Where can I get an aftermarket downpipe for my 93ssei? Is there is someone who sells them with the Magnafolw cat? Thanks.

There is no aftermarket DP for the S1 L67, and you're a long way from outflowing it.

Do the cat seperately.

Ok cool thanks Will. One other thing is that my cat is already a small style aftermarket cat. I am not sure what brand probabally some cheapie, but would it even make a difference to do the Magnaflow? Or would the cat that is on it be fine? The only reason I am asking is because my downpipe is at an incorrect angle and everytime the motor torque'* the tops of the flanges on the DP and the EM meet and the bottom opens up. I have had this leak since I bought the car. I tried a new factory doughtnut gasket on it and it still hits. Therefore I figured since I need the DP cut and rewelded why not just put in a new one. Maybe someone has a different take on this?

I'm not sure about your aftermarket, but I can tell you that changing over to the Magnaflow made my car feel like a whole new beast. Were you planning on doing any intake mods to assist with your outflow?

As far as porting the lower and the heads probabally not. I was planning to do them when I did the gaskets, but my brother came up from Texas and with him doing the job I didn't have any time to port anything. I just want to fix the exhaust leak and figured I would use new stuff, but if I can fix it with the old stuff then cool. I just am not sure if theres a difference between the stock aftermarket cats and a Magnaflow.
