(Invidia N2 + Catless UEL) vs (Tanabe Concept G + Catless UEL) which has less drone?
 

I currently have the Invidia N2 exhaust paired with Tomei UEL headers. The N2 exhaust by itself without headers drone a decent amount but it was nearly quiet levels of stock on the outside and the drone was very manageable. After Catless headers the volume on the outside is fairly loud, not Tomei loud but people notice you driving by but as a result the drone has become quite harsh at times especially at freeway speeds. I love the look of the single exits however they all tend to be notoriously loud and drony. Looked into the quietest single exit I know, the Tanabe Concept G, and was wondering if it may have less drone than my current setup. I want something that has less drone than my current setup but not completely lose the volume because otherwise I would just go with something like the CSG Touring 86. Does this sort of exhaust exist and is the Tanabe that exhaust? If not what could be a good compromise here regardless of dual or single exit in that case?

You probably have the worst combo for noise.

Few options

Perrin 2.5 Resonated
MXP SP
INVIDIA GEMINI (R400)
Q300

I’ve heard a ton about Perrin 2.5 resonated and a bit about the r400 but I’m curious to learn more about the MXP SP. Mind going in depth with that exhaust? How much quieter is it to my exhaust setup with the UEL headers volume wise as well as in terms of drone?

Here is how I would rank from quiet to loudest

And drone wise these would all have less drone?

Yes. Do you still have stock FP with cat and resonator?

I have the the stock fp and op, just the catback and Tomei UEL Catless headers. I plan on changing the fp and op in the future. For fp I’d do the Fujitsubo dual resonated as it is widely regarded as the quietest fp showing at most 1 dB increase in sound.
