Top end is much better, but bottom is noticably worse, do you guys get that with straight throughs or does the pipe give that bit of back pressure that seems necessary for low torque?

You're confusing your exhausts mate, it's only NA engines that need backpressure.

Well thats what I thought - until my exhaust fell off. As said it's really noticeably worse bottom end BUT without restriction top end is better, so I'm thinking they do need some back pressure for low end.

It's odd though as I drove the Golf for a short while with no exhaust and there wasn't really any difference, wasnt even noisier, just whistled more, possibly to do with it being VNT though.
