I was looking to install XERD headers into my GS300, but I've heard from a few people that they are very loud and obnoxious. Has anyone used them? Please share your experience here, if you have them on your car.

I'm also looking for suggestions other than XERD for quiet headers. I will also be installing a Borla Exhaust system, and I want to find headers that have good performance but are not super loud. Please post any suggestions here.

Thanks!!
