92 xcab 22-re

22re exhaust system went so I bought pacesetter headers (which are much better quality than people say I've seen in person all three main brands and for the price pacesetter makes a good product), a high flow magnaflow cat and welded my brand new welded thrust muffler right to the catalytic converter is that going to be an issue. There is only 6 in. Of pipe any way. Any help would be great. Thanks
