[DeTomaso] [SCPOCA] Breathing Better - Part 3 [5 Attachments]

[Tomas Gunnarsson]

John,

I predict a rather unpleasant sound from that mod. I've heard a car so modified and it's at the bottom of my sound list along with a car that had the muffler cans removed completely and had resonator tips only(!) attached to the pipes.

Use your higher college math and you can calculate the area of the inlet pipe and the combined area of the two outlets and you'll be shocked.
