I recently (last night) bought a 2007 double cab TRD Tacoma that has what i believe to be a factory installed TRD Cat Back exhaust system. I do NOT like it. The truck is immaculate, purchased in Massachusetts. It has 43,000 miles. I am willing to trade with someone LOCALLY for their factory exhaust...with the stipulation that they help swap the exhausts out. We can do it in my garage. The exhaust has to be in great shape as this one is also. Any interest? Let me know.
