i was wondering where i can buy a good testpipe that will match up with my rb header and apexi gt catback. i looked at corksport and they had one but i dont want to spent 150 bucks for it and plus its a presilencer. right now i have a testpipe on there that a muffler shop made me and the flanges dont match up right and i thought if i put the red rtv sealant on the gaskets it would be fine and i was wrong so now i am going on my 4th gasket this month. i dont want to go back to the shop to have them redo it cause then ill just end up getting another piece of crap

 

your local exhaust shop, me and a friend went and had one made a few weeks ago $15
edit NM... looks like your local shop sucks

 

Nothing aftermarket will quite fit up. Most test pipes are supposed to replace the stock cats. The RB header ends a few inches short of where the stock cat is. So unless you want to go to shop, the only option is their presilencer.

Or weld one yourself (XR-1 from Borla).

the problem with that one is that it says its 2 1/4 when i need 2.5 piping

 

I actually used to make and sell them on ebay for the N/A about 5 years ago. I remember seeing one at my parents house when I went to pick some up my GTUs tranny and TII rear end out of their basement. (I still have about 15-20 bins of FC goodness at their house!) It's brand new and even has the split air pipe inlet on it. You interested? Does not come with gaskets or bolts. PM me.

I will check the pipe diameter on Monday.
