My buddy can do a complete custom exaust for me. I've already modified the airbox to breathe much better. (weber will have to wait) The cat was gutted when I got the car.

 

So do I want to go two inch pipe fom the gutted cat, or lose the cat entirely?

 

I can't think of any reason to keep it.

It steers ok now! (warped rotor and E-brake cable too tight-duh!)

Buddy does exhuast? Throw the whole system away and have him rage it! Heads to tail pipe; straight custom all the way. Have him do a Y pipe setup so you promote scavaging. With the boxer 4cyl you definatly want the Y pipe or performance will suffer. See what he thinks about an X pipe even; have yet to see a Subaru with one of them!

ditch the gutted cat, it's still too restrictive.

i am getting a custom made pipe for my turbo wagon ,[the first cat big one] 2 inch pipe all the way to the turbo muffler

I have a y-pipe to straight pipe all teh way back to a big muffler with a huge tailpipe. It sounds really good at an idle, but is way loud when the motor rev's and then it has a backfire when shifting or letting off the gas (which I hate). Sometimes I wish for the quiet stock stuff back, but it does give a little more power with this set-up.......

I have been wondering if I should goto a custom pipe once my cat pluggs up, but I wouldn't want to go so radical that it changes the power curve, or that I can't keep it with-in adjustment of my stock carb ... maybe I should just goto a custom pipe and weber carb at the same time ... does anyone make after-market pipes with close enough flow rates to still get full adjustment with the stock carb?

Can you believe it? I don't know what you mean by a "Y pipe setup so you promote scavanging." When you say performance will suffer without it, do mean as opposed trying to run true dual? (which I have heard over and over is a very bad, non functional idea on these motors, THATS not the plan) I thought it WAS a Y pipe setup, just that the "Y" terminates in that stupid cat. Which I want to get rid of.

 

 

And to further demonstrate my ignorance, what do you mean by an "X pipe"? Is that a cross over?
