hmm well ive been meaning to put a muffler on my truck cause its a little loud.

ok what am i saying. sounds like a damn racecar loud. but anyways. im thinking of replacing my 1 precat with 1 highflow. how much louder would that one side be since i have trueduals?

and could i use the stock o2 ? or would it have to be moved?

is it bad for the engine in any way?

comments on this idea? its dumb i know.

 

the goal is to keep the exhaust equal on both sides...

 

Yeah you should have 4 cats. 2 which are your precats and 2 that are your rears, that is unelss you deleted some

 

So you have your two small, front cats... You want to replace one front cat with one highflow? If that's what you're asking, then yes, dumb.

I would leave the front cats alone as they're smaller and louder than highflows, unless of course they go bad.

 

Just cut the last 2 cats off. Having one side unequal to the other is asking for trouble.

 

^ agreed..keep it all equal

 

hmmm anyway to go louder with out messing with my precats?. since its all i have left lol

 

Delete the front cats or get longtubes... Either way you're going to have to move/mess with the downpipes...

 

If you sound like a race car as is and still want louder, then you will have no choice but headers. Unless you wanna dump it and make it louder inside only or side exit before passenger tire to make it louder inside and a little outside.
