I know that it is a bit more difficult to get a good tone out of a straight six than a V-six, and I am willing to compromise a bit, but I just dont want a setup that comes out "ricey".

1. I believe you can use the same midpipe after the swap. Not 100% sure, but it's very likely.
2. I'm also pretty sure that your 'cat back portion' is the same for both the n/a and the TT. Regardless, please note that the oem TT exhaust works just fine for stock boost levels with the oem twins, as well as BPU.
   In other words, the oem TT exhaust is not a restriction, and you will get no horsepower increase using an aftermarket exhaust.
3. Good tone from a v-six? Gosh. I've heard of folks talking about "good tone" from a big-block V8, but a v-6? Weird...
   Fwiw, to me, any v6 sounds noticeably worse than any I-6 (especially a 2jz).
4. When you're pushing a lot of horsepower and winning races, no one really cares what your car sounds like...although with all the extra exhaust generated with race fuel and big boost, it can't help but sound good too.
   About the only way to get a "ricey" sound, imho, is to put an open (i.e. loud) exhaust on any low-horsepower n/a (that includes low-horsepower V8s). *shrug*
5. To me, the only reason to put an aftermarket exhaust on a stock TT or BPU Supra is for looks. If that's your deal, I understand completely...don't want to be parked next to the guy at the car meet when you've got a relatively small tailpipe. Chicks dig big tailpipes (so I hear). However, if that's all you're looking for, just take a short 4" pipe and/or transition, cut it on an angle, get it polished/chromed, and get it welded onto your oem exhaust. You can even get tips pre-chromed. Either way, it'll be a lot cheaper.
