| Dynomax turbo muffler with 2 1/4" pipes. One pipe is centered and the other is offset. These are a striaght through muffler known as a turbo muffler. They have a nice deep rich tone and zero backpressure. The Dynomax and Xlerator mufflers are our mufflers of choice. The Dynomax's are an aluminized muffler with crimped seams. They use fiberglass matting for the muffling material. They work for both turbo and non turbo cars alike. These mufflers will fit all z's from 70-89 except for the 74 260 Z. For that year of z, there isn't enough room for an oval muffler unless you let it hang down too low. That year needs a round muffler. The 79-89 zx's came with a round muffler, but these ovals will work just fine. They must be welded on. We recommend using a single turn down tip on the cars from 70-78. On the zx's with dual outlets we sell a twice pipe tip that fills the exhaust cutout on the body just fine. We have to special order these, please allow an extra 2-3 days for delivery.
