Description: Twice Pipes were the first successful aftermarket exhaust system for the 240Z. It's designed with twin pipes (from the head pipe back) that terminate with two glass-pack mufflers, and chrome tips. The kit requires no welding, and includes all parts necessary for installation. If you're looking for more power, or doing an original "performance restoration", this is the system you want. If you are not familiar with a "glass-pack" muffler, the performance "staple" of the 70's, they are very free flowing, and as such will significantly increase sound levels. Please keep this in mind when choosing the best system for your Z. Give us a call with any questions.
Image Note: The system for use with our headers is shown here. The system "for stock exhaust" includes a new headpipe to attach to the stock exhaust manifold.
Special Note: For Federal emissions models only. This system can be used on 280Z off road vehicles where the catalytic converter will no longer be required.
Model Note: This twice-pipe system was designed for Coupes. It can be fitted to a 2+2, but would require extra piping to be purchased at an experienced muffler shop to lengthen the system enough, and installed in the proper place, for the longer 2+2 model.
