do i have to take off the bumper since this is a base and these are base tails?

I went with custom magnaflow muffler with 4" magnaflow tips, but I went full catback.

hay boss, just wondering what the quad set-up is going to be? i'm in the same boat, i've got 07-08 type s rear cover waiting for a quad tip exhaust in my garage. i haven't had time to brainstorm possible custom set up. i'm looking for quad tip muffs on back not the whole piping.....i like my third stage as it is but MUST have quads!!! let me know what you come up w/ or maybe you're waiting for ATLP v2 quads??
