Need Help With Exhaust Tip

Hey all. Anyone know where I can get or have someone weld an additional exhaust tip? I currently have the Apexi N1, however it is coming up a little short and as a result it is leaving a permanent black mark on my bumper. I just need a tip (115mm in diameter to mate with the N1, and preferrable SS) about 1-2 inches long so I can have someone weld it so it will stretch out far enough so it doesn't burn my bumper. Any ideas?
