Al,
It sure was a ton of work in a very short amount of time. I took about 2 weeks between work and familly time to plan out every thing I had to do. I made a check list and diagrams of everything I could think of. If it was not for that organization, it would have been impossible to pull off. The fact I was also in a very well equipped shop and had nice weather in the 70's the whole time too also helped alot. Charlie (the shop owner) is a great friend and a huge help. I talked with him again today and he already has the "Y" pipe done and has it plumbed into the existing DynoMax Ultra Flow muffler from the turbo motor. I wish I could hear what it sounds like. With open headers, it was just radical. I have never heard a motor roar like that except at a drag strip. Even prepared class cars at an auto cross don't have that deep of a growl.
The left side CAT location is the stock Celica position and the right side CAT is in the stock Supra position. I really didn't have any choice to move them as there is not enough room under the floor. Even in the proper CAT locations they are pretty close to being the lowest point on the car. To try and keep the smog nazi's happy, I will also wrap the pipes from the manifolds to the cats with the ThermoTec to help keep the exhaust hot and light the cats off faster. I tried to locate them closer, but it just would not fit. I hope the Lexus CATs are in good sape as they are better flowing than the CatCo ones I was going to use, they are basically free since they came with my motor, and they are shorter in length making the bends fit easier. The only bad side is if they are not working fine, it may be tough to fit CatCo's later due to the length.
