Exhaust ideas with TRD S/C?

[8WOOD]

I've been thinking about some exhaust ideas for my truck. Personally, I want the truck to be sleeper, meaning I want it sound pretty near stock, but I want to get the most performance gains without having to mess with the stock manifold( no headers, they sound too good) Here are a couple of ideas


1. Cut out the rear cats on the stock exhaust and replace them with electronic cutouts, thus i eliminate the second set of cats.

2. Buy the URD Y-Pipe and install one electronic cutout just after the Y-pipe.

3. All stock exhaust (no y-pipe) and a electronic cut out after the stock y-pipe.

4. Does the URD y-pipe with everything else being stock make the car louder?

Once again i want to keep it the sound as stock as possible with the cutouts closed--but want the most performance gains

Tell me what you think. Thanks

Keep it simple. DTLH headers, URD Y pipe, and use 2 magnaflow mufflers to tone it all down.

So just to make sure, you want it to sound near stock then when just driving around, but when it is game time you don't care how loud it is. Is that correct? Or would you rather it sound quiet no matter when, and still have the best performance?
If you want best flow,for performance, you'll need the y pipe and headers. Then to make that stay quiet you need the equivalent of the spare mufflers,that Grumpy posted in the rasp killer thread, to keep it quiet. 3" straight through and a little longer than three feet end to end. If it silences a Viper, imagine how well it would work on these trucks.

Any type of mod you do will make your exhaust louder a tad bit. The more you add, the louder it gets.

Yea I want it to be louder at game time, and free up "some" breathing for the truck with the supercharger. I'm not sure the sudden change in back pressure from opening the dump valves on will mess with the ECU. I'm hoping it will not.

I want to avoid changing the manifold with headers--I just don't think they add enough for the nuisance they cause: installing, louder exhaust, raspy exhaust, random exhaust leaks from headers.

I guess my question is--will eliminating the rear cats (y-pipe) make the sound abnormally loud?

I have the JBA 2.5 cat-back.. stock everything else (headers, cats) the set up is slightly louder than the stock it has a real nice mello tone. and it does not sound like it has a flowmaster or any chambered muffler.. the muffler with the JBA is a magnaflow (I think) anyways it is a straight through baffled muffler meaning it has a perferated tube going straight threw the muffler and it is stuffed with packing around the tube. this gives it a straight threw super low restriction with a really nice tone.. i love the tone of these pipes.

im not a big fan of rasp and do what ever i can to eliminate it. when you start to remove cats and junk it will start to get poppy and sound like crud (IMO) if you keep the stock muffler and remove the cats or get the URD Y-pipe i dont think your stock sound will be very nice i think it would have a high pitch poppy rasp...

i would recomend gettign the JBA it has great performance and has enough back pressure to get you off the line, plus you wont have to deal with cut outs (electric or not)

or doubling up on the mufflers if your gonna remove cats and use cut outs

i had a buddy that had a cut out on his chevy, when he took it to get inspected the made him put a metal plug in the outlet of the dump..

What he said! :top:

Getting long tube headers will free up power. Especially when you are F/I. Being F/I also eliminates the rasp

I have the JBA shorties, stock y and the URD 3" with the turbo muffler and I must admit, it is pretty damn quiet. No rasp and a deep throaty sound when it opens up.

URD Y pipe with URD or magnaflow 3" cat back I would say.....

yeah, only the LTs you will see rasp and probaly have to go with a second muffler in front of the main muff like most do (Gadget). That of course is if u run the Y pipe.

I see... so taking out the rear cat converters will make its a lot louder. I'm still sure i want to just change the rear muffler out cause it will sound like it has performance mods. I just took the stock catback off to mimic what it would sound/run like with Electric cutouts. ITS FREAKING LOUD, and builds boost really fast and builds about .5 more boost, and freaking rips the tires loose with rear lockers in like never before; however, when not building any boost it suffers badly. I can tell it has lost alot of low power when not in boost about 2-2500 rpm's. Hence it struggles going up a small hill when crusing alog and wants to shift down.

So maybe it would still be cool to have cutout for WOT. I think i'm just going to keep everything stock for now and put a Electric cut out on the stock REAR exhhust just before the muffler.

You wont see much from taking out the rear cats. The sound will deepen a tiny bit, but not much. If you want mellow at cruising and loud at WOT, then do the long tubes, with stock y and catback (after market) with resonators and turbo muffler.
