No borla, sound like a$$.

You also have to think how much you drive the car, i.e how long do you drive to work and such.  Most exhaust systems rot from the inside out.  The cat's change the exhaust mixture to water and a less lethal hydrocarbon.  Have you ever noticed when a crusizer pulls away all the water that pours out of the exhast system?  That is what will rot a aluminumized exhaust system.  If the car gets up to operating temp and the exhaust does to a aluminumized system will last just as long as a stainless system.  If you do 10 mins here,  5 mins there. it might be worth the extra money for the SS just so you don't have to worry about it in a year or two.

I live in the NE not to far from Dan02GT.  Winters are brutal on cars but the short trips will ruin an exhaust system very quickly, the salt doesn't help either. The aluminunized coating is only on the outside of the mild steel pipe protecting the outside, it is to difficult if not impossible to coat the inside of the system.

That would be my 2 cents!

I agree with your logic on alum. vs Stainless, but the Aluminizing process takes place BEFORE a pipe is made a pipe. So it is  aluminized inside and out
