Hooked up the old (Cherry Bombs) dual exhaust today to the newly built 360. The old exhaust on the orginal 318 sounded good for what it was. So I thought the 360 would sound as good or better for a temporary system but after hooking it up it does not sound as good as the 318. What gives? Does the extra horse power and compression need something different? Maybe it's the headers sounding different than the stock manifolds? I had plans to this Summer to run a larger pipe and perhaps Flowmasters but I don't know if I can wait.
