Really excited to have the Blacktop Aero and Byrson R combo. I don't know of many people who have both. I decided to go for the carbon fiber one because, well I don't know. I think I would regret it if I didn't.
I installed it there because I found out (the hard way) that the brackets for the diffuser hit the exhaust hangers. So I put the bumper back on and went there to modify the brackets.
With a stock DP it is pretty quiet and sounds really good. For the money I think it's a great exhaust. I'm not really sure why more people don't use it. With my catless DP it is obviously much louder but not ridiculous. There is a little bit of drone and this is probably where having a more expensive exhaust would help, but if you are cruising at 65 it's fine. It's at 80 that it becomes pretty loud. I think I will get a new exhaust eventually but if I'm going to I'll probably get something more exotic like the Milltek or ARK exhaust. I just can't justify paying well over $1200 for an exhaust right now.
Cfenning has an ARK exhaust on his hatch and the drone situation is handled much better than this exhaust, but it is actually louder outside of the car.
Small update... I used up my last free oil change from the dealership so I decided to change things up. I switched to Shell Rotella T6 5W40 and I'm loving it so far. It feels like it turns over easier and is a bit smoother. I can't really tell much else about it but it seems like a good choice for me going into the summer months in SoCal.
I also just installed Hella horns today. I'll post up some pics and video of how they sound. They are very loud... I may eventually paint them white but I'm liking the red for now.
Got a detail for the summer thanks to David at Watershed Auto Care in Simi Valley! Here's his website WaterShed Auto Detail. You can also look them up on Yelp and Facebook. David is an expert detailer. If you are as OCD as I am with your paint, you should hit him up. Tell him I sent you and I'm sure he'll give you a solid deal. He has owned Subis in the past and loves working on them.

3rd time is the charm.
It has been quite a long time since I’ve actively been on here and have had any desire to really work or care about cars/car work.
I recently got rid of the rebuilt title 08 STi I had and picked up this 2011 sport tech mode from a military fellow. It’s been sitting in...

My first journal of my first STi, a 2011 (RIP) is here. Scargo's First Subaru: 2011 STi Ltd Sedan DGM
Many of the parts from it went into this, my current car, a low mileage '08.
Suspension modifications, chassis stiffening, etc...

Well Hello!
My name is Rob, and this was my first new car. I kind of bought it on a whim, and a little suggestion from my wife. Originally I was going to buy a Focus ST, but she...
