I have a set of the hard to find Hooper wrinkle pipes for the Thundercat 900, 1000 or big bores up to 1108cc. I bought these off of a guy who was running them on his Hooper 1050. He tried several other sets of pipes on his motor and he said that the Hooper wrinkle pipes were always faster. I've seen dyno sheets on the wrinkle pipes and they makre more torque than other pipes at lower rpms and hold it through the rpm range. These pipes are good because they don't like too much timing or compression and they will make good power. Run them through a 98 Thundercat can and spin them anywhere from 8800-9000 rpms. RPM range may differ depending on what you have done to your motor or if you use the 800/900 can. These pipes are for the 95-98 chassis but can be cut and fit for the late model ZRT chassis. They have light surface rust towards the head pipe and a couple of small dings in them but nothing to effect performance. Why am I selling these? Because I am buying a set of the wrinkle pipes that are already cut and fit to my 2000 chassis. $350 shipped or best offer. If you live in Michigan, northern Indiana or Ohio I can deliver.
