I'll add some photos later. I just replaced the muffler system. Later, I'll look into replacing the H-pipe with a X-pipe.
I bought the Borla Model #140038 Stinger Quad Round Tip system. I ordered it myself and had it delivered to me at home, big 52 lb box. The box barely fix in the coupe.
Along with install at the dealer, I paid $1080. It was well worth it though!
I noticed yesterday that the throttle is much smoother now, and faster too! Borla states that you can expect gains of 7-10% HP. The noise is just fantastic, loud too! It has that real deep throaty V8 burble. I like it much more than clips I heard of the Corsa Pace Car system.
