ear to ear smile, listening to all those turbo sounds. Only complaint would be that the downstream O2 sensor location was back further than stock and took some creative wire relocation to make it reach.

A definite needed addition 2 your exhaust system. The best parts are the performance it adds when tuned, as well as sound enhancements. Has a nice open bell mouth 2 expell gases, but I would definitely recommend getting an external wastegate 2 minimize turbulence leaving the turbo 2 fully see the downpipes potential!😎

Installed the COBB down pipe along with the Invidia Q300 catback exhaust, tuned with COBB accessport stage 2+ SF. Took a little time to find all the screws to the stock heat shield. Other than that everything else was pretty straight forward. Loving the sound and performance of the new exhaust. Definitely recommend this product.

When first pulling it out of the box you can really see the craftmanship that went into making it the price it is, and why it’s a high seller. When comparing it to the stock downpipe you can really see how much the stock one restricts the flow. The diameter is significantly bigger, and the material and quality is far more. The install process takes time, but isn’t frustrating as long as you have the proper tools and setup for the job. I’d definitely recommend buying extra screws however, gasket, donut ring. You can definitely hear a change in the tone(deeper) and throatiness compared to having just a catback(Cobb) setup. It’s not much louder, but does give it a slight increase in the two I just mentioned. It sounds great when you really get on it, and gives off more pops when both up and down shifting. When flashing to the stage two tune you can definitely see a performance gain as it pulls harder in each gear and puts down more boost. I really enjoyed the car a lot more around twisty hilly roads. The power was there when you needed it. I’d say it’s well worth the upgrade

Q: Fitment Inquiry wonged2 months ago
I have a 2014 Subaru Impreza WRX (sedan, USDM). I'm currently running a Tomei Expreme Ti catback exhaust system. If I'm understanding correctly, the following items would suffice in order to install the COBB Tuning Downpipe without any issues; turbo to downpipe gasket, oem downpipe to 3" catback adapter, downpipe donut gasket. Can you please advise if I'm missing anything? Thank you in advance!

A: You are correct! The only other item that I would recommend is a 3" 2 bolt gasket for the catback side of the adapter.

A: Should I use the Invidia instead? Or would that need an adapter, too? Is this adapter something a standard exhaust shop would have?

A: The downpipe tapers down to a 2.5" so it will not fit and unfortunately, we do not sell a downpipe with 2.75" diameter.
