Hey man. I'll save you some time. That was my main goal on my solara, dual exhaust. I searched all over and all i got was NO. I called a well known performance shop in new york and they basically said they would do it, but it'd be over $800 for oval pipe, plus if i lowered the car i run the risk of the exhaust scaping. See there is no exhaust channel for the second piping on the drivers side, so it would hang low. The other problem was that in order to keep the mufflers symetrical, you'd have to move the stock muffler over a bit. I spoke with "Mr. B" of teamsc3.com and he has dual exhaust. He ran into a lot of problems when he tried to put on the TRD body kit. Dual exhaust, from that cat back, (which i assume is what you are talking about) is impractical and too expensive. Not for our cars
