Mark when i got my stack it was 48" from the tallest point and i cut it to 41"(should have been 42") so if ur gettin them from GR u shouldnt have to re miter them! They are measured from the tallest point, so they have plenty of trimming room!

ok I just checked mine and there is no way you can trim the bottom of the 48" stack to make it cab high...the riming would have to be done on the miter side....other wise your still stuck with the 36" stacks.

while I do agree a full length stack would look cool when you look in the bed....I also must say you cant really ever see the 5" neck down unless you right there in the bed anyway....so it's kinda a wash.




a untrimmed 48" stack will be 4.5" above the cab!!!!!
and the miter is the only stack that I can modify myself.

Mine came without the tapper at the bottom and was 48" from the top of the stack to the bottom, so i had a 6" miter at the top and a 6" bottom if this helps any! Ill try to take a pic of mine but i dont know how to poat pics, so if u could walk me through it id post a pic of mine!

got any pics of your trim job??

my 7" GR stack only has about 3-4" worth of 5" on the bottom neck down...I dont see how you could mount the stack if you cut off the 3-4" worth of mounting tubing???

OOOOO now I get it your stack does not neck down to 5"....so how did you make your pipe connections??
did you just use adapters??

I just looked it up in my GR book and it does not list ANY stacks under 72" that are the same size all the way down....the only stack that does this is ALL the 5"ers and ONE 6" version(the one you bought)
so trimming the bottom of the 7" stacks to 42" is out.

I took a piece of 1/8" sheet steel and cut a 7"x7" square out and then cut a 5" hole in the middle for the 5" coming through the bed, then i took a 6" ID coupler and weled it to the plate for the stack to set in and used a band clamp to seal it at the bottom! Under the truck i have 4" from the turbo back to after the cat then it blows up to 5" into a short piece of SS flex pipe into my solid elbow and up through the bed and the 7"x7" plate that the stack sits on!! Used all band clamps and it looks great!!

DANG IT!!!!!!!!!!!!!!!!!!!

I am going to call GR and ask them if they can make me a run of 42"ers??
I know they probably wont but it's worth a shot

Bswope

I dont see why they wouldnt, but there is probably a good reason if they wont! Let us know.............

I talked to GR they are going to run me some 42"ers!!!!
I will probably have my whole order filled with the 42" versions
stay tunned

Bswope

NICE.......... i want a price on just the 7" miter stack, are u gonna get any in chrome... and do u have any clamps other than the STAXX?

Ok I did some more measuring and I have come to the conclusion the 42" is way to short?!?!
my stack is 45" from the bottom of the bed to the top of the cab.
when I say "top" I mean the highest point on the cab.
the round part of the roof goes 2-3" higher then the 3rd brake light..so to me that is "cab high"????

if you did 42"ers the very tip of the miter would be level with the 3rd brake light.....that is not cab high IMO.
I had my stack that low and I feel they look and sound better if mounted a little higher.
I will get you guys what ever you want..I will get 12" stacks if the what the masses want.
but what do you guys think??
I may buy a 48" and mod it so i can show you what the two different heights would look like??

I didn't vote because I didn't see the option that says "too many choices".

well in that case i would prefer a stack that measures 45" then begins to neck down so it would be a full dia. length stack in bed then transitioning right at the bed line into a smaller pipe. clear as mud
