Any discount if i get these and provide sound clips + dyno tests?

Dyno tests would be what gains these pipes would have over my F.I. HFC's though...
Of course.

DISCOUNT FOR DYNOS

Tony, what is the dia of these pipes 2, 2 1/2 or 3? I might pick up a set to compare against my RTPS along with your cat module.

Do you have pics of these installed?

My question is how would these setups compare in sound & performance?
I do realize I'll have to wait for dynos & sound clips but more explanation from you would be appreciated.

Thanks
The TDX will have an edge but they are pretty close for NA. If you plan to go FI, then get the TDX for sure.

Excellent . So these ART pipes will further reduce droning, make better power at lower rpm's than regular tp's, and might even quiet down the exhaust a bit? PM me how much it would cost please .

Nice. I'd be interested.
I'm just a tad bit worried on the clearance for install, not to mention since no flex pipe is offered, how the longevity of the pipes will last.

They do look great though.

They have a 2.25" inlet and a 2.5" outlet. No pics installed.

RTPS?

They show a large peak relative to test pipes because test pipes lose a lot at that point.

The dyno plots I like to use are A minus B plots. This method of plotting shows the deltas in VASTLY greater detail and clarity.

The traditional dyno plot may work for showing absolute peak values but they leave the viewer pulling out a ruler and pencil to figure out the deltas at various RPM's. And mod performance is important over the whole curve, not just at the power peaks.

I agree that area under the curve is what we're looking for but most people get caught up in "peak." Just glad that someone takes the time and patience.


PM a price & discount for independent dynos please

So the beauty in these is that it really improves low end power (torque) which would be lost with normal pipes.

I didnt realize that those extensions were for the O2 sensors til you posted up those pics. O2 sensors will still get a good reading there?

Tony, with the remote location like that would having a wideband bung welded in affect performance at all?

Tony, forgot to ask you this in the post above. Why is there some steel wool like material inside of the O2 bung?
