honestly I cant say how much the borla adds but it is probably the most free flow exhuast next to the HKS. It doesnt have many bends and the pipping is pretty big. The only bad part is it's a million pieces so to get it all aligned right so it doesnt hit the bottom of the car is a pain.

With this set up I'm pulling 382rwhp/353wrtq @7.5psi at 6500rpm

Ati Procharger
1/2" motordyne spacer with all the thermal stuff
RC440cc Injectors (I ran out of injectors on the stock ones)
Greddy E-manage Ultimate
Borla with test pipes

 

Awesome thanks for the info. You said it is extremely quiet even with the test pipes? Also what do you do about your o2 sensors. Do you have a problem becuase of the test pipes?

 

I dropped off my car today to get a custom true dual 3" exhaust done on our DSport G35 project car.

Exhaust Setup:
-2 X 3" Apexi N-1 Turbo Mufflers
-2 X 3" Magnaflow 14" long Resonators
-Altered Atmosphere Y-Pipes
-3" Stainless Piping

Engine Setup:
-Built Motor
-Tomei 268 cams
-DC Headers
-Vortech V2 T-Trim with custom piping and intercooler
-15psi Pulley, custom cog setup

 

Man that sounds pretty sweet....what kinda power are you seeing from that engine?

 

You just put the o2's on the test pipes where they would go on the cats. Car will run a little leaner but once you tune it doesnt matter anyways. Plus you want to run a wideband o2. AEM or Innovate but AEM starts to walk after a while and doesnt stay 100% calibrated.

 

Thanks, we're looking for around 6-700hp.

 

Thanks for all your help guys i have decided to go with the Fast Intentions Intimidator exhaust and resonated test pipes.... There is a group buy going on right now if your interested take a look....
