exhaust true dual

[Cheaper Jeeper]

can you go to big on these trucks with exhaust? im going to go either 3" or 4" with a straight through muffler but will i lose torque with going to big of exhaust?

Nah, that's gasser thinking. On a gasser a little exhaust backpressure is necessary for max torque. On a diesel that isn't the case - the more free-flowing the intake and exhaust the better.....

You won't lose torque but with a straight through muffler and 3or 4" exhaust you will lose the ability to hear without hearing protection (-:

I say thats BS

As stated earlier in my post I can have a normal tone conversation with somene in the cab. To add more to that I can have a conversation on my cell phone using the bluetooth in the GPS.

Perhaps you have not heard a Gibson muffler.

I have a straight through muffler as well, it is oval, but you can look in one end and out the other. 3 inch both sides and full 3 inch exhaust. I can use a cell phone etc. no problem. With no A/C though, at 55 MPH or better it is tough to hear because of the wind noise!!!

Back to the origional post, I think the 3" system with those mufflers willl sound TOUGH! Let us know how it sounds, I assume that you are having tailpipes all of the way out the back. If so the sound in the cab will be just fine.

The key is the big pipes, with anything smaller like 2 1/4" or 2 1/5" you will get rapping. the bigger the pipes the mellower the sound.

Keep us posted,
