I need to get an opinion from yall for a true dual setup on my '99 5.4. How does 2 94306 high flow cats with an H pipe to two 11" (or possibly 14") Magnaflow mufflers turned down sound to yall? It's 2.5" pipe by the way. I am still trying to figure out if I want to turn it down before or after the axle. If you have any suggestions please feel free to chime in. I just want to do this right the first time. Thanks in advance.

 

Sounds alright. Might lose a little low end power but nothing noticeable unless your hauling a 4,000lb+ load.

 

The H will give me a choppier sound correct? I dont want a raspy sound.

 

a little, it'll be as loud as no crossover, but not raspy. Running no cats or no mufflers is where rasp comes from.

My exhaust is far from raspy and its pretty much what your building.

 

Yea I want a system similar to yours. The only difference is that I will be dumping mine.

 

bump

 

why dump?

 

i dont like the look of tips really.

 

at least dump it over the axle. itll give it a better sound

 

thats what i'm having trouble deciding. whether to go over the axle or not. i want a good bit of interior sound.

 

true if u use 2.5",with my 2.25" setup-in my 9k lb van- i tow ~5500 lbs every weekend-my torque band is lower than with my oem stock 3" single exhaust and was lowered in the rpm range...

 

yea, i know 2.25 will boost torque. but i dont tow often at all. and im doing this for sound mainly.

 

u mainly want sound? go dual 11" magnaflows (i would do bullets but thats just me) H pipe, 2.5" piping and if ur set on dumping it, dump it over the axle. itll sound pretty damn good

 

yea thats my plan for the setup. along with high flows.

 

the H-pipe will give more chop
