If that is your video, it sounds like you have an exhaust leak there somewhere. The loud hiss when you hit the "go pedal" doesn't sound right to me.

 

I just had a 4" turbo back Diamond Eye exhaust with muffler, and love it. It has a nice deep rumble and plenty turbo whine. best part is you can get the whole 409SS kit for around $280.00

call Vivian at Quick tricks and she will help you out.

 

On her website aluminized is 280. SS is 380. Still ain't bad if the quality is there.

 

That was my truck with no exhaust system at all just the down pipe... But i was thinking if a stright pipe just is one pipe from front to back would just the down pipe be the same. Is the back presure and issue or does it not matter on a PSD..... I posted the video as a reference i dont want a stright pipe to sound like that... Please your help is needed thanks

 

I have a 4' MBRP turbo back straight piped and i love it. It has a loud turbo whistle at idle and low RPMs but once i get past about 2500 rpms it growls real nice.

 

Generally most guys go with 4". 5" isn't necessary till your making over 500hp. There are no back pressure issues, the turbo provides plenty of that. So first decision is cat or turbo back. I'd recommend turbo back, they lower EGTs better. If you go turbo back then you will have to decide on a down pipe size. Some 4" kits come with a 3.5" down pipe vs a true 4" down pipe. Then you can pick if you'd like the cat and muffler in or out. If you can get away without them delete them. Diamond Eye and MBRP I know offer true 4" kits. Hope that Helps!

 

i must have looked at the wrong one. I have the 409ss one. and really like the way it sounds. and Vivian is top notch customer service wise. The Diamond Eye is 4" from the turbo to the bumper

the only thing i will say is Diamond eve leave some extra pipe at the end so you can cut it off straight or cut it back for a tip.

 

this is the kit i recommend: MBRP Performance Series Aluminized Turbo Back - Single Exhaust S6212PLM (No Muffler)

sweet thanks for the help let you all know when I get it done

 

I have an MBRP like the one in Raul's link but I still have the muffler and LOVE the sound of it. DEFINITELY check it out. :thumb:

 

Is that mbrp kit the off road kit so you dont need to use a catalytic converter? I dont have smog testing so i dont need one and want a kit that i dont need to modify.

Also curious as to what the original poster ended up getting and if you like it or not.

 

I just installed that same kit this morning. No cat, no muff, no tip just a 3.5" down pipe to 4" straight all the way back no obstructions. went in really easy 2 hours total and sounds really good!

 

Anybody try a 5" exhaust? Sound difference vs the 4"?

 

Love my 5" Diamond eye on my 05, has a nice whistle to it when at parking lot speed, sounds great at cruzing speed and so much better when you get into it. I went with no cats and was a little worried about how loud it would be but glad I went that route.

 

I literally just did this too! I bought the MBRP 4 inch from ebay for $239(ish) then went to my local shop and had them add a 'resonator' (30 inch long tube muffler) from Magnaflow. I LOVE IT.

The cab is quiet but the sound outside reminds me of a turbine.
