exhaust options

[jsoutherland16 at comcast.net (Jeff Southerland)]

My advice is keep the stock manifold and DP. My experience with headers is
if it's not a 4-2-1 header, your gains are minimal-read not worth the
trouble- over the stock manifold. Some say even the 4-2-1 header does not
provide a large gain with stock bore, street driven motors. Most of the data
I've seen shows no real gains low in the rev range, where you need it the
most on the street. If the unknown header is 4-1, you can also have fitment
problems and flexing that leads to breakage. The noise levels -at the
engine- are slightly higher with headers, and even the best headers can have
problems on a daily driven car. I will never run headers on another DD. The
gains on the street did not impress me enough to justify the headache.
Remember this is all my opinion now.   Jeff
