Wimpy Pipe Update
Here's an update on my exhaust / side pipe situation.
As I wrote a couple of weeks ago, I cut out the glasspacks and inserted a pair of Moroso Spiral Mufflers.
Yesterday I had my new engine dynoed and after breakin and 24 or so passes with adjustments in timing, etc... we got the engine to produce 520 HP. We took the dyno headers off and mounted the headers and sidepipes that go with the car.
Wow, am I ever glad I did this. The engine made 520HP at 6,400 RPM with the dyno headers going through the dyno's outside muffler system. With the new pipes on it made 505HP at 6,300 RPM. Only a 15 HP loss!
And almost as important to me...the sound is awesome. Music!
This is a good way to go for those that have too restrictive exhaust systems and/or wimpy sound.
