Hey guys! I installed an F-Sport Exhaust on my car a couple weeks ago and I am experiencing some issues. Once the exhaust heats up, I am hearing rattling. It was installed correctly by a professional. Has anyone else experienced this or any tips/opinions? Thank you Lexus family!

Are you sure the rattling sound is coming from the exhaust?
Is it during idle, or while driving?

I am sure it's coming from the exhaust since I've experienced it many times before with multiple cars. It usually rattles if i go over any minor bump in the road. By minor, I mean everything. It's a real bummer and irritates me like crazy!

It'll be a good idea to go back to the shop that installed your exhaust and show them the problems. They should be able to figure it out and fix the problem for free, since it's only been a few weeks.

Yeah, that's what I plan on doing. I was just trying to see if anyone else has experienced these issues with the F-Sport Exhaust. If it is a defected product, hopefully they can replace it.

just put one on this weekend. so far 2 days and hear no rattle going over anything.
its only 2 spring bolts each side. cant really mess up.
maybe missing a rubber hanger?

I have tanabe and it rattles as well.....same design as f sport so probably a similar problem.

I sure hope so. The F-Sport exhaust isn't cheap..
I had mine for 6 months, and it worked perfectly with no issues at all.

No rattles from my F-Sport Exhaust so far. I've read in other threads that the heat shielding under the car can be the source of the rattling.

possible piece of the metal flange under the car is hitting the exhaust or just became loose. Either that or gaskets in my experience.

UPDATE:
It turned out to be the hangars which are attached to the car tapping against the muffler.

SOLUTION: I had them shortened.
