Default Quieting Down an EWG

So my Tial 44mm EWG is getting a little loud and obnoxious after 3 months on my DD. I have read many places of people using mufflers or other methods of quieting down a VTA EWG. However, I have not seen an execution of it.

So, Does anyone have any links to a solution here? I am NOT looking to plumb it back into the downpipe.

Prior to getting my 44mm 3 weeks ago I thought I was gonna hate it but I've honestly grown to like it.

on different cars i have seen people use mufflers from small CC bikes. like a pocket rocket or even scooters. if your worried about flow then they makes aftermarket performance exhaust for the same kinda thing. i personally ended up plumbing it back into the exhaust after awhile on several different vehicles....

I had it plumbed back into the dp and actually made more power. I don't think flow is an issue if it's done right

Yeah we've had quite a few customers run our kit back in to the down pipe. If you bring it to a local exhaust shop they should be able to fab it up for you.

another option; link to thread http://forums.nasioc.com/forums/show...1809838&page=3. Supposedly no noticeable power loss (supposedly a tuner confirmed this as a VERY negligible loss, or non existant.)

3" Dom3 XTR
TiAL 44mm EWG
APS DR725 FMIC
GTspec's EWG Header/Up-pipe combo
Custom Dump tube (made by a local company for about $90 including materials)
Catless TBE
Hydra
Hydramist Meth Injection Kit (50/50)
Lots and lots of other lesser/supporting mods

Phil form Element Tuning tuned my car on the Atlantic Motorsports dyno about three weeks ago and the car put down 464WHP/473WTQ. As I mentioned before, the Supertrap worked perfectly! With numbers like those it would be extremely hard to argue that the Supertrap is much of a restriction.

I do have two strong suggestions to anybody who plans on doing this:

1 - Weld the Supertrap to the end of the dump tube. The clamp is a total POS and it would easily kill somebody if it came off.
2 - Setup the dump tube in a way that the extra weight of the Supertrap is somehow supported. I used another clamp, exhaust wrap (for padding) and the down-pipe (for support).

Here is a link to the exact Supertrap product that I purchased: http://www.summitracing.com/parts/SUP-344-2005/

Just curious, why not plumb it back in? That is my set-up and now I don't believe that EWG are actually loud

If you need a sticky to tell you that a 1.5 inch tube, venting exhaust straight to atmosphere 2 feet from your combustion chamber, is going to be loud...then you need to throw yourself off a TALL bridge for the betterment of all humanity.

That one is for you Scotty!! (in spirit, not literally)

Don't plumb it back, grow some balls and deal with it. If you don't like the noise, get a IWG. Making power may require noise. So be it!

So sick of seeing these posts. People crying about their car being loud.

Easy.....don't have a loud car.

Ignore people like this. You are allowed to want your car to sound whatever way you want.

Plumb it back into your DP and if you use a COBB style DP you will also have the EWG gases run through a cat. With my set-up I also then heat wrapped the whole thing.

Sorry to hear that for some noise equals "balls."

Last I checked this morning in the shower, I still have balls

Plumbing it back into the downpipe is looking like a good idea now. I just need to find a shop here in ATL that is willing to do it.

@tazswing, I have an APS turboback so no cat anywhere.

You hit boost that often during your commute?

I don't baby my car, but during my commute I'll go weeks at a time without opening the gate.

It is nearly impossible to find a reputable exhaust shop, I would just try one of those Super Trapp contraptions.

Depending on your EWG spring pressure, you really shouldn't be opening it too often. I have a 17psi spring combination in it, so really I don't "hear" it until I'm well on the boost.

yes, i did it back in the day too. as far as power loss you guys need to think about it. its the wastegate flowing thru it only. if it was restrictive and not flowing good enough it would boost creep. there is absolutely zero power loss with a muffler on the dump tube. recirculating does cause a power loss. its added exhaust volume and backpressure on the turbine wheel.
