Differences in sound, performance? Pros and cons?
From what we've seen on the dyno, shorties are worthless on anything past a FoxBody. But with some states (cough...gay...California...gay...cough) you don't have a choice.
Kooks LTs and catted X we've seen 20whp gains with a tune change even on N/A cars. And the power under peak is just tremendous, not to mention the sound. Not terribly louder with the cats, but boy is the growl meaner.
1 vote for the DRs! Much more beneficial...If there is absolutely no benefit, then I'm using the money to get a set of DRs and wheels.
Unfortunately I did not find this out until after my short headers arrived and I went to install them...
The problem with any short tube header on a S197 Mustang is this...Your stock exhaust manifolds ARE short tube headers. Therefore, switching to another short header (even an equal length header) will do little to nothing compared to stock short tube headers.
[FONT=Arial, Helvetica, Geneva, Swiss, SunSans-Regular][/FONT][FONT=Arial, Helvetica, Geneva, Swiss, SunSans-Regular] Even the exhaust manifolds have a header like shape cast into them unlike older 4.6L manifolds which were essentially a tube with 4 tubes leading into one log. The ‘05 manifolds basically have a 4 into 1 header design. [/FONT]

Though I agree that the stock manifolds have a header type design they are NOT short tube headers.
Dude, I had my stock headers and my FRPP "shorty" headers on the bench side-by-side. With the exception of the rust vs SS, they are identical.
If it looks like a duck and walks like a duck...
