Catback but already have muffler help?

My car has 40 series mufflers well I just got my BBK X-Pipe O/R installed today but now its a little to raspy and now I want catback exhaust with 3" tubing, so problem is where do I get the tubing without having to buy new mufflers? I know I could go to an exhaust shop and have them bend new tubing and re-weld but is there a cheaper place to get tubing without new mufflers??

autozone sells 3" aluminum tubing. you could buy it, then take it to a shop and have them bend it to shape and install it yourself.

otherwise, check ebay/craigslist for a used catback.

You nitwit..... 3" catback? Have fun having no more low end torque due to an excessive lack of backpressure.

So... clarify this.
You want 3" cat-back pipes with the mufflers you have now? I highly doubt the inlet and outlets of your mufflers are 3"... so what are you going to do about that? Neck the tubing down on each side of the muffler?

O/R X's sound raspy... You're gonna have that.

This ^ no matter what muffler or size tubing it's going to be raspy compared to stock or an H pipe.

Ok I take that back, I think I am confused. This is what I got installed
BBK Off-Road X-Pipe (99-04 4.6L) 1669 - Free Shipping!

So it is 2.5" so what do I need to add for catback? or do i not add anything other than tips?? I also have a small leak in the weld to my muffler which is getting fixed tomorrow.

So if I have 2.5 tubing and 3" muffler inlet and outlet will I be losing back preassure? If I am not then will it be ok to 3" pipes from muffler on back and add 3" tips?
