Well they were supposed to arrive last thursday, but the driver couldnt find my house so it was rescheduled to today. These are the stainless steel 1 3/4" stepped to 1 7/8" primaries with a 3" collector and emissions. Also included is their 3" ORY. In the 4th pic of the collector, that is all little cardboard debris from shipping.

Lookin good.

what sort of setup will you be using that on?

chy20k1

how much did the headers and y pipe run you?

Turbo6

The headers look great but I'm a little confused on why the large 1 7/8" primaries that go into a single 3" pipe on the y-pipe. Seems like it defeats the purpose. Also, do they offer the headers coated?

As of right now the setup is going to be on a mostly stock 94 LT1. I have the stock cat-back exhaust piping with a flowmaster muffler welded in place of the stock one. I'm sure I'll get a few replies telling me that's too much exhaust flow for a stock LT1, but I plan on doing some AFR heads and a big solid roller along with some nitrous in a few months so I wanted to get the right headers first time around. The restrictive stock piping with the flowmaster muffler will help create some backpressure (I hope??) so I don't lose too much low end TQ. The stainless steel longtubes stepped to 1 7/8" from Kooks are $868 and the y-pipe was $220. Horsepower Engineering had a free shipping special so total was $1088...ouch. I purchase only the best products available and I am positive I will not be dissapointed. The word from Kook's is that you can replace all the spark plugs from the top, so it SHOULD reduce times to about 20 mins or less. Install will be done partyly tomorrow and Thursday. I will have updates and install pics when finished.

EDIT turbo6 I figured that 3 1/2" collectors would be too much, and I do not want a true dual exhaust..dual cutouts will also be installed when I have the y-pipe welded up. And yes, they offer these headers coated.

In my mind, I was thinking that a dual 3" y-pipe into a 4" collector would work better. Do the 3 1/2" collectors exit into 3 1/2" pipes in the y-pipe? I think the 3" collectors are plenty big enough but you cut flow in half as you enter the catback and for such a large header I would think that you might lose some of the gains due to this. Either way they are nice headers and I'd be interested in seeing someone do a back to back test of them comparing them to the standard Hooker/Jet Hot 1 3/4" longtubes.

I'm not sure if Kook's even makes a y-pipe to go along with the 3 1/2" collector due to the large size. A 3 1/2" y-pipe would have clearance issues, and it would have to be reduced to mate up with a catback anyways. (Unless you have a huge 3.5" or 4" mufflex cat back) I beleive Kook's suggests that a true dual system be installed with a 3 1/2" collector, but again I'm not sure. I decided to go with the y-pipe instead of true duals because cops are dicks around here and the flowmaster will quiet it down a bit (80 series) But I can always open the cutouts..

I really like the design of that Y pipe AND those headers. I'm DEFINETLY getting a set to replace these jet-hots sometime

MEAN LT1

Im still worried about plug acess.

SS MPSTR

Just curious, why would you replace something that works just as well? Are your JH already failing?

SS MPSTR

That was the primary reason the FLP's were a sub-par header - for the price, the access was horrible among other things.

madhatter

Mine did lol. The AIR pipe cracked right off. I also plan on getting these headers by the time I drop a new engine in. 135k and it is starting to get tired.

ooo soo sweet, i can't wait to get a set. let us know how the install went and a sound clip would be nice.

are those headers legal in california?? since they have smog equipment on it, i hope so
