I strongly suggest you don't weld the muffler or cat on.
Get the pipes widened for slip fit. Then you use good clamps. Slip the cat, test pipe or muffler into the exhaust pipe and tighten up the clamps.
thats the way L&R does them on thier $1500 304 stainless systems. This way you can replace a component without welding. Or fit your cat in place for aircare and take it out for runs at the track with leaded race gas.
and no, they do no leak. There really is no downside.
also, don't bother with a cat back. The downpipe is probably the worst part on the factory system. get/build a full turbo back.
And yes a 3" pressbent will be fine, as even a 2.5" system is good for around 400 whp.
