See you later secondaries!

So after starting a few exhaust threads over the past months, I've decided to delete my secondaries after hearing another member's video(iuhutch). That video had a catless downpipe and hpf exhaust with no secondaries and it sounded wicked!

My route is a bms downpipe, secondaries deleted with corsa mufflers because I would love more sound! Of course, the corsa mufflers are supposed to eliminate drone and surprisingly thus far, have done a great job!

Now we will all get to see if the corsas can handle catless with minimal drone. I am picking up tonight and will share results. If you search on YouTube, I have revving videos already with downpipe only and downpipe-corsa combo. Another will be up when I get a chance. Wish me luck-want the best sounding n55 out there haha!

Oh, and if I can't take the noise, no biggie..I will either add stock mufflers or put vibrants in the piping!

Not as loud or aggressive as I would have imagined.

Yea the secondaries and mufflers do a good job to keep it semi quiet. Under full throttle it was nice.

I absolutely love it. No way I'd ever go back. There are literally zero drawbacks to me. A lot of people complain about it shifting too early in D but it adapts and it's waaaaay smoother than stock

Ok, have the car back and it sounds awesome. Very mean, throaty, deep. These corsa mufflers must be magic because there is no discernible difference on highway cruising- I'm very impressed.
Full throttle though, it does sound incredible.
