In a couple weeks or so, I'll be making the appt. to get my exhaust done.

Remove the Y pipe, 2.5" pipe, 14" DI/DO Magnaflow muffler built in X pipe. Tailpipes out the side behind rear tires facing out the side.

I'm looking for a clean cut, powerful big block sound and I feel this setup will give me just that. My only question is how will the X pipe affect the sound? I see alot of people running x pipes with true duals and swear by it to balance everything out.

 

Having the crossover in the muffler will help balance the sound a lot. However, a dual outlet muffler will probably get you a very good sound for a lot less money. It may also be louder. Which engine do you have, only the 460 can really justify dual 2.5", the smaller engines just can't displace enough air to keep the exhaust moving fast enough at low RPM, and your low end suffers as a result.

 

5.4 Don't tow anything, just occasional stuff for the family and monthly trips to the landfill.

 

I would skip the true dual, I don't think it's really worth the money. I agree with bearriver in this situation.

 

I appreciate the info! After listening to many youtube vids and searching forum posts, I'm pretty well set on true duals. I know I will sacrifice some low end power for sound and I accept that. I prefer the sound of true duals over other setups. One man's opinion.

So I should use an X pipe? Just need a few paychecks to build up the funding.

 

Motorhead351 has an X pipe on his true dual set up. When he revs his motor, it gets quiet. If you want sound quality and decible quantity, I would avoid the X pipe.

 

Is he running mufflers?

 

Yes. I don't remember if they are dual factory mufflers or other. You should PM him. He has vids.

 

Speaking of vids. Listen to this F150. About the sound I'm looking for, just not quite as aggressive.

Truck sounds good at idle but weird when he revs it. Kind of like it doesn't have as much "bark".

Maybe the X-pipe isn't the way to go??

This is my favorite F150 soundclip here, Roush catback w/ everything else stock:

Not trying to sway you from what you want, just another soundclip.

 

Sounds to me like the OP doesn't want an Xpipe.

Never heard a V8 that didn't sound good. -shrug-

 

While youtube is better than nothing, the sound you get depends greatly upon your computer speakers as well as the equipment that was used to record to the sound. So what I am saying is that depending upon camera location, camera model, and wind conditions etc., some systems might sound worse than they really are. I would base your decision more upon hearing the vehicles in real life than upon what you hear on youtube.

 

BearRiver, have you ever heard a V8 you didn't like? If so, I bet there aren't many. I can count on one hand the number of V8's I thought didn't sound good. Even then they sound better than my I6.

I think using common sense and choosing the right muffler depending on decible quantity is the biggest thing. The V8 will do the rest.

 

To be honest, yes. But that is a matter of opinion. I have never heard a V8 tone I didn't like, but I can't stand raspiness. But that is just me. I have never heard a V8 truck I didn't like, but a few V8 cars that sounded awful.

 

go with an X-pipe. uneven flow could screw with your valvetrain with one side of the piping being a little longer than the other and a little different pressures. the X pipe and straights will give a very nice even sound, and won't cancel out any sound you're looking for.
