#717 installed. Unfortunately there is a defective resonator, whether it's coming from the test pipes or the 18 incher's I'll be finding out on Wednesday and getting in contact with Tony. Even though it is a major bummer, the sound is still out of this world, besides the extremely annoying bad resonator rattling. I haven't seen too many issues from bad parts coming from fast intentions so I would assume I am a very isolated incident, which is just my luck
. Regardless, the quality is absolutely top notch and I would still probably go with them if I had to do it again. Knowing Tony is a reputable guy I'm sure this isolated issue should get resolved.
