Who manufactures the mufflers FI uses? I know they use another company's mufflers, I just cannot remember who said company is lol. Anyone know?

Long story short, I bottomed out in Fort Worth and it ruined my resonators and my muffler. I have a terrible rasp or vibration noise (not from test pipes.)


Thanks!

 

I "think" that it's a Magnaflow muffler........

 

I wanna say they make the mufflers and magnaflow makes the resonators

 

I think the mufflers might be Sebring Tuning.

They for sure make the sedan mufflers.

 

What type of noise does it make? Mine bottomed out too but I cannot figure out what is wrong with it.

I get this high pitched noise at 3k rpm when car is cooler, and then it somewhat goes away after 5-10 min of driving

 

It was a terrible vibration noise that could be felt at 1,500 and 2,200 rpms. Exhaust shop couldn't figure it out and took it to a buddy of Mine who is a tech at a local Indy shop. He said I think it's your muffler. Took the aftermarket exhaust off and but the factory cat back on. The vibration is gone so looks like when I bottomed out I took out one side of the resonators and the muffler or x pipe.
