Resonator Delete vs Cat Back

The price difference is obviously a lot different

I would try this for $300 and see what you think ... you can always order the more expensive system

Does resonator delete change anything on the butt dyno?

Go with a resonator delete or would a MagnaFlow cat back be worth the price tag? The exhaust on this thing sounds so good, it's hard to decide if a cat back is worth the cost like on most other vehicles. Would probably want to go MagnaFlow if I did. Debating.

Safe to assume no tuning requirement or issues with either route on this thing?

Is there really any benefit to this Mod? Is there a HP increase or ?

Benefit?? Yes, if you consider sound a benefit...which I believe most do! I would! There's a ~5 hp difference on the R that I have yet to find what it's solidly contributed to. The only difference it could be between the two cars is the wheels/tires and the (lack of) resonators on the R. But in my homework, I've yet to find any dyno data or anything on a non R car doing a before & after resonator job. Logic would dictate they wouldn't do this on the R if having the resonators added something beneficial to the power. For the life of me, based on what I know of things, I can't imagine removing the resonators would hurt anything at all power/performance wise; but that's why I asked the question I did about the butt dyno from guys that have done it.

I can more than understand the sound benefit, for me it’s just turning off the Sync system, open windows and place car in performance exhaust mode. I believe the R’s benifits are in its wheels. Lighter and able to transmit HP faster to ground. Been proven on time trials with and without the CF wheel package. But in CA, an exhaust system is part of it’s emission certification and any modify will be scrutinized by the Emission Police who can require you change it back. The replacement x pipe requires a cut, not a bolt on. Don’t need to invalidate any Cert on the car before it’s warranty expires. In CA that’s up to 80K on many components.
