Exhaust question

So I just purchased an Ansa Silverline catback exhaust on Ebay, and I LOVE it. Great sound, and I prefer quieter exhausts so it works really well for me. My question is if I do a Zetec swap, can the exhaust stay? Im not sure if the flex pipe would be different, I cant see why, but you gotta love how unnecessarily complicated things can get! Also, if this question has been answered before, I'm sorry, but I couldn't find it

Sounds good. I figured that would work, I was just curious to see if the bolt patterns were the same

Oh, I have a question. My wife and I are in a decent position financially, so I'm trying to decide if I should rebuild the SPI or go with everyone else and do the Zetec/Duratec swap. It seems as though if I dropped the same amount on rebuilding the SPI as I would on doing the swap I could get a decent engine out of it. I only have 55K on my car stock, so I'm in no hurry, but I would love to get some more power in this car. How much hp could I get out of this engine. Seeing as how the SPI comes stock with 110hp, and over the years it seems to lose a lot of that(referencing the dyno thread with ZX3_Chick's old focus that had a decent amount of mods yet only pushed 97hp, although it was an auto) I'm wondering if it's a lost cause. Thanks for tolerating the n00b questions, I appreciate it.

stock zx3 = 130hp to the crank... thats like 100-105 to the wheels depending of the weather conditions.

more aftermarket support for the zx3 when compared with the spi and responds better to mods. plus its not a time bomb...

Yeah, I guess I was figuring that if I swapped out the internals that it would no longer be a time bomb, so it was more of a question of HP. Maybe I'm wrong though

Yeah, sorry for my improper usage of the term, the valve seat is the ticking time bomb part everyone refers to. I was trying to generalize and say that I would swap out EVERYTHING, but I guess just the word internals to me means everything you cannot visibly see in the engine.
