On a nearby thread, csobel said that APR doesn't make DP/CATs for tip allroads, and that Milltek is the only choice, for a lot of money. Secondly, that a tech he knows has said that there have been lots of problems with Milltek DPs.

So, to get a high-flow exhaust, it seems that the options are:

1. Piggies, I've only heard of Vast or DIY. Then plus cat-back

2. Milltek DP/CATs for lots of $$$, plus cat-back

3. APR 6-spd DPs, modified for tip, then attached to a cat-back.

If any of you has come up with a better, even ultimate way of getting more power and better (but still classy) sound on an AR, please let me, and the rest of us know.

thanks,
