Purple,
Thanks, you're car looks just like mine.
Two more questions if you don't mind.
If you change the pully size on the supercharger, do you have to change the belt, or is there a tensioner that takes up the slack. If you have to change the belt, how do you know what size to buy, since it will no longer be the stock size?
The catalytic converter that you recommended - is that the one installed on your car? If so, are there no issues with codes?

I suggest a pulley size no smaller then 3.5" With that you do not need to change the belt size. If you went smaller then a 3.4" you would need to change it. Stock should be a 6 rib 725, you can go smaller if you want but it'* not needed. For that you can install a GB6-715

I'm running a 3.5 pulley and a Gatorback belt. No problems here.
The cat I mentioned is the one I'm running on my car. I have a 3" down pipe to the cat, no resonator, 3" to a Y pipe, and then split the exhaust out to Magnaflow 14324 and kept the stock tips. I went to this cat because it has no history of throwing codes out.

I'll answer both questions here.
No need to change the down pipe if changing the cat. There is a flange between the DP and the cat. Cut the pipe between that flange and the cat and weld new cat in. Unless you want a larger DP, the inside of a stock DP is about 2", can't remember exactly. I could messure it, I have one in the garage.
As for the over sized tensioner. This is fine with a stock belt size down to a 3.4" pulley. But no smaller. Here is what you get with a stock belt and a over sized tensioner with a 3.3" pulley
This is a stock belt with stock tensioner
The problem here is no belt tension so it slips.

Grape - Oops!, I mean Purple,
I don't want to beat this topic to death, but..........
What would the benefits be for the following scenarios:
Replacing my stock CAT with a Goerlich 608227 in the same size as the stock one.
Replacing my stock CAT with a 3" DP and 3" Goerlich cat and stock exhaust.
Replacing the entire exhause like you have done.
What are the benefits in MPG? In performance?
I appreciate your patience with me on this.
Money is tight, but I don't want to spend the outrageous price for an OEM converter if I can buy an aftermarket cheaper that provides better flow also. Also, what is the life expectancy of the aftermarket converter.
Thanks for all of the info. I greatly appreciate your advice.

I was looking at your album and the exhaust work is incredible. Nice stuff.
I'd like to replicate it on mine. I'd really like to find someone who works with Stainless, but nothing yet.
