Pacesetters come with their own y-pipe. That Catco setup is just the y-pipe with a converter. If you got the headers, you won't need the Catco setup.If you were wanting a hi-flo cat, you would need to get one, as it isn't included with the headers.

 

Thats what i thought. I'll just replace my Cat with a Highflow one. I'll search around and see what everyone likes for highflow cats. Thanks for walking me thru this guys.

 

does the magnaflow cataylac converter change the cars sound r give it horsepower

 

minor effects on both over stock.

 

Well i got my codes checked and it thru out a PO420 for an insufficiant Cat (whick is exactly what i thought). While the car was on the lift I wanted to check everything out and it turns out my muffler is starting to rust out so i'm thinking about picking up a Flowmaster American Thunder Muffler (80's Series) along with a MagnaFlow Cat.

Would i see a much gain in performance by going with new piping from the cat back? I've found the FlowMaster muffler for $107 and can't understand why the whole FlowMaster 80 Catback setup is ~$400. Will the 2.5" piping offer anything more than my stock 2.25"? If so is there anywhere you can find just piping? I have no problem accessing a welder so thats not a deciding factor.

 

you wont see too many gains.However the catback does greatly affect your sound, more so than just a muffler will.

 

Hmm that makes it a hard decision. I don't think that it's worth $300 to me right now for a different sound, especially a V6. I guess i have something to think about. Might just do the Cat for now until I become more decisive.

 

most catbacks also come with dual chrome tips, which the stock v6 exhaust didnt have. just another visual incentive if it helps sway u. im personally a fan of a catback rather than weld in mufflers for late model cars

 

I have dual chrome tips now. I'm not sure they are worth that much to me.
