Mk7 Exhaust Tech. How to get the sound you want.

[E.TMK7R]

Hello Jake and crew,

I’m writing in this thread Incase anyone else has a similar question or situation as me. I have a 2016R stg 2 custom tuned with apr catted/res DP & stock muffler. My difficult goal is weight reduction and least amount of noise. I know crazy! My idea is to get rid of stock muffler and throw in 1 or 2 17950s(or something else)starting from where APR DP ends with a turn down pipe at the end of the 17950.
not sure if anyone has done this before or would make any suggestions for least amount of weight with least amount of noise as possible with a APR catted/res DP? where would I want to place the resonator(s)?

Keep the oem resonator and do muffler delete.

You’d want a 17950 and a Borla Pro XS.

Two resonators isn’t any better than one, they do the same job.

Keep the oem resonator and do muffler delete.

No, don’t do that.

My OEM resonator is already off and not coming back so wouldn’t be able to. Again trying as much weight reduction as possible too.

No, don’t do that.

Thanks Jake!!! is the Borla pro XS could be bought on Amazon I’m guessing? Not referring to a complete exhaust right?
Then the turndown pipe behind the borla pro xs?
Lastly any thoughts on MBRP pro series muffler delete system?

I’d buy it from a reputable source like Summit Racing.

No comment on that. I’m a fabricator and don’t endorse junk

My current setup is drone free on stage 2 with oem resonator and muffer delete, while i have some sound deadenings in the boot floor, under rear seat and rear wheel arch.

Adding a data point to go with this thread.

I've had the UR catted/resonated DP with stock cat back for about 25k miles. The sound is no doubt very close to stock and no drone. The down side is that UR uses a flange system on their exhaust systems which boxes you in to their products unless you go to a shop of course. The other downside is that the rear resonator flange is extremely close to the tunnel brace and hits and vibrates. A few folks have reported this. To eliminate the rattle and the redundant resonators I had both replaced with a 17950.

The sound difference is almost not noticeable. At the very least the sound is slightly "bigger" but not louder and no drone. I may end up doing the borla but I'm afraid it may be a little too loud for my taste.

Also to note the UR resonator has their branding but looks a lot like the Vibrant Ultra-quiet. Who knows?

Similar, but not a Vibrant UQ.

Here’s a pair I used on a Q50 3.7 last week

Purdy! I've had several Infiniti's over the years, but the sound generated from the VQs had always been...odd. Any sound vids from that?

Hell yeah!

Cheater, you started with a car who's engine sounds 100 times better than ours.

Ive got Mk7s dialed in too.

99% of people just learn the Honda/diesel lessons the hard way and blame the Gen3 TSI.

Jake, I went with your suggestion and swapped the CTS CBE for the CSS muffler. I've been reading that res delete would deepen the tone and some of the videos I've seen would suggest the same. However, I'm not trying to spend $150+ on a pipe and 2 clamps to accomplish that. Any recommendations? Do you sell a res delete kit?
