MSRP is $520.. So not as bad as it could be. I'll be sure to post noise and smell notes.
I'm wrong, this is as big as a single stock catalytic converter.
I have some spare pipe. I'll need to get a flex pipe connector and a 3.5'' ID-ID connector. I'll weld this cat to the stock (and cut off) flange I'll remove.

Not yet though last night I had time to get measurements and pics of the stock exhaust piping before the muffler. I'll be looking for flex joints and piping now.
It was more important to get my hornsx6 working.
Hard to get a picture of but this is what I have to work with.
I'll probably cut it out just before the muffler, enough to get a slip joint on. Then I'll cut off the flex joint and replace with the cat and a much smaller flex joint.
Stock flex joint is 10 inches, new cat is 7.5 inches.

I have misc exhaust parts and connectors on order to finish the cat install. I decided I'm not using a flex join. There isn't any room. Poking about the stock exhaust, the hangers offer plenty of movement for installation without a flex pipe.
I'll hopefully have my wideband in hand next week too. Then I can dial in afrs.
TSP 1.2 VVT cam next?

you'll prob want a stall also, but there are some days i wish i went with a bigger cam and mine's 218/228 .600 lift on i/e. i just keep telling myself i'll add some boost and itll be ok tho
theres a cc denali on pt with that cam or a 2.2 vvt cam i dont remember but theres a few vids of it on there

its a VVT cam from TSP, a little bit bigger than the high lift truck cam they have though.
218/228 .600/.600 lift 213lsa iirc
218/228 .600/.600 lift 213lsa iirc
The TSP 1.2 VVT is 223/233, .629"/.629", 114 LSA
You think this cam would need a stall?

This may have been said... they make 90* o2 bungs that may work. Hard to tell from the pics if one would help or not.

I wonder if they would affect the O2 readings?
