I picked up this stretched slic from a buddy yesterday. He is upgrading to a fmic. This was in his car when he bought it and was installed by quad air around 2002. The car came from Illinois. It is about 15" long vs. the stock measuring about 10". The inlet and outlet both measure 2 1/2". There are no tags anywhere on it and I was wondering if anyone could idenitify it. We were thinking it was made by precision.
