I want to use the existing stock piping and put an aftermarket muffler in place of the stock one. What is a good muffler that will give me a little louder sound with less restriction? I would like to do the install myself. Ok to just use clamps or should I just take it to a muffler shop and have them install it? I am not planning on upping the horsepower any time soon because I can't afford a new tranny so I don't think a whole new system would be neccesary. What do you all think?

 

the advantage to doing it yourself, other than its pretty easy, is that before you go out and buy a muffler, check to see if you like the way it sounds without one. alot of people seem to be satisifed with removing theirs but leaving the resonator on. gives you a more aggressive sounds but it aint obnoxiously loud. just my $0.02. good luck with it.

Straight pipe it! Turbo to tail! 4"! Stainless steel!

Okay, all a matter of personal preference really. I like my set-up very well. From what I have found, you may want to go ahead and lay down the cash up front for a system that meets your long term needs and desires, as it will save the $$$'s in the long run.

Rip Rook is a good man to call and discuss what you want. Very reputable. Sorry, I don't have his info handy, but I am sure others will chime in.

Marky, you got a PM

 

Dynomax 4" bullet style race muffler, less than $40. Quiets but doesn't silence...

 

All I have is a 24 valve resonator on my truck, I really like the sound.

 

Thanks for all the replies. I'm leaning toward taking the muffler off and puting a straight pipe in its place and see if that's too load. If it is, then I will put a straight through muffler in.

 

Does anybody know if a muffler with 4" inlet and outlet or a 4" straight pipe will replace the stock muffler? What I am trying to say is what is the size of the stock inlet and outlet of the stock muffler? Thanks in advance. Mark

 

Mark, I put a glass pack on mine after running a straight pipe for a while. I didn't like the drone. I liked the sound though. After installing the muffler, my egt DROPPED about 75 degrees. And it still sounds good (to me). My muffler has a 3" inlet and a 3" outlet. Check my sig for what I have. I don't remember the price but i got it from JC Whitney.

Thanks. I'm going to crawl under there tomorrow and see what size the inlet and outlet are.

 

Here's one that not many CTD guys are using, yet. These mufflers kick butt and sound sweet. Price is right also. http://www.aero-turbine.com/
