why do people keep typing Yvets its vyets >_<' rofl anyway the discription u made sounds like how my exhaust is. :o my exhaust helped, i got at least a 0.4 second off my time... unless my driving just got beter, i cant notice power diffrence but :P i rekon it helps, caus as axel backs on most cars only consist of a cannon + abitta pipe. however the trd axel is a long pipe + barrel + abit more pipe. compared to other axelback systems ours is way longer. or maybe its just my car stupid celicas. die die die!
