Correct. You probably would have been well served just getting an "axle- back" exhaust, which pretty much just liberates a couple of kW and gives a nice note. Modding an exhaust (cat-back) almost always makes the car louder and more annoying, than any satisfaction you may gain from the meagre power increase you may get. I've only heard a couple of exhausts that were worth it, for power gain, noise increase, exhaust note/tone.Gav. When I got my 3" redback cat-back exhaust i had buyers remorse. Will the chicks think i'm an idiot? will I wake up the neighs? Will it damage my engine? TBH it lasted a few days. I occasionaly get a little kick when I jump out after a good long run and smell almost like...smoking metal? At the end of the day, when I launch Jenna, the joy I get is worth it.
