The turbo on my truck is just too loud. I've switched to a OEM intake, which maybe helped a little, but not much. I have a MBRP 4" exhaust (no cat), and just today put a Corsa muffler on it, which had no effect on turbo noise.

What can I do to tone down the turbo noise? It gives my wife migraines and she wants me to sell the truck!

Have you looked into a Diamond Eye Quiet tone front pipe?

Yes, but I would like some positive confirmation it actually will help. Everybody told me the stock intake would make a huge difference. $200 later, it helped little to none - wife says 5-10% better.

Is it the turbo whistle you find annoying or the hair dryer type sound the exhaust makes after putting on the exhaust? I like the whistle the other is a little annoying at times.

My thought is your exhaust. What type of muffler did you install? Some are much quieter then others.

I would try putting the cat back on. Removing the cat made a huge difference on mine, the turbo is much louder without it.

have you looked into divorce lawyers? Put stock exhaust on it and put your cat back on.

I noticed more turbo noise after I installed my 4" mbrp downpipe back exhaust system.

I wonder if it will be even louder when I put on my mbrp downpipe. :D

I agree, removing the cat makes it louder.
