LS4 Performance - DTH and Hogan DP

I was just curious if anyone knew if Hogan Performance DP11S or DP7S would work with DT headers if not does anyone know where i can get a Mid-pipe with a hi-flow cat assembled already? thanks

Just cut the stock dp to fit.

I would not.

The DTH downpipe should be 3"...i'd pickup a 3" highflow cat of your choice and weld it in. This would be an optimal solution. I'm not sure anyone makes a downpipe for DTH with a cat already installed...though I'm sure hogan would want to or be willing to try.

Then Does someone make a Catless downpipe?

I think the guys that had the DP and then added the headers had to cut ALOT of the DP off to allow the collector for the headers to fit which pretty much makes it useless IMO.

Yeah I can see that basically I'm wondering what i need to install the headers. it seems ill have to weld on a flange to the S pipe I'm just not sure if i need to custom fab something or if theres something that will bolt from the DTH and connect to a Stock exhaust or Magnaflow catback. thanks guys

All you need to install the headers is tools. If you bought them new from Doug Thorley they come with everything you need to bolt them up to the factory exhaust. Now if you bought them used post up some pics so we can see if you're missing anything.

How do people with the DT headers get rid of the u-bend?

Straight pipe... Actually it isn't a u bend. There's an indentation where the o2 is.

This is everything that came with it. I think I'm missing a O2 extension and bolts the connect the Front header to the crossover. you guys think that S pipe will cause any problems maybe being too short? any info on what the bolt sizes or where i can get a extension would be awsome.
