Mike,
I installed the dual SS sport system from rimmer. I also have the 4-2-1
manifold. Yes, it does begin to glow quite nicely but I wrapped mine soon
after I got it. I have not had any problems with the manifold or any
problems connected to it, before or after I wrapped it up.
The SS sport has a real nice note to it, I had the monza prior to it. I
really like the noise level, as do the neighbours....
