Has anyone on here positioned their three way catalyst that was not a direct fit model? I'm having trouble locating a direct fit model for a good price here. The only ones I've found are adjustable and need welding I think.

 

www.summitracing.com has direct fit cats, just look up the year and well im sure you know how to do it. i bought stuff just last week and finish up my manifold to cat y pipe during the weekend, and yes slipfit ones need to be welded i wouldnt trust clamping a cat
