So, Ive got the itch and only wanna scratch it once lol. Sound aside, is there a benefit to a full 1500+ dollar catback vs a 300 muffler removal? Which mufflers are people removing for the muffler removal / no drone / max performance? I have really found a good write up or legit dynos for the removal mod alone. I been eyeing the JUN BL GT? catback, which he claims +39HP, but +39HP even to the crank seems...... EXTREMELY generous. I don't even notice what they did other than change mufflers and polished the pipe(lol). Nobody seems to be oversizing the pipe at all. So, Im trying to hash out once and for all, price to performance, does a full catback deliver 1500-2k dollar results for the Kia Stinger. Posting in a few different areas to maximize input.
