is it a Denali SUV or Denali truck?

 

Truck

 

ok cool, in stock form the truck should run 15.8-15.9 area maybe quicker if you have the stock 17" rims, I'd say you're probably running a 15.4, but hopefully quicker!

 

Well i took it out today and it ran a 15.2 at 90.7mph
However that was with 550 pds. in the bed and 3/4 tank.
I need to empty the bed and put my mods on so i can see 14's

 

wow 15.2! very nice! I'm hoping to break into the 14's myself

I have a 2004 Denali also, my mods are:
- K&N FIPK intake
- ASM Long Tubes
- No cats
- Magnaflow Muffler
- MTI LS1 Edit Tuning

 

I bet your truck sounds good.. I am just going to put my edelbrock's off of my 03 sierra on and as far as exhaust i am not sure yet I am thinking somthing with turndowns. What mufflers would you suqqest?

 

Yea it sounds pretty good, I get compliments on it here and there.
As far as mufflers, it just depends on what you like. I had dual dynomax bullets on mine before the magnaflow and it was really loud and sounded like open headers. Ive had those, flowmasters, Borla, and now the Magnaflow and out of them all, I like the Magnaflow the best.

 

i had flowmaster 40"s on my 03 sierra but i am thinking dual magnaflows with turndowns not sure yet

 

What was your 1/8th mile time and mph.

Im guessing the air was pretty good. Nice times.

 

ILLNALI, Where did you get your K&N? I thought the one off of my 03 Sierra would fit however it does not. I could get it to fit, the metal shield doesnt want to line up to the one bolt hole. If you could can you get me the model # of the intake Thanks
