Mac has a shorty mid pipe that is used with long tubes. I think you are assuming I was talking about a normal length pro chamber. Is that correct?. That would be impossible unless you had a torch, which I do not.
Now I just need to decide weather I want to stick with the trusty bbk o/r H or switch to an o/r X. Back to the exhaust compilation thread!
Yeah it sucks, a lot of exhaust components are like that. I've only heard a H pipe on a 4v car once, and do NOT like the sound at all. It was a o/r H pipe with a Bassani catback.
