hey guys just got a before and after dyno of the invidia test pipes, overall very impressed with the power, definately could tell a difference with the power, its the only mod that i have been able to tell a difference in so far, here are the numbers, i have an auto Z with injen CAI, exhaust and skunk 2 plenum spacer

 

no show on el picturos

 

just got em up sorry

 

you didn't even post up gain numbers, this thread is worthless !!! comeon.

 

the first dyno is with stock cats and the second is with test pipes, l@@K


stock cats: 238hp/220tq
test pipes: 241hp/227tq

 

thanks for adding it. not bad. good tq gains!

 

pretty nice gains all across the board, thanks for posting.

 

I don't know if +3hp +7TQ is worth destroying the environment.

 

hippie hahah jk

 

nice gains you got there ,i wish that test pipe would never rasp .

 

lol

tell that to the 18 wheelers spewing out diesel smoke with no emissions regulations whatsoever

1 of those 18 wheelers = about 2000 350Z's without test pipes

 

Rasp is your friend, everyone loves Rasp. Jk

 

With a screen name like Biochem I wouldn't think you would be too worried about that. J/K

 

Those hp and torque gains are at their peak. There appear to be even higher gains across the entire rpm range. Not bad!

 

Nice gains! I loved it when I installed mine. definently open up the lower-end powerband for me two! Got a weird spike there are 4300 rpms??? And the rasp isn't as bad as everyone on the forum makes it to be.

 

Impressive torque gain.

 

thanks alot, i can tell a big difference in power, thanks for putting the dyno up on the page, i dont know how to do that yet lol, will have more dynos next month with new exhaust, headers, and the new AEM piggyback unit thats coming out!!! cant wait

 

Forget the trees, the Federal fine for removing cat's is 10k for each cat removed

 

Am I the only person who thinks those are terrible gains?

Can you really feel a 1.25% average increase in HP and a 3.1% average increase in TQ? I've seen dyno runs on stock Zs that vary by more than that without changing ANYTHING! That's like saying you can tell the difference between a 50 degree weather and 51 degree weather.

I'm not trying to rain on your parade, but I'm thinking you need to add a few more bolt-ons before you'll start to notice (and feel) a difference.

 

Hell no it's not, lol. Long live environmentalists!
