Oh i know but its all good! Thats what we club lexus owners do right?! Sharing is caring! I spent a total of around $600 do it. The only thing i would change is adding Vband clamps to everything. I did use mandrel 2.5" cut into sections to make it which is why it cost so much. I do hate crush bending with a passion so i opted to do it this way. It also pops really awesome at high rpm decel lol

Well thank you for your kind words, i can make a few of these custom again, anyone interested? It but basically take the X concept, cut it in the middle and make it merge into a long 3" pipe and split again into two after the muffler. I had talked to my buddy who is a flow dynamics engineer and he said with the pulsing it should help to pull gasses. I did notice much better response and power from it after i did this exhaust. Ill see about getting an acceleration vid up

Also interested to know about cabin drone. Have you got any acceleration videos yet? I did a similiar set-up on my SC400, getting rid of all of the stock exhaust from the cat's back, and replacing with dual pipes into an x-pipe then into two magnaflow mufflers (can't remember the p/n). It sounded pretty good but had some rasp to it. Does this setup create any rasp? Is there a benefit of the one single muffler in the middle over two at the normal position? Is your set up 2.5" piping all the way through?

Sounds nice. I think I'll probably go with this muffler for my build. With a V6 that's suppose to be the proper way to plumb it since the scavenging pulses work better off of a Y pipe. V8s I guess have more overlap and that's why they can benefit from duals with an X pipe.
