Do us all a favor and dyno the car instead of posting a sound clip.

I personally picked up 13 hp and 4 ftlbs torque from the addition of cats and Y-pipe. Every car is different, but my Vette usually picked up 5-6 hp on the top end from aftermaket cats vs straight pipes. Also post your fuel/air as mine improved a great deal below 5000 rpm but still stayed around 12 to 1 over that rpm. Typically you see the free flowing effect more at higher rpm were more cfm is flowed.

Thats interesting... Horsepower isn't crazy bad but only 4 ft.lbs. of torque?

Denny what was your baseline and % Change?

:iagree:
Any dyno results between the test pipe and HFC?

Unfortunately I don't know of anyone who has dynoed with these test pipes yet. Wanna be the first? :)

:icon18:
Working on it!

what's the price on these ? PM ME to 77566

I don't see how these could outperform completely open test-pipes.. Not unless the VQ likes more back pressure that close to the engine or something.. or Berk was just lucky to hit the sweet spot. I was going to just pick up some test pipes since there's no emission testing in Florida.. HMMM.

DD can I get a PM on pricing and availability + S&H? Also do you have Work GnosisG2 wheels in 19s?

PM sent :).

DDM,

Can i get a price with shipping to 38017? Also, where did you get the BERK sticker's i've seen on your car, they look nice. I wouldn't mind having a pair of them myself.

Thanks,

PM sent.

So has anyone tested the test pipes yet?

Not that I have seen. I know I have sold a few sets...

Well I just ordered the test pipes and jwt pop chargers. I am going to try to get the old lady to let me spend the money on a before/after dyno of the baseline then the pipes. Hopefully she lets me but from what I remember Dyno's are cheap to use. If I get those rims sold I guarantee I will get the dyno's done
