I have a '97 Vougar with a 4.6 V8. I had the Thrush welded mufflers on it. I than last fall had the third cat removed and had true duals put on. The Thrush welded mufflers sounded like crap after the cat delete so I put Magnaflow's on.

I could be wrong but I have a feeling with the Thrush welded muffler your Sportage will sound like every teenagers Honda.
