Question for Timbo
Hey Timbo,
I'm guessing you kept the stock exhaust cans, yes?
How different does the exhaust sound now that you have the sport cats. Any way we can hear your cars exhaust sound, maybe a video sound clip please.
I am interested in making my car louder if it's feasible.

Louder is achievable with several different options. To my ear, though, none of them sound better than (or even as good as) the OEM set-up.

I agree .....
I personally don't like the aftermarket exhaust sounds. I think the original exhaust sound's best. I just want the OEM exhaust sound to be louder, if possible.

Pretty sold on these 200 cell cats already. A couple of questions im hoping Stuart can help with:
I would love to ultimately keep the stock x pipe and muffler and just have higher performance and an amplified stock exhaust sound (as others have also wished for) from these high flow cats. Adding these cats will improve the performance and increase the sound, but does anyone know at what point the stock muffler becomes a bottle neck on the whole system (with valves opened of course)?
i haven't seen the internal workings of the stock R muffler, but what kind of big horsepower numbers have these v8 f-types achieved with all the typical upgrades but keeping the stock mufflers?
thanks.

At some point it might start to show some statistically significant restriction but I think you'd need upper and lower pulley and tune and possibly a 100 shot or a larger blower to start seeing that.
As exhaust gases travel further and further from the engine, they cool rapidly. A lot of heat is dissipated through the exhaust system and into the environment. With cooling comes a corresponding decrease in pressure.
Remember Bernoulli's law states that as fluid moves from higher pressure to lower pressure areas, the speed will increase. So as the gases dissipate heat along the length of the exhaust system they decrease pressure/volume and accelerate.
So by the time the rear muffler area is reached, pressure restriction is far less influential than it is for example in the header collector.

The stock muffler hasn't proven to be a bottleneck at all. Bear in mind the SVR is pushing 570ish, and we are running 650 with crank pulley & tune, all through stock exhaust systems.

This is for my SVR. I have the 200 cell pipes now, but I want it to be a little less raspy, especially when cold.

I have a set of ceramic coated, RESONATED, 200 cell downpipes being made by Velocity to hopefully achieve a louder yet non raspy sound. RESONATED = 12", free flowing resonator added to each pipe after the cat.

Hello,
Would it be possible for VelocityAP to provide just straight downpipes, without catalysts? Also, will there have to be another ECU map compared to the one VelocityAP has developed for the 200-cell cats? Any other non-sound related things to consider? Will the power and torque figures be the same or different compared to the 200-cell cats?
Thanks,
