Doug Thorley Y-pipe on your FJ in California?

Anyone using a DT y-pipe and have issues with smog? I know they now include resonators that look like it could take the place of the secondary cat converters visually. I'd like to work on tucking the skids so I'd like to confirm there are any issues or just modify the OE y-pipe. Also, I haven't been to a smog test for a couple years. For our obd2, no more sniffer test correct? Only visual/electronic check?

Thanks!

I have a used set taking up space between my manifolds and muffler. Rattles a little bit like my last set did. Thinking about swapping to URD Y pipe and BA muffler/resonator to drown out the URD rasp. Would also open up area to install an Atlas...

@Iconic_ sell me all your DT y-pipez lol. I thought the rattling was pipes against your skid. What is touching this time? The slip fit? I'd like to get rid of my skid spacers (rci style) and cat protector tubes eventually.

G'Day JP,
Might be worth a chat with Keith at BAM, ... he knows heaps about FJ exhausts....
and local ( CA ) to you
There is also a bloke DU, now making skids from 4mm SS, that do away with the Cat protectors, using wings on the skid...
Designed to tuck up high and increase clearance... shipping would be a killer tho'.
Cheers
Baz

It was touching there when flexing offroad, but I cut that area back a bit and it doesn't hit anymore that I'm aware of. I can bop it with my hand and I can hear a rattle coming from inside the resonators, like little pieces of metal ringing around. I shipped my previous Y back to DT for replacement and the new one again, slightly rattles occasionally when shifting from low to high idle. Shipping to so-cal is $60 IIRC otherwise you could have it for cheap if you wanna try it out.

Re: Doug Thorley Y-pipe on your FJ in California?

@bazross Still planning to stick with aluminium skids for now. If it gets that mangled beyond repair, I can always switch back to steel but I like the weight shedding program. I don't hit rocks enough and when I do, it leaves cool marks

And thanks for the heads up about BAM. I don't need much special. Fairly happy with the AFE high tuck and just wanted a confirmation the smog law doesn't get me for swapping the y-pipe. After that, i can remove the clearance spacers and cat protectors which may give me 20mm clearance. But ricochet gas tank skid still hangs about where the transfer case member is so I don't know. Still some more planning and execution to go...

Got it. Well let me know if/when you decide to go with the URD/BA setup. I'll take your DT gladly. Just let me know final number to PayPal for the pipe and shipping when you're ready. Thanksssss!
