Thump.. You shouldn't have to order any turn downs. Your exhaust shop should be able to fabricate you dumps right there. The guy I go to has made me 2 so far.

 

Its the stainless steel that turns them gold.

I know they can bend me turn downs, I'm just not sure if I want to go with tips on the end of them.

 

hey ill try and remember to get a pic of mine tomorrow. true dual 2.5" into a DI/DO Magnaflow and then dumped before the axle-all stainless mandrel pipe.

 

all i have is a video of mine

and you can see it in the very beginning if you look. its very nice sounding


just for kicks, listen to it and tell me if it sounds deep or not?

 

dude that tip looks bad ***!!!! i would run two of these!!!


here is what i just order im making it so it comes out in front of my right rear tire though.

its a bully dog stainless steel tip 5" out and 4" in, got it off jeg's and it was only $80 half the other one

 

what? is this hearsay, internet BS, or fact? i have a hard time believing that a different diameter for the last 8-10" of pipe can make any noticeable difference in performance.

 

Here ya go-dont mind the beer gut in the reflection.

 

Black3v how does your exhaust sound? Happen to have a sound clip?

 

why are you doing it?

 

Pretty damn loud under boost-sorry no exhaust clip-I have been meaning to do that.

 

Thumper I have the setup your looking for, True Dual Straight pipe(2.5"), W an H, and 2, 4" Tips as turndowns. I'll try and get a pic up, I don't have the lightning style anymore, but the tips in my gallery are the ones I used for the turndowns.

Also, just a word of advice, I'd go with an H pipe instead of an X on our trucks, unless your supercharged or turbocharged.

 

I hear you about the H pipe versus the X pipe since a H pipe is going to provide more torque. I was doing it for the mere sound purposes and I couldn't find a H-Pipe online. I might end up just doing a standard turn down out of the muffler like Black3V's got. .

I really like those but I wonder if they make them in 2.5" inlet.

 

Heres one of my sound clips, i believe this one was before i gutted my precats

It may not make a noticeable difference on that short run but then again the overall system is very short when dumped. And it's far from hearsay and what not but short of side by side dyno I can't say it's fact either. Besides what I've read here, I talked with several exhaust shops about diameters as I wanted to go as big as possible and they all said the same thing about losing low end torque when going big. Go 2.5 at the absolute biggest for dual and the longer the better for torque due to pipe friction backpressure. They said the torque will come in a few hundred rpm later if you get too big and lose too much backpressure. If adding dumped tips you can't see the inside anyway so why not run the 2.5 as far as possible. If this is not true I hope someone will chime in bc I'd prefer bigger diameter pipes for looks and I'm getting ready to change up my system again.

 

have you thought about removing two of your cats? has anyoen else done that? I remember josiah I think removed his precats and it sounded pretty badass. ive been thinking about doing that but never got around to it
