04 Straight Pipe
 

i have an 04 extended cab lb7. what size straight pipe should i use going from stock? i dont want it too loud just want a good diesel tone.

a straight piped LB7 is goin to be loud. I dont get your question though :s: If you want to know the size of the stock exhaust it is 3.5". If you want to go to a bigger exhaust it depends on what you want to do to the truck. it dont matter if you go with a 4" or 5" straight pipe its goin to be freakin loud.

a 4 inch with a muffler would be good for ya

whats the easiest way to straight pipe it with the curve pipe that goes under the cross support in the frame at back of the cab?

what?

My lb7 is super loud with a muffler delete pipe (straight pipe)... Sometimes wish it was quieter, but at times its great to pull up beside a Geo Metro with windows down and fill that little matchbox of a car with black smoke... Oh, the people love it :w2:

I've been told that a four inch sounds better on the lb7, but i can't really recommend either, being that mine is 3.5" minus muffler... but i'm also happy with mine as is...

I have 4" straight. Its loud and will always make people head's turn (or in some cases grab onto each other) if you romp on it...

agreed... :w2:

I have a 2004 LB7 with 4" outa the turbo and is LOUD!! with two 6" stacks I made the exhaust with a section that I can unbolt (made with car header collecrors) and bolt in a resonater for road trips and keep it loud in town!!

I can install and remove my muffler in 10 minutes..
