I am selling a Superflow Muffler that was sent new to me by Vintage Speed to take care of a leak problem on my existing Vintage system. I installed it and ran it for 10 mins on jackstands , but that did not fix the problem. Seems to be my j pipes and they have been good about working with me. I reinstalled my old system for now. Technically the Muffler would be considered used. I have the original packing that includes flanges for heat or no heat applications as well as unused short headers. They sell the muffler on eBay at the lowest price of $461 plus $90 shipping from Taiwan. (PN 155-204-052 SF) for Replica 356 up to 150 HP. I am selling for $300. Shipping would be approx $65 to the East Coast (N.C. As an example). You would need J pipes for no heater apps - $129 from VS on eBay plus a Gasket set - $26. The pics include the pipe location as seen using my existing system on my JPS Coupe. Thanks for looking

The Sidewinder sounds deeper yet louder. With the Vintage Speed Muffler, it doesn’t breathe as good but it looks great and sounds more like a Porsche. My muffler is starting to get that bronze tint that looks cool too. I just received payment for the muffler, so it is sold. Thanks for the interest though.

How is the tone? I have a hideaway system and have been thinking about going back to the dual tip look. Looking/Interested. 


You could always have a dual tip extension built off the muffler. I'm pretty sure there's 1 or 2 guys here with dual tips off of a Sidewinder muffler. Can you post a pic of the exhaust?
