I had the extended version on my GT because I had a body kit. I tell you hwut, that was money well spent. I doubt it had any performance gains but it was lighter than stock and sounded really good without the rasp and rice. I traded in the car that had the exhaust back in March but for the 9 years that I drove with the exhaust it still sounds good since day one. If I still had that car I would part out the exhaust for you. Good luck on finding one. Also, if memory serves me right, I believe the TRD USA product line up for the Celica are mostly rebadged parts. Like how the TRD lowering kit is made by Eibach, I think Magnaflow makes the TRD version as well. I've read that they both sound similarly the same.
