Kooks owners - verify this install (y-pipe)

I just want to be sure other Kooks users show the same install tolerances.

The y-pipe is *awefully* dam close to the brake lines ... and the y-pipe's exit
is tucked way up into the driveshaft tunnel.

Is this how others are positioned? Just want to be sure.

Looks about right. I think your driver side tucks up a little better than mine though. Hard to see in my pic (don't have one of the other side).

My y-pipe had about 1/2" of clearance from the tunnel brace, looks like yours is sitting a little high (maybe just the angle?). Either way, it took me a while to align my catback, which is still crooked. I need to have a muffler shop fab me up something so it sits straight.

I really can't remember and I can't go look. I can say that my Y-Pipe mated right up to my GMMG catback and didn't require any manipulation. The ground clearance was very good.

Is the end of your Y-Pipe angling upwards?

Yes, it is angling upwards a bit. I dont think it's an issue with mating it to
the catback pipe, but it is tucking up in there. Also, there is less than an
inch of clearance from the y-pipe and the driveshaft.

Here's four more photos, shot from the back, starting with this one:

I would guess mine probably fit like that. It was definitely tucked up in there. I wish I could go look to confirm, but I can't.

Mine tucked up in as well. But that's the reason I went this direction. I have much more clearance than I did with the Jet Hots longtubes. I did have to cut some off my "Y" pipe on one side to get it to fit right though.

I used some reflective heat foil stuff around the break/fuel lines whre there close to the y-pipe just for some added protection. Wouldn't be a bad idea.

That's a great idea Ken ... I think I'll get some wrap. The y-pipe did slide right
on, but as can be seen by the photos, the y-pipe is up against the underbelly
on both the driver and passenger sides, so I do want to fab a bracket to
"pull the pipe" down a bit.

BLDun - fortunately, I didnt have to do any customization to the y-pipe. I did,
however, have to grind the header flange in the center on the driver side,
since it wasnt exactly level (it had a slight high spot in the center).

What is this exactly? Do you have any links?

Do a google search for exhaust heat wrap or heat tape and you will find lots of places

How did you attach the round opening of the catalytic converter to the oval opening of the left portion of the y-pipe?

I don't know if this will answer your question, but I'm pretty sure the cats are welded into the y-pipe by Kooks and would'nt require that you attach them to anything. I can't say definitively because my y-pipe is their offroad version, but my y came in two pieces and joined together well beyond where the cats appear to be placed in that pic.

Kooks welds the cats to the y-pipe. The front end of the cat slips over the header collector and is clamped on with the stepped clamps that Kooks supplied.

Thanks for the reply.
Do you know the length on those cats?
What do you think your loss of power is?

I'd say the cats are about a foot long, give or take. I'm not pushing much power, just full bolt ons, so I can't be losing that much. They definitely flow better than stock though.

Green96Z,
Thanks for your help. I installed a pair of Pypes mini cats on my LPP headers y-pipe and it worked out great. The funky smell is way down compared to before and I cant detect any power loss. The exhaust sound is very impressive especially with the e-cut out.
