I think the next thing I'm going to do to my car is add a set of SFC's, so i'm wondering if i need to do my exhaust first? I still have the crappy stock exhaust and will definetly upgrade it at some point but if i put SFC's on will i have just screwed myself?

 

I believe if you get the Spohn SFCs, they allow for the use of single and dual cat setups, so they should offer lots of clearance. What exhaust mods do you plan on doing? In all honesty, your car has lasted in excess of ten years without SFCs; I think it can last another few months.

 

I want to throw a hooker cat back, 3" catco cat and some hedman shorties on. I figure the headers wont be an issue, but Im wondering if the SFC's will get in the way of the cat back when i got to put a new one on. Also, where i can i buy a wonderbar from? anyone?!?!?

 

Yes, do the SFC's before exhaust. If you do it the other way around, the exhaust (or parts of it) will have to be dropped so the SFC's can be installed. Even if the SFC's were made for that exhaust, they should go in first. If you are worried about fitment after installation, then you need to ask the manufacturer. For the most part, you can make the exhaust fit after you do SFC's. What you dont want to do is install exhaust and then find out later when you do SFC's that the exhaust wont fit after the SFC's are installed.

You can find a wonderbar on Ebay. I saw 2 of them up for sale today.
