Hi guys - this is my FIRST post on this board since it's changed over to the 'normal' style board 
.
Anyhow, even before the change I wasn't around much, mainly because of the difficult reading style (click on each dang reply to read it). Now that it's a 'normal' style board, I hope to hang out here more often! At least during the summers when my Cougar is on the road.
I have yet to put a new sig together, so I'll describe the car so as to get the best possible advice from you guys - it's a 1992 Cougar XR7 with the 5.0HO motor, no mods done as of yet to it, but an Edelbrock headswap may be next springs project.
That said, what's the best diameter exhaust for this baby? I have a 2.25" custom piece made up to replace the original part at the front containing the catalytics, but it only reaches for about 4 feet behind the manifolds. From there it's a 2" system, correct?
What I want to do, is make a 2.5" TRUE dual exhaust system, but I'm worried about the existing power level of the engine. With a stock engine, is 2.5" exhaust overkill? But it should be perfect for an Edelbrock headed motor (even though it isn't in there as of now), right? Regardless, I'm making a DUAL EXHAUST system from at least the existing custom pipe and back, but wether I build it right up to the engine is my question, and of what diameter.
Sorry if it's hard to understand - newbies can be soooo frustrating, eh?
