That midpipe-only clip is enough for me to just go with that since we don't have any more exhaust options. Thanks for sharing!

Followup question since I can't remember and can't find anything here. Would a replacement of the midpipe keep the stock catalytic converters? I haven't crawled under the car to see exactly where the cats are placed.

It will remove the secondary cats.

Hadn't thought of that, could look really good. I'd go blue if it was me but black chrome would be great too.

Excellent exhaust clips, thanks to everyone posting!

I have a support ticket now with Lexus USA to find out of the Lexus Performance Exhaust is coming out for the IS 500 (and a date if it is known) or if it was listed by mistake. I will update if I ever hear back from them.

I checked this morning. I guess the bottom tips are a lot dirtier. Seems like about 75% of the exhaust gas seem to be coming out of the bottom section. So I will have to clean the bottom tip a lot more :/

As far as compared to stock, it's louder for sure. Inside the car it sounds real nice, not too loud (the Lexus is well insulated) and no drone at all at highway speeds. When I drive by walls or underpasses I floor it and it sounds amazing!!
Can you get rolling clips? I'm curious how it sounds under load.

I got the oval black gloss tips from GTHaus and they do look very nice. They’re also bigger than the stock tips. And you can’t really see their signature vertical bracing in the tips like the circular ones.

I did not. I don’t regret it. It’s quiet enough when cruising.

If I had to do it again I would have probably got the oval
