I havn't done that comparison.

Can't wait to test the Test pipes. With the shockwave & gamma and see how the sounds change.

Last question I promise Are the prices for the new axle back going to be the same as these guys?

You mean the other parts not released yet? ...I don't know yet.

I need to do a short production run first to be able to answer that.

Ahh what the heck, I'll just get the perforated one. It's not that much, I'm in neck deep already and if it turns out that I'll like the newer I'll just have to add to my MD collection. Let me know if i can buy a pair of the perforated with the rolled 4.5 burnt tips. My new super NA engine is very close to being done finally 1-2 more weeks

Btw, does the MD TP do anything other then just make it easier on the ear? (sorry i lied, i thought it was my last question...)

I prefer to let the independent dyno plots go into those details.

oh man so many choices for motordyne it makes it so confusing to purchase!

makes me want to go buy HKS instead since its just the 1 product if you know what i mean?

i want to buy an exhaust so someone here help me out plz with the motordyne goodies

i want to get the most power so which exhaust should i get?

also, which should i get Resonated pipes, cats ETC i dont care about emissions etc. just want NO RASP and good sound and power.

also, should i get the MD XYZ pipe as well?

thanks for the help

Get the Motordyne shockwave or the Motordyne TDX shockwave. I'm not sure if he's released his tp's yet but they're probably going to sound alot better than everyone elses, Tony mentioned them being "more forgiving on the ears"

test pipes test pipes test pipes!!!!! any ETA? it's the last power mod i'm doing before i get my osiris tune.

I'm working on them now. ...Maybe a couple weeks.

anything for the g37s yet tony? or atleast by next spring?

Any teaser pics of the test pipes yet?

All of the exhaust performs the same. The only part that alters the performance is the Catalytic, Straight, or Resonator pipe at the end of the XYZ.

Sound wise you have to be your own judge, since it's so subjective. I personally prefer the Gamma over the Shockwave, but it seems that most of the people are the opposite. There are quite a few sound clips of the shockwave and gamma on the site and in this thread.

which set up would you suggest for a more exotic mild sound with no drone and very quite in the low rpms

basilcy from low rpm to high rpm = quite to loud?

More sound clips and reviews will be available shortly.
