nice. i made my muffler from a dead bit clone motor. i superglued a cut piece of antenna at the end and i soldered 2 staples to the can and used a washer to press them snugly under the center rear bumper screw. since my skyline is lowered and i had it sticking out from an angle the thing scraped like half of the time lol especially under heavy cornering. it never broke off yet tho but since you dont use ur civic to race scraping shouldnt be a problem
