ok so i have the hks exhaust on my car and how my drive way is is that im always scraping it right were it flexes behind the front weels were its like the thin metal weaving. My question is how can i protect this from shredding the metal?

 

Only thing I can think of is to weld on some bump stops just in front of and behind the flex portion so that they are no longer the lowest part under the car. Either that or replace the Y-pipe with one that does not have flex pipes.
