thats cool i really appreciate it that you were able to measure your catalytic. Now i can breathe better. I just ordered the gsr high flow cat last night at ebay.


so the ls has 16 inches long catalytic converter while the gsr"s from years 94 to 97 have 18 inch long catalytic converters. Meaning there is 2 inch difference between the 2 catalytics. Now it makes sense. Thanks for all the response.

all i can do now is wait for the high flow cat.
