At first, I had a FM American Thunder system on. I exchanged the 50 series FM muffler with the SI/DO Extreme which I had clamped to the rest of the Flowmaster system. I then decided to get rid of the FM pipes behind the Cherry Bomb muffler so I had 2 turndowns welded right off the muffler. I have a RC so the turndowns are behind the cab which means no exhaust fumes.

The turndown are also much cheaper. I paid $5 each for them. Pipes that go to the back are pretty expensive.

With the turndowns, its a little louder outside, but a hell of a lot louder inside. I drove my dad up to Placid before I dumped the exhaust. He survived but had a massive headache for a day. Now that its dumped, he wont even get in it. Its so loud inside he can't even tolerate a 10 min ride

 

There is a dude on the 2nd gen side getting a Cherry Bomb Extreme put on right now. He's going to do a sound clip when he gets it back...

any risk with turndowns? or could I just get a cherrybomb muffler that would fit on to my stock exhaust from the engine back to the cherry and then get two turndowns if i went with a si do that way if I want to add pipe at sometime I will?

 

I haven't had any problems with turndowns. Just make sure its dumped behind the cab so exhaust fumes dont get inside. I'm running a completely stock setup from the engine to the muffler. I have stock manifolds and stock cat etc. I have a pic of it I'll post up in a few hours if u want. I'm in school now and photobucket is blocked. Unfortunately I don't have any sound clips yet.

 

Mine is 3" inlet 2.5" dual outlet.

I will warn you tho... you might lose a little low end torque due to loss of backpressure. All crazy loud exhaust systems are like that. I really didnt notice it. At the end of the day, it is no slower, sounds insane, and theres still enough torque to do crazy burnouts

 

yea bro post some pics. well would the loss of pressure be compensated for if instead of turndowns went with a cherry bomb and a new dual out section from the cherry on back? or is it just due to the muffler. I figured this may happen but i'm not too worried about it. I'm just in the looking phase but the cherrybomb is definately the way to go.

 

Any time you increase efficiency in your intake/exhaust you lose backpressure. The benefit of the increased flow is that you get better fuel economy, more mid/high rpm torque and more HP throughout the whole rpm range. The negative is that your low rpm torque (like under 2000 rpm) is really a result of exhaust backpressure, so you'll lose a bit of that.
That's why it was important for me to leave the cats on when I put my headers in, to keep a little of that backpressure. Of course, if I ever get the cam & SCT done, I'll have more torque than anyone short ofa CTD owner...

 

I got to chime in on this. If you are looking for loud clear the sidewalk sound, then get the Cherrybomb Extreme muffler. TheExtreme is the loudest muffler out. They were designed for racing and off road use. Warning, They are loud as hell inside the truck as well.

 

here, this will recover your lost back pressure if you go with the dual outs

I have an Aero at3030 on my hemi, and it is quite loud. It sounds better than any hemi I have heard as well. I highley suggest looking into aero turbine if you are doing your exhaust.
