SFC's first, or Exhaust???
I bet this has been whipped around before, but I didnt see anything right away...SO, is it easier to do the SFC's first, then put on the Exhaust (Edelbrock TES, and 3 inch Cat) OR is it easier to do the Exhaust first, then put the SFC's on...I have the car up in the air for the next week, or so doing some suspension upgrades.....Thanks for any help on this subject....Tom

sfc first. its a lot easyer with the exhaust off. then build the pipes around the connectors, most sfc go over the exhaust, not under.

I agree. If you do the exhaust first, you may find the sfc's hit the exhaust, then you have to re-do the exhaust.
If you do the sfc's first, all you have to do after is build the exhaust around the sfc's

The TES duplicates the stock exhaust system EXACTLY, in terms of routing.
The inlet diameter of the cat is irrelevant.
If whatever SFCs you're talking about will fit stock exhaust, then they'll fit TES.
It shouldn't matter which you put on first. It's probably easier though, just to have working room, to put the SFCs on while the exhaust isn't there; like the other guys say.
