K. Going to order these 94106's soon then. Thanks for the help everyone!

 

These will be a direct replacement correct?

 

yes sir. 2.5". just make sure the 02 sensor on each cat is welded AFTER the cat when installed. you will be good to go.

 

man...you got more advice and help than i did on my exhaust thread...

enjoy your new setup...

 

ask away partner

 

I actually just found this: http://www.sparktecmotorsports.com/h11455s.html

I'd rather go with this setup since I'd get LT headers...would I need a dyno tune with this? I know on my 07 mustang I need a tune with LT's...

 

haha if you have that cash go for it. A tune would prevent it from running lean. that would be a nice setup!

 

I'm just wondering how lean it would run and if it would throw a code...

 

come to think of it, i wouldnt run headers with a single pipe exhaust. keep the flow the same on each bank and not choke it down to the Y pipe. I know intakes cause the 3V motors to be lean, which is fixed by a custom tune.

 

Well crap...guess I'll just go with the new cats then and wait for a good LT with H-pipe setup. Thanks again guys!

don't wanna thread jack...

 

Ha it's fine sruiz2169 As far as I'm concerned I got the answers I needed

 

If you're gonna order those 94106's make sure you order them from Performance Peddler and use the code "clubgp". Much cheaper than Jegs, Summit, etc.

 

Which one of these 3? http://www.performancepeddler.com/se...=ALL&x=17&y=10

 

I just ordered the 94106 cats from Performance Peddler. Got them for less than a $100. Don't plan on installing them until after Christmas. If you get them and install them before then please post if you needed the O2 extensions.
