Do you think a set of 1 5/8 mid length Kooks headers with mandrel bent catted 2 ½’ into 3” single, back out to 2 ½” dual exhaust would be enough to support 9psi and 425 flywheel horsepower?
I could save myself about $200.00 and a big headache doing it this way instead of running true duals all the way back. The headers are already costing me a mint as it is, so if this set up will support my horsepower levels, I'll do it.

If you'll notice my signature....I don't have Mustang. It's for a Cougar, which running a single saves me a huge headache. The system will have 2-cats by the way, then Y-into a single 3", then back out to duals for tailpipes. I just wanted to make sure it would flow enough for my projected power levels?mustang70 said:Ok, I don't see how having to make a custom mid pipe with one cat is going to save you a headache. I would stick with the dual system myself.
Here a rough comparison....
Dual
Single

Ahhhh ok. I'll blame it on the recent surgery. I think it would be enough size for you. The F-bodies run 3" intermediat pipes with two cats and make some decetn horsepower. So I think it'll be fine for you. Are the dual tips just for comestics?
Pretty much. I guess it mostly for sound, although I would imaging it aids to flow and equalizes exhaust pulses much like an X-pipe does. I figured it would do, since like you said the GM's have been running it like that for years. I was just worried that it might choke things down a little on the top end.mustang70 said:Are the dual tips just for comestics?

With the F-bodies they recomend going with a one in one out set up. They said that doing the 180* turn to get to the passenger tailpipe wold restrict flow. But that's something you don't have to worry about.
