well i was talking to this guy today who owns a muffler shop and we were talking about exhaust....well he was saying that runnin an X pipe set up and dual flows would increase performance...is this true, and also what im more interested in is this legal....like street/smog legal....

its totally legal if you do not alter your factory cats in any way.

and if you're really serious about exhaust performance then ditch those flowmasters :read:

i HIGHLY doubt you will notice a difference with an x pipe unless you have a serious power adder like N2O or a blower

btw im not saying that you will be able to feel a difference in power between your flow and say a magnaflow either......but if you had a blower you would :crazy:

 

[Joshs2002Silverado]

you say ditch those flows....what kind of exhaust should i run...whats a good brand to to run

im not saying ditch the flows technically, BUT what i am saying is that IF you wanted to make the highest performing exhaust system then true duals, xpipe, and a magnaflow type muffler would be the best. BUT you really dont need all that unless you have other serious mods for your engine.

as your truck stands now a single 3 inch pipe or dual 2.5s would suit you fine without an x-pipe or swapping mufflers. get what i mean?

i personally like the sound of flowmaster, but magnaflow outperforms them. i have a corsa myself, which is the same as a magnaflow but with zero resonance :crazy:

 

[Joshs2002Silverado]

cool...thanks...yeah right now i have what it says in my sig...
Headers, intake, nelson tune, and the flows.....

 

[onyx]

an x-pipe would definetly give you more back pressure for better low-end torque response, just as if you were putting headers on... i would say ditch the flowmasters as well...

 

[03rado]

whats wrong with the flows and an x-pipe

 

[thedj75]

yeah....i always thought flows were the choice of the masses.....whatsa the best performing muffler for our trucks anyway? hmmmm............

Not Flows.

 

[Joshs2002Silverado]

Not Flows.

well everyone says not flows...well if you all hate flows soo much then what is a better brand to run...i mean as far as bolt ons muffler choice aint going to make that big of a diff is it....and most people just choose flows cause they know it sounds good...

 

[02denali]

hey flows have a drown to them. on ls1 tech someone listed a comparison chart that showed flows to be a little more restrictivethan others. if you like the flows then keep them. there are a enough people running good times with them now. there are better muffs out there. i went to an edelbrock which is a good flowing muffler.and know people that have went to the same muff from a flow and gained hp.
x-pipe---if you went true duals then you lost low end power. an x-pipe equals out the exhaust pulses and gives great power throughout.

i mean i'm no dyno but i dont feel like i lost any low end. Seems like i gained a bunch around like 25, got a lil more punch to it. JMO
