MPE / Akra exhaust with catless DP's

[nash_86]

I've already pulled the trigger on buying VRSF catless DP's.

Do I still need to get MPE / Akra to improve the mediocre stock exhaust sound or will the DP's suffice?

Start with DP’s, then, resonator delete, then decide

Whatever you do - keep at least 1 set of cats in your system or you're in for rasp city

don't fall for spending too much on a rear muffler box, there's a lot of sound difference in the centre section.

I would recommend replacing the centre resonator with two after-market resonators and a H-Pipe to balance the sound.

I installed VRSF DP's a while back - and the volume increased significantly. I have a stock ZCP setup. Invest in a exhaust valve controller and keep the valves open - that should keep you happy.
