1 5/8" primaries with 2.5" collectors. 3" single or 2.25" dual from the headers back with x-pipe.

Only LT's available for these trucks in above sizing is from doug thorley (tri-y design) or Hooker Super Comp's. Hooker's got a 3" collector but that is easily necked down.

 

I know the 3.08's are horrible for my application, but I was comparing the take off from before the headers to now. In both cases, the 3.08's were in it. I was going to install my 3.73's myself, but I figured it would be worth the money so I don't have to mess with it. Just have to get an appointment.

 

My truck is a stock cam 5.3 and it goes faster once i open the cutout...now it is a little ways back so i ahve some pipe after the y but it goes faster and faster the more i open er up.
Oh and i am running pacesetters with the off road y.

 

Does anyone know the specs on the obx headers. I forgot to measure them before I put them on.

 

Where can you find the Hooker LT's for our trucks?

 

Same here, but I believe the set I got was right before the moved to 1 3/4" primaries. The older ones were 1 5/8" which isn't much but will help out a stock truck more on the low end.

Mine still felt pretty good down low, but top end was much better with tuning. I had a friend that did the pacesetters (the new ones) a few weeks ago and his truck is a little slower off the line, but up top it really came alive.

I wish I had a set of the 1 3/4" now since heads are in the near future.

The description in both places says it comes with the y-pipe, but others have had to argue and argue with them to actually send it. And then others still have said that when it came, the y-pipe was kinda crappy. So... I really like the Hooker LT's cause they appear to really have some good length on the primaries, and the price isn't bad either, but they are made with only 18ga tubing. Dunno what Pacesetter's are, but Thorley's are 14ga, and I like that A LOT. But you pay out the nose for em... like $750 or so.

:edit
I'm retarded. Hooker's are 16ga not 18ga.

 

Thanks. Wondering/Hoping these will fit the 07+ NNBS

 

pacesetters are 16ga if im not mistaken..... very nice for the price! atleast the coated set i got were. i also got the ory. the only problem i had/have is that the actual y-junction sits on the cross member and vibrates with the rpms. im gonna have to bend them away. it is driving me nuts. it really isnt that bad, im just a bit ocd.

 

I think the hookers are 16 ga. too based on what I was seeing on their website.
