Recently got the Magnaflow Cat-Back exhaust and wanted to give a review. I have the base model so I don't have the fake exhaust sound pumped into the car, so from the factory the car is lexus quiet inside, and I just wanted a little more sounds. I ordered it from
Magnaflow Exhaust Solutions, they currently are running a 20% off sale so I was able to buy it for $959.14 with free shipping. I do want to mention that hottexhaust.com has very mixed reviews and their BBB rating is awful, but my order went through fine and I received it less than a week later.
As far as installation, I had a local muffler shop install it for $180. It was a little loud from inside but I thought it sounded pretty good, and the drone didn't bother me, but my daughter said it felt like her head was about to explode riding in the back
seat. I went back to the shop and mentioned I heard on the forums that exhaust tips helps with drone, but the guy said that was hard to believe and insisted on Vibrant Resonators on each side. After installing the resonators the overall sound got lower but the drone/reverberation was 10 times worse, felt like the pressure you feel on an airplane when you go up. Went back to the shop and insisted they try tips, he was adamant that you don't want to have exhaust tips fixed to your exhaust pipe and squeezed through and touching the bumper opening, so he suggested extending the pipes to almost to the end of the existing tips but not touching the tips or body of the car. Whatever, I just wanted to get rid of the drone so I agreed and I also asked to take the resonators back off. After, doing that it was night and day difference with the drone. If fact there is ZERO drone with the tips extended and overall it's way quieter - my daughter agrees. I actually wouldn't mind if it was a little louder.
From the outside it still sounds pretty good. I was worried an aftermarket exhaust for a 4 cyl would either be raspy or fart-can boy racer but it has a nice deep sound and it's not too loud, it's enough that people around you can hear and do a double take, but not annoying. Feels like driving a different car now. Highly recommended!
