my x-pipe and mufflers scrape on everything. i have a catless x too. it doesnt harm it except scratch it a lil, i took it off and scraping as much as i do (pretty much everyday for over a year) has not harmed or ruined the integrity of either my x-pipe or mufflers. at all. scraping is part of having a lowered car, it doesnt hurt your car (especially since SLP is full SS)
