is a glasspack louder than flowmaster? i'm lookin for loud and beefy

 

its a little off topic but ur running no cads?

how did ya get past the o2 sensors?

 

glasspack i slouder, but will sound like crap at high rpm's..


According to your current sig, its what you have.


Flowmaster will sound alot better.


And if you have NO CATS, i feel sorry for your valves, your truck must be a a brick on acceleration.

 

everyone says i srewed my performance but it is fine and i have talk to a few local mechanics that say it wouldn't affect my truck. there are certain computer systems it hurts,but not mine. nothing happen to my sesors. all i did was pound out the inside of the cats and then put the sensors back where they go.

 

Those mechanics are stupid.

 

are you a mechanic? how would you know? have you done tests? like i said my truck will still rip tire, even better than before. i'm not being rude just getting opinions and trying to learn.

 

glass pack will be loud. but sound like **** just get a 40 flow.

 

Actually, i have done test. Want to talk to a ford certified mechanic? I can ask him to post here. His name is Doug.

 

trust leo... he knows all lol


Hes got a point... our trucks love backpressure, so by taking the cat out... it may do more harm than good...

 

Backpressure builds torque, by removing the cats, your making a big open hole, leaving no backpressure there for torque.

Burning up valves.

But hey, its your truck right? Sorry i stirred up the pms.

 

Flowmaster will sound beefier than the glasspacks.

 

back pressure = evil. u need exhaust gas volecity to properly assist in cylinder scavanging. opening up an exhaust so there minimal restriction wont hurt anything, increasing the pipe diameter to a size to large will.

gutting the catalyics is silly. modern cats are a very good flowing design. ur fuel trim is based off what the o2 sensors read. on obd-2 vehicles there is an upstream (before the cat(s)) and a downstream (aft the cat(s)). the pcm reads how well the engine burned the A/F mixture and then how well the cat works.

and i havent heard of anyone burning up an exhaust valve unless they were running like 6 inches of pipe off the manifold...heh. like my friend did in his 83 f150...

if ur looking to get rid of an emmisions device that is evil, id remove the smog pump and EGR. those bastards are bad, especially on older trucks.
