6.7 exhaust

[PTSUPERD]

you guys ae overthinking this. 4" has more of a hiss , 5" has more of a rumble. the tone differential is high to low . 4" a bit higher and hissier , 5" a bit lower and a bit more rumble. i absolutely prefer rumble. both my power strokes have 5" no muffler, wouldnt change for the world .

^ what he said.

I run a no muffler Flo Pro 5" turbo back. No drone, just a nice throaty rumble. Not loud or obnoxious in any way. Really glad I didnt do 4" or a muffler.

Anxious to see how it sounds with the 66/70 I have on the way.

Mike's exactly right...... 4" for hiss and 5" for rumble. You also hear more turbo with the 5" in my opinion.

I'm calling you wed mike when I have a day off. I've got some questions

I guess I could have just posted this... mine with the AFE 5" Straight. Much deeper than a 4" as I've had both on my truck.

Only video I have of my 11 with the 5 inch, was shot for a fan pole ad.

yeah but that sound is NOT what people can expect with a stock turbo. hence why i didnt post mine.

True but the rumble at idle is somewhat similar to what it sounds like with a stock turbo.

Just trying to help a brother out.

Anybody run the flo-pro 5" duel with 6" tips? Curious on how that sounds and looks, that's kinda what I'm leaning toward putting on mine

I got 2 vids on YouTube of mine. Search 6.7 powerstroke flo pro. I got a cold start and another with some revs. Love my dual 4" setup!

Started it up to move over and get a bath. You get the idea though. 2013, Flo-Pro dual 4" no muffler, stock turbo/fuel.

Guy by me has a 14 with a 5" single straight pipe and his turbo is definitely louder than mine with the dual 4's.

Thanks guys. I appreciate y'all doing that. I think the 5" sounds better

 

[LMPirate]

Really like the duel look. Thanks for the videos, pretty sure now that's what I'm going to get for mine

 

[bhudson]

After thinking about it a lot and looking around, I'm not sure I like the duals on a diesel truck since it doesn't seem to serve any real purpose other than looks

 

[Tom@BigTimeKustomz]

It's different, that's why I did it.

Yeah I hear you. It is better than stock and sounds better too, I just think after looking at A LOT of YouTube videos and stuff, I like the 5" single better

Agree. You don't see it on too many trucks

Okay sorry fellas I'm new to the forum, but what's exactly is the deal with the exhaust systems on these trucks, I have a 15 6.7l and all I hear is don't touch the exhaust, I'd love to mod this truck, I feel it could be a real bada** around my area I just don't know what to do. I don't have tons of money but I'd still like to make this thing ride out on most of the local street cars.
