I've seen posts about less than desireable bends due to clearance and diameter issues.

Is this throughout the system or in certain spots? Reason is I'm researching different exhaust options and wanted to maximize my bang for the buck butt dyno result. Different systems replace different parts of the catback - some the entire (like Milltek), others the resonators (ECS) and others the mufflers (Tubi - as I understand it).

Thanks,

I don't know where you've seen anything about 'less than desirable bends', that simply isn't the case.

i've never looked at one out of the car before (only from below looking up). I'd like to get an overall idea of the similarities and differences. I appreciate it.

And no, I did not step on the pipes, Audi did it all by themselves.
