actually no i didnt loose power. I made 235whp on a mustand dyno and 200wtq with test pipes, upper plenum, jwt popcharger, and my old borla exhuast. just had it dynoed again with the same mods except i had the motordyne exhaust. i made 249WHP and 204wtq on the same dyno.. hopefully that should answer your question

No loss of low end trq whatsoever. The XYZ's design along with the exhaust's 2.5" -> 3" piping allows easy breathing for the car providing low end trq as well as high end giving you efficient power gains through all the rpm's.

thanks... the question was actually focused on LOW END torque and power... see you might not have lost max power across the whole power band, but lost power or torque at the lower gears and rpms... your dyno sheet/graph would show all of this...

No I dont' think I lost any low end torque or power in the lower rpms and lower gears but I'll take a look again at the dyno sheets when I get done with class. If you were to loose any, you wouldn't feel a noticeable difference

Will the true dual be quieter or louder? more power out of the TDX??

Its a little louder, deeper and FI ready.

Rob, did you say there was no increase in HP? Over stock or over the HKS? Sounds pretty amazing!

Well I went from the HKS to the motordyne and there was really no difference. But over stock there is a difference for sure.

Keep a look out for my next video, I am getting some berk hfc's put on and a osiris tune on the 22nd.

why did you decide to go with the berks (2.35" i think?) over a 2.5" hfc, like the fast intentions cats? im pretty sure berk dont have a 2.5" cat out (yet)....

TheOtherRob

iTrader: (14)

I honestly don't know, besides the price difference, I didn't really look into size.

i would consider the 2.5" since that is the inlet diameter of your XYZ..

TheOtherRob

iTrader: (14)

Well after getting them in, I decided to measure them. Looks good enough to me. I think I read that berk has redesigned them to 2.5.
