I have a i4 2010 manual im slowing starting to mod it. I want to get a full catback next but i cant find many that are instock other then magnaflows or takeda, but ive heard they arent as good since theyre the same as stock piping. Waiting for the megan racing dual exhaust. Also planning on installing a rv6 pcd with k tuner. Wondering if you guys had any other exhaust suggestions or suggestions in general. Planning on doing all installation myself other then tuning.
