BTW, I had my cats removed at the same time as combfilter. It didn't make a noticeable difference in sound. When I stood behind combfilter's car, and he free revved it in neutral, it did have a slight rasp at high RPMs, but the stock exhaust may do the same for all I know. It sounds exactly the same inside the car to me.

nabisco did you notice any gains? You didn't happen to have a dyno from before did you? It's too freaking wet here for me to get on it and see if i can tell anything.
Like gernby said there was no change in sound which is a good thing for me. I knkow the new mufflers will change the sound , but from reading GNN's reviews should be a good thing. If i remove my resonator later, I am going to do the same as gernby said. do an x pipe then straight back.

After getting my cats removed, and not noticing a change in sound, I've decided to go with the HKS cat-back exhaust (non-Lexus) instead of the custom Magnaflow setup. I'm sure the Magnaflows would sound better, but I'm currently leaning more toward power and weight benefit.
Combfilter has already purchased his Magnaflow parts, so i'm trying to convince him to sell the parts and buy the HKS exhaust. Earlier in the thread, he seemed to have the same views about sound / performance that I have.

What did you mean when you said "I LIKE!"? Were you joking?

The picture above still has the resonator! I was talking about my application when I was asked about it! Two completely different things.
When I said I like it, I was saying that I like his setup.
You can PM me if you have more questions.

Man ya'll left me out of the cat removal damnit!!! lol so gernby HKS for sho? I'm waiting for that other guy to post video of it on his 350 b4 purchasing.. So that shop had no reservations about removing them?

I've already order the HKS, and it is supposed to be shipping on Monday from CA. If I get it on Wednesday, I will retune my Piggy-Back ECU and dyno it on Friday. I doubt it will get here that quick, but one can hope. I will take videos right away though.
The shop didn't even mention the legality issue, but surprisingly, they did say that they are legally required to keep our cats for 15 days before they can give them back to us. I thought that was really weird, but I do want my stock cats back. I plan to reinstall them before selling my car.
I didn't get an opportunity to take any pictures of my exhuast when it was up on the rack, so I took a couple at home. After seeing combfilter's I asked that the guy cut the cats further back, since there was an obvious change in outer diameter for about 2" (where the yellow circle is). I don't know if the inner diameter is different, but the change in outer diameter is evident in the pic that combfilter posted.
BTW, does anyone know where I can purchase OEM looking heat shields (circled in red) for the exhaust pipes to hide the new pipes and welds?
