+1. Watching closely.

I really want this to work out for the OP, I hope it doesn't go on too much longer. Good Luck.... I'm personally finished with the idea of getting a BB exhaust sys. It took Appereta over a month to get the cat deletes and the midpipes. Then he had to wait additional time for the cans since they were shipped separately. Now, add the fact that they sent him a pair of redesigned cans that have issues. If I read right it was on 9/12 when Appereta contacted them and BB said a new set of cans would be coming, I guess this will be over another month. |

I am kind of in the same boat, but..... I am still waiting to see if the new/old muffler design has any reasonable sound change... I cant believe no one makes and exhaust that has no drone and npp valves that make an actual difference..... |

NPP makes almost no difference at idle and when cruising. It makes a small but noticeable difference when driving hard and high revs. Last edited by Aperretta; 09-23-2018 at 08:02 PM. |

If due date was achieved and mufflers weren't defective, I would point attention to the sound being really nice. I could appreciate a little more volume and growl out of the system, but it does sound good. The NPP valves and drone would be livable. Just trying to give good feedback where it is due. However, 50 business days and no good mufflers is a big problem.

Customer Experience/Service and Quality Control should be their top priority. When there's an issue, they should put the other manufacturing on halt and move you to the top of the list to make things right. If it were me, I would give them until tomorrow (maybe the end of the week if you're feeling nice) and tell them to take the system back if it's not met. If they give you a hard time, go for the dispute route with your CC company. |

Sounds good, but they really should have gotten rid of the check engine light.

I see a lot of threads about exhaust, what h.p. gains can be made with headers & cat back exhaust on a 376ci engine?

Don’t expect much from just exhaust. I think I’ve seen others post around 5hp and 10 tq. I feel like my car is slightly more responsive than stock and may have a tad more power but it’s not enough to know if I’m just associating more noise with more performance.

I think Stock NPP sounds similar just not as loud. Extremely raspy. Last edited by MackSteelPrivateEye; 09-25-2018 at 10:48 AM. Reason: dd |

I think Flowmasters offer the best sound and Value. Less rasp.
