Electric cutouts vs muffler delete
I recently bought a new LT1 Camaro and have found myself already looking for an exhaust, but I am not willing to spend $1000-$1500 just yet. I had been considering doing the muffler delete, but this car is my daily and I do not want to wake up the whole neighborhood as I leave for work early in the morning. This is where I started looking into electric cutouts. Will the use of cutouts cause any harm to the engine due to a change in back pressure (potential of leaning out)? Will a tune be necessary with the muffler delete or cutouts? I believe with the cutouts being back near the muffler that they will not make the O2 sensors adjust the air fuel mixture, but I certainly want to confirm this.

honestly i'd save up and get the exhaust if you dont do a delete. the troubles you'll get might cause more headache. only my thoughts.

As long as you put the cutouts downstream past the cats I can't see how that would be any different than a no muffler setup and far as how the ecu performs. Each to their own though but for me straight pipes and/or cutouts just sound like an old clapped out truck with rusted out mufflers - especially at idle. Now if you go cam and headers then cutouts are sweet!

I've been running cutouts right before the muffler for years. It won't do anything to the engine. I wouldn't do a muffler delete, it sounds unrefined.
Cutouts sound better because part of the sound still passes through the muffler and gets filtered making them sound deeper. Alot of camaro people like the way mine sounds especially that I paid $200 for everything and they paid $1500 for the same basic sound, sometimes even more raspy. |

Save your money for a good cat back. Muffler deletes sound like a garbage truck. Pure ass. Your Camaro deserves way better.

From the videos I’ve heard, the muffler delete on these cars doesn’t sound just awful like most vehicles, but granted that is a video and it’s hard to judge accurately. I am more of a fan of the cutouts just for the reason i can keep it quite until I’m out on the Highway. I plan on doing a full exhaust once I am done using this car as a daily in a few years, so that is also part of my hesitation on just buying an axle back. QuickTime performance posted a video (https://youtu.be/z3xShlPxffc) of their electric cutouts and I think they give the car a pretty good sound that is loud on demand, but I was just curious if for some odd reason this would require a new tune, thus voiding my warranty.

I went through the same debate with my 1SS that lacked NPP
Decided against the cutouts when I didn't want to deal with wiring a switch and had heard it can rattle over time Went with the stock NPP with the valves constantly opened (lucked out getting a used rear diffuser locally) so all in cost me $200 I did run the car after I cut off my non-NPP muffler - hated the sound (just the opinions of my teenage son and I) Once we got the NPP muffler on, it sounded awesome... just enough crackle and pop and noise level for us.... My fiancé hated it to which I replied - "But it was a great father son project" LOL |

There's a rear diffuser on Ebay right now - though it must be a mistake since shipping is less than $8 |

If that is what you really want to do just cut the rear valence out for the quad tips. Otherwise a muffler delete is the way to go. Everyone that says they sound like crap on this car is just trying to justify their $1500+ exhausts. Cutouts would be the best of both worlds.
