Off the shelf Exhaust kits - Feedback wanted

[*rayman*]

I'm considering ordering an off the shelf exhaust kit for my 68 BB Camaro.

Looking at a few different brands, like flowmaster, and Pypes. Seems to be a few different outlets to order these from and not much price variation between them.

To get a custom system put under here i'm looking at the following prices approx:
- 2.5" mild steel - $1000
- 3" mild steel - $1400
- 3"stainless - $1800

The prices are pretty ordinary, and i'm not 100% sold on the quality of them. It's a bit hit an miss, i've seen some great jobs come out of the custom shops here, and some really bad ones.

To order a system from the U.S, i can get 2.5" systems from about $400 up:

3" stainless from about $650 up

. Factor in $400 frieght (has to be fedex, or UPS or something, as USPS surface-ship will take 3 months to get here) and i'm still out in front.

My question is, who has used these systems?
Do they fit well?
Flow well?
What brand should i get?

The other benefit by buying an off the shelf system is i dont need to leave the car in a shop, and potentially get scratched up etc. It's only just come home from the paint shop, and so far i havent damaged it at all during assembly.

Thanks in advance for the feedback guys.
