Ford racing exhaust

[GERMANORACING]

Hi can anyone tell me if there is any difference between the Ford GT long tube headers (#9430GT) with Ford GT performance muffler (#5230GT) VS Ford GT rear exit headers complete kit (#9430GTX).
Any performance difference and what about sound , which one in your opinion sounds the best.

Thanks

I have the borla exhaust and the ford racing long tube headers. I also took out the cats. In my opinion, the sound is an orgasm for my ears.:cheers
