LOUDEST C8 cat back?
 

I am wanting to get THE loudest NPP cat back exhaust for my new C8. I do not care about drone while cruising in fact the louder the better. Who makes the loudest over all NPP cat back for the C8? Thanks

Check out this vid. This is my C8 at about the 4:25 mark. I don't know if it is the loudest but I love the sound. I barely rev it but you can tell that at even rolling speed, the exhaust is def there. It is an MBRP exhaust.

Do you need to retain NPP?

Not to hijack the thread , but an even better question - What is the most exotic and sexy sounding exhaust ?

Yes. Keeping NPP to me is very important although I always keep my exhausts in track mode.

After a lengthy research and You Tube clips I think I have narrowed it down to either the Billy Boat fusion as on my GS or the Corsa Extreme. Very impressed with the Corsa Extreme so far. The Lingenfelter You Tube clip comparison with OEM and the Corsa extreme is very impressive! Any C8 owners with the Corsa Extreme or B&B fusion and their experience would be helpful as well.

So far my Paragon has way more exotic sound to it than i expected and just what I wanted. I have the track version.

This seems to be the consensus from those who own it. Did you go with the touring or track version?

The loudest valved exhaust I have personally heard is the Soul Valved Exhaust. This will retain NPP but still wake the dead the the valves are open.

I can shoot over info and pricing on it if you would like!

Thanks

Which MBRP exhaust do you have, that sounds amazing !!

I assume you’re asking me as I am the one who posted the video clip. It is just listed as the 3 inch cat back quad. The model number is S70403CF.

I can verify the MBRP is nicely loud:) Had it installed at Corvettes @ Carlisle. It now sounds properly Corvette. On the trip back South, didn't notice any drone in either V8 or V4 mode. Mode switches are much more noticeable than with stock exhaust, but it wasn't annoying (to me). Was a little surprised to have a couple of 18 wheelers make known they wanted to hear a rev during the trip. Never happened before.

A couple of sound clips of the MBRP from today.
Have a slightly longer one, but it exceeds the file size limit:(

Longer exhaust clip on Youtube.

Here is another vid. Of course, video sounds do no justice to hearing it live.

I have the Topspeed Pro1 Titanium Xpipe and it’s super loud with an exotic tinny tone. With the 2M cats along with the Topspeed Pro1 not having mufflers, I even get small flames from time to time

Bump. Interested in the Corsa Xtreme even though itll delete NPP that comes with my z51 car. Anyone experience issues with droning on any of these (especially the corsa)?

They have variants that will keep the NPP (if you want) we have them in stock. No drone with valves closed.

Cross plane will never sound exotic. For loud go straight pipe after the cats or regular exhaust with cat bypass. For incredible sound cat bypass with straight pipes. Had a Ferrari 575(v12) straight pipes after cats. Glorious sound. Viper GTS. No cats,straight pipe exhaust. When on it could be heard 1\2 mile away. Either way no problem idling past cops or quiet zones
