Hey all. I have a 1989 LX 5.0 that's pretty stock except for exhaust gears and a short throw shifter. I'd like it to get some different mufflers and also look into headers. the previous owner had done a cat delete then added flowmaster super 44's and 2.5in stainless steel pipes from the down pipe back with polished tips. I looked around some stores and considered SLP loudmouth, or super 10's. For headers either BBK or Pypes. Also not 100% sure what difference it would make between shorty headers (equal and unequal length) or longs tubes. Any suggestions, or information in general would be much appreciated!
