SPT Catback Exhaust at Russ' Garage, there were two things that I really loved that kept me going: the Look and the Sound. However, there were setbacks that I hadn't taken into account until the exhaust was on there and I had been driving it for a couple of weeks. Interior Cabin Noise, loss in low-end torque, and (as a result of that loss) significantly worsened performance and gas mileage. I had initially thought to solve at least the cabin noise with a resonator install, but the performance issue would still be nagging at my fuel gauge. Thus, I started brainstorming for an alternative exhaust setup. I figured I wouldn't be able to retain all that wonderful SPT growling, but I wanted to at least retain the look of the quad tips on the back of my Impreza. That's where an unlikely hero stepped in to help me solve things... the Subaru BRZ.
Russ' Garage was the go-to place for this project. Thanks to a fellow enthusiast who had just installed a Perrin Exhaust onto his BRZ, I was able to nab a stock BRZ catback exhaust and start working with that. Russ laid things out and checked to see what could stay and what would need to be modified and got a simple solution set up. The system would retain the stock Impreza mid-pipe up until a few inches ahead of where it clears the rear suspension. From there, we cut the tail end of the BRZ mid-pipe to pair with the stock Impreza mid-pipe. Then the hangers on the BRZ muffler linked flawlessly into the 5-Door Impreza's existing setup (like it was made for something like this) and buttoned the rest of the exhaust up!
The next part really finished things off, though. The tailpipes were too short to make it to the edge of the bumper... and I still wanted a quad-tip look that I had on the SPT Exhaust setup. I tracked down lookalike exhaust tips from RedTail Performance, double wall, angled cut, polished chrome finish, and started cutting into my bumper to accomodate the space. A good friend of mine with a WRX helped me weld the tips on to the BRZ tailpipes and, after finishing up the edge of the bumper with some crafty use of Door Edge Guard, it was finished!
This exhaust certainly looks the part. It's integrated into the bumper, so not only does it look more like part of the car, but it's also brought back my stock ground clearance, which is helpful when I want to be a little more adventurous. Thanks to the smaller diameter piping in the BRZ exhaust, there's no loss in power or low-end torque. As a result, fuel economy has returned and I easily average 33mpg combined city/highway driving. Cabin noise is nice and quiet again, so my passengers are thankful for that. Overall, there's a long list of things I enjoy about this setup as it just makes more sense for a car like this.
