Dump Pipes without a cat in the vertical ??

[parso_rex]

Does anyone know if there actually are any available for the 2.5 GTs. I'm thinking space may be a bit of a problem. The ideal position is in the horizontal for spool reasons but for legalities this isn't done. Still I'd be interested to see if anyone does it as an option these days. Hitech don't, Phats nice one doesn't & Carline (Think MRT) will but indicate the size and location of the cat may be an issue.

Thoughts ?
