The biggest thing that needed to be changed were the hangers. On the 3rd Generation design for the Impreza/WRX/STi 5-Door, the hangers point forward and backward. On my 4th Generation Impreza, they point side to side... so in order to fit 'em, we needed to redo that system. Russ cut the original hangars off, sanded off the rest, and actually used the parts he had just cut off to start making the new hangers! It's a stainless steel system, so things were a little tougher to work with, but RG did not disappoint. To complete the fitment process, we added 2 inches to the mid-pipe so the tips could be revealed a little better under the bumper. This also allowed us to clear the rear sway bar, which was in the way at first. Because of this placement, and since there wasn't any cutting done to the bumper to accommodate it, the bend in the mid-pipe to go underneath the rear suspension lowered the ground clearance a bit.
Once it was finished, I took it for a spin right out of the garage into a snowstorm. The snow was deep, fluffy, and in need of some shredding, so I found an open parking lot and went to town on it. The sound was great! Just what I had been hoping for! I was a little worried about the sound inside the cabin, but didn't think much of it. After a few weeks of driving with it, that interior noise was starting to bother me and my passengers, especially those unfortunate enough to sit in the back seat. Without a resonator on the exhaust (since the SPT Catback doesn't have a resonator) all the sound that a turbocharged engine would usually help muffle was now roaming free in my eardrums. I hadn't taken all the variables into consideration. Still, the car sounded great, the SPT quad tips off the back end looked fantastic, and I found myself turning quite a few heads.
In the end, I ended up removing the SPT Catback Exhaust and built another system based on my stock exhaust and a BRZ stock exhaust. Again, Russ' Garage went to work on another crazy idea of mine, but I'm much happier with this new system as a whole. I still have the SPT Exhaust stored away, so I might revisit this idea if I can figure out how to solve the issues I had with it, but for now... my car just can't handle it!
