none i work there from time to time just payed for the pipes.
if u want i can bend yall up the same set up for you . just let me kno if urs is lifted or is a 4 or 2 door. it will run around $85.00 for y pipe and 2 1/2 pipes mandrel bent plus shipping can make it where u just clamp it or weld them together labeled a to a and b to b.
we are the only shop in Arkansas that i know of that is specialists in hard to fit systems like the blazers
like the slogan says "No MUFF TO TUFF"
i also can use stainless pipe that is more money tho

the trick is the Magnaflow high flow cat to rid your system of that pop and mandrel bent pipes instead of crushed bent
also alot of carbon in system will make it pop use sea foam and make sure ur trucks not running rich that unused gas is popping

 

what if you cut out the cat and judt put a straight pipe in

 

Why don't you read up on that...

 

thank u!

its bad for Ur truck dont strait pipe it
its illegal to not have a cat on Ur ride
get the high-flow cat and a good chambered muffler like a Flowmaster or edelbrock and Ur good. if u like it more on the quiet side stick with a turbo muffler or a magnaflow

 

Its not that its bad for your truck, its purely illegal unless its stricly an offroad truck or race car track wise.
