Took my car to "The Performance Garage" which is east of Nashville, with 2.5'' resonated test pipes installed. Chris at "the perfomance garage" has a dynojet. We then did 2, 4th gear and 2, 5th gear pulls. Then swapped to the A.R.T. Pipes, with car still strapped down and did 2 more 4th and 5th gear pulls.

Closing Comments.......

After driving the car a week, It is ALOT quieter/No Rasp AT ALL with the A.R.T. Pipes. Mid range TQ is unbelievable. I am so happy with these pipes, I already forgot what I paid for them.

Now that the car is quiet (not as quiet with stock cats) but still quiet. I need to decide on which motordyne exhaust system to install.

In approx two months I will post dyno sheets with motordyne exhaust, with uprev tune by Chris at the performance garage.

Ps: With the resonated test pipes with 2 sparkplug non foulers and the A.R.T Pipes. I have had no check engine light for 500 miles.

That's cool man, so is that in Smyrna? I need to get on the Dyno Jet and see my true numbers after being tuned on the Dyno Dynamics. You made some good numbers for not being tuned and with no exhaust besides the ART pipes. I might need to trade in my Berk HFC for some of those and re-tune. Did you buy yours through Tony and Chris at "The Performance Garage" tunes UpRev? He isn't on the Pro tuner list at UpRev's site. You might want to go to Forged like I did or Injected Performance for the tune.

the pulls in your 1:1 gear (5th) showed little gains? The numbers are way different from your 4th gear pulls. The 4th gear pull even shows the jump in low tq at 2500 rpms.

Are you tuned? Nonetheless you have gains over test pipes which is good.

Strong car and good gains. Should be at or around 280 w/ exhaust and tune.

Do you happen to have your AFR from before and after? +1 on what 03threefifty said about exhaust and tune.

Which MD exhaust are you thinking about?

Its really hard to tell because the scaling between the two graphs are different. Congratulations on the strong numbers.
