Exhaust and warranty?

[Pastor Robert]

I took my Pony in for an oil change the other day and while I was there I asked about dual exhasut. Much to my surprise they told me that nonthing was available for my car, though the salesman told me different when I got it. That's another lesson to NOT trust salesmen.

Anyway, I'm going to look into having it done locally. However, does anyone know if this will in fact void my warranty? Besides picking up a few horsepower and sounding good, I think the fuel mileage would be better. I'd really appreciate any input on this before I run out and do something I might regret.

Also, while I'm at it, does anyone else experience a situation where their V-6 runs better before it reaches operating temp? Mine will run like a scalded cat at any RPM before it reaches the normal operating temp, but after it's sluggish until it hits 2500 to 3000. I'd like to hear from anyone who has a simliar situation.

Thanks,

Pastor Robert
