i have a 1986 f150 l6 i wanna put dual exhaust on it but will i lose compression in my engine?

 

No, just depends what kind of dual exhaust, true duals? or a dual outlet muffler with tips?

 

i plan on having 2 pipes running out from under the cab

 

so.... your saying what, are you running 1 muffler with dual tailpipes? or converting to true duals?

If you are unsure of the difference well true duals deletes the Y pipe and pipes with either an H pipe, or X pipe are fitted and two intermediate pipes are ran back, with two mufflers instead of one.

You can get the same sound gain with a single muffler and hold better low end since its not a true dual.

 

 

i thought the I-6's only have one manifold, so theres no way you can possibly make them a "true dual"

 

Good point, i'm used to dealing with V style engines on the forums I discuss exhausts on.

A simple Single In Dual Out muffler will do the job here. I would suggest a Flowmaster 2 chamber in particular.

 

no one listen to darren. he doesnt even drive a ford. hes got a Toyota Prius

 

I'll drive a Dodge before I drive a Prius, cruel cruel

 

ha, its all good man.

just thought i was going crazy there for a second

 

with a clifford performance header you can

 

i stand corrected then



those are pretty cool. never seen em before.

 

and the '93-'96 300ci/4.9 Liter motors came with split manifolds from the factory...
