Looking for a full undertail exhaust system for an 07 s4rs. Any ideas?
Zard made a full system and Spark made a slip-on system. I can't really think of any others.
You could always go the custom route.
http://www.stradafab.net/ Randy used to be a sponsor here, but his level of work/product was more than most of our members were willing to spend, so he dropped his sponsorship. He's still a good guy, and an excellent craftsman.
Quad-D is an underslung look, but would give you the same look
