Apologies if this has been covered but I couldn't find anything searching. The previous owner installed an HKS downpipe on my 9. My test pipe doesn't fit perfectly (hard to get a good deal though I can get one). And my cat will only fit crooked, which several inspectors have flagged when I go to smog. I just tell them it's normal. Anyone else have these issues? Any recommendations on a replacement downpipe? Was looking at the RRE but I'm not sure if they still make them. And I know people like the Perrin but it's discontinued.

Thanks!
