17.5 HP and 15.5 TQ gain from a catback?!?!?! YES! got the Dyno's to prove it too!
 

Hey everyone, I picked up the MD shockwave Dual Ti cat-back exhaust system.
Tony @ Motordyne really knows what he's doing !
Here are some pics, and you will not believe the gains I got with this! I posted the dyno's up as well so you can see for yourself!
We ran 3 dyno's on stock exhaust (w/test pipes) and 3 dyno's on MD Shockwave Dual Ti (w/test pipes)
Greatest investment ever! I look forward to what's next from Motordyne! :biggthumpup:
I'm from the G35driver side and I just had to share these dyno's and pics of this beautiful exhaust because I know MD makes them for 350z's as well! :skidmark:

Aiya.. embedding doesn't work, but this is link to Youtube video of Dyno! http://www.youtube.com/watch?v=tmuG-yJdUnk

Beautiful exhaust. Photos appreciated.

The 2nd graph is weird,

The power curve is showing 222.96 hp and where it says runfile_002 says 232.28. Anyone else seeing this?

Are you referring to the highlighted pointers at 5900 RPM?

Very nice

Ah thanks, you just cleared it up for me. Its late and not thinking clearly. Nice gains I might sell my Injen for this one.

Tony... at it again. Sweet sound too!

Holy Shiznet Thats Loud!!

Congrats on a really kick a$$ set up...are you running headers or just a test pipe back set-up???

Sounds great.

Nice! Have any in-car or drive-by videos? We have videos of MD's exhaust with HFCs, RTPs, and now TPs thanks to you :)

backfires sound sick. What all do u have done to the car?

WOW AMAZING!!! great product

the product is amazing... love the sound btw op!!!

Do you have a tune?

Similer to the results i got. I only got 9 , but i went from an aftermarket system(tanabe) to motordyne.

where can i buy this exact setup? the website says they are out.

PM Tony he will take care of you. Hydrazine is his name on here

Continue to read the graph that looks to be area of highest gain.

how did you come up with the 17.5 HP gain?


did you take the lowest stock number vs. the Highest Exhaust number?


wouldn’t that be kind of skewed. shouldnt it be

the highest stock HP vs. the Highest Exhaust HP?

or

the Lowest stock hp vs. the lowest Exhaust HP?
