So I called them and they don't have direct fit for 15 model yet but they said I could weld the universal one but idk how I feel about welding...

 

But they have one for 2014? Aren't they the same...

 

That's what I don't know bro....I was assuming sooo....just would suck to order something then be like damn.....

 

I converted to full Joe-z cat back on my awd. The mid-pipe addition on the new kit in comparison from my old axel back setup is subtle. Sound is there. Start up sounds sick. Idle there is a nice lub dub from the v6. WOT is effin amazing. Yet, I have a tekdata intake so it's loud. Throttle response is a lot better and acceleration from a dig is a little better

 

Those are universal cats.
You have to cut your OEM cat and weld the HFC on.
Just pick the correct piping size.
You can find a set of 200 cell cats and weld it on if you want something loud.

So tired of my F Sport exhaust, I've had it since January and upset that I spent 1300 and yes it does sound just a tad bit deeper then stock but no significant change. On my 2009 I had the 2nd gen exhaust and it sounded awesome, this one not so much. I just went to Midas to remover my resonator but he said that Lexus already has their own for performance. Should I purchase an Invidia Midpipe or what setup should I use? For 1300 you'd think there would be some sound but not on this...

 

Yoooo im gonna add a midpipe and high flow cat if I don't end up selling mine, and im gonna go with the Ark full exhaust if I do sell it, however ive had it for two weeks and it is starting to sound better and better.
