Very mellow - slightly louder than stock maybe (don't really remember "stock" anymore!). At WOT they are still quieter than the v2 shockwave but obviously they are both straight through pipes at that point, so both way louder than stock. Still, I suspect it will be too quiet for most folks. I like the fact that I can now listen to music at low volume levels and use bluetooth to carry on phone conversations without issue cruising around town.

 

I'll be gone by the time zdayz rolls up. Raj, I love all of your experimentation.

 

Soooo nobody has the TDX v2 on their built block turbo setup?? lol

 

I do.

 

Built and boosted with NVIDIA and you can't hear my car at all until the wastegates open.

 

Oh haha. So it wasn't the full 3" setup correct?

 

I've had both. First I had the 2.5" primaries that opened up to 3" and then I got the full 3" set up. They are quite different set ups. The 2.5" uses the XYZ pipe that takes 2.5" pipes that come together to form a single 3.5" or 4" pipe and that single goes into a muffler that splits out tp two 2.5" pipes that then expand to 3". The 3" uses separate 3" pipes that goes to a dual 3" in/out X pipe muffler.

I also went from the shockwave v1 axle back to the v2 and now also have had a custom muffler axle back set up fabricated...

 

How did the full 3" sound? How loud was it? Does it really not have any drone? How is it when cruising on the highway? Tolerable?

 

The sound for both versions really depend on the axle back components you put on it. The shockwave v2 (with the side resonators) is a very clean tone, modest at cruise but loud at WOT and no drone to speak of. The shockwave v1 is similar to the v2 but it has significant drone below 2500 rpms. My new custom Dynomax VT axle back has no drone, is very quiet at idle and cruise, and moderate at WOT (i.e. quieter all around).

I think 95% of folks will love the TDX 3" with shockwave v2 axle back. I'm very conservative when it comes to noise and although it is still a bit too loud for me, it is a wonderful note for spirited runs.

 

I bit the bullet and ended up purchasing the Full 3" TDX v2 for my G35 coupe. I'm just hoping it wont be too loud when cruising on the highway at 80ish. Do you think it might be an issue?

 

Anyone concerned with noise shouldn't do 3" piping.

 

whoops? Lol. This is the only video I could find.

I think highway cruising with the v2 is very mild. Getting rid of drone is key! After having some time with the Dynomax VT, I will say that there is a definite small hit in performance. Turbos spool slower and max power is down about 15 whp - not bad but it's there and it's across the rpm range.

 

Not bad at all! in not a fan of the new nismos body but she sure is clean and sounds great!

 

thing sounds way clean. I like.

Recirc wastgates ftw

 

would you guys recommend one of these mufflers on a NA Z? i want to buy the single 3" and dual outlet and get it fitted in the position that the stock muffler sits in. thoughts?

 

Umm just the muffler? Why not just buy the whole system and have a sweet dual setup. The exhaust sounds like a beast on my car. Especially with the cams.
