Description Note: This product is to suit 01-07 WRX/STI with the 'short' OEM downpipe or with an aftermarket downpipe (cat-back is 100mm longer than Tomei 440006). Tomei has really done it this time. Notice a lack of a certain word in the title of this product? The missing word is tip. That word is missing because this is an entire Titanium exhaust at a very affordable price. Tomei starts with the very best in raw materials and takes it to the next level. This is exhaust is about one thing and one thing only; performance. They have started by stripping the weight down to what feels like nothing compared to the stock exhaust. They did this by using titanium over steel and making the exhaust as straight as possible. Less bends means less materials used. They even went so far as to think about the extra weight regular style flanges add, so they went ahead and went with a weight saving spring and clamp setup. So not only do you get the performance you expect from a Tomei product, you get the bragging rights too.
