$250 for exhaust and points?

[NO_H2O]

What kind of exheaust are they going to install?
More than likley it is an Empi or something like that. You can pike up a single quiet pack with the cheap black paint that won't last a week for $50 and a set of points and condenser is like $5.
I would get a quality ceramic coated or stainless exhaust for $200 and spend the other $50 or a compufire. Then bust out the screwdriver and the 13mm wrench and do it myself.
