How much power to gain/lose?
Current exhaust setup: Tomei UEL/Overpipe, Stock Front Pipe, N1 catback
Potential exhaust additions: Nvidia catted front pipe - what will I gain? Nvidia q300 - will I lose anything? This will be run with the v3 Vortech setup, tuned with OFT. I would like my exhaust to be a little more quiet, but don't want to lose power. I am guessing the front pipe will actually make it louder, but will it add power? |

nothing noticeable. you already got your best gains with the header, especially if you have a tune with it.

Not much gains from a catback honestly... Better to go high flow cat with q300 catback for quieter exhaust without sacrificing anything.

If you have to ask this please do not put a blower on your car. Only bad things will come of it when you run into issues down the road.

I do appreciate your concern, since you are assimilating asking what you would consider an obvious question, with an inability to ‘fix’ what is surely going to be a kit that blows my car. I will be sure to skip over any posts by you, in the future. |

To answer your question: Your catback will have the biggest impact on the sound. The front pipe going from OEM to catless hardly changed the sound (OEM headers at the time) at all with a TRD catback in my experience so if you keep a cat there I wager to say it will sound basically the same everything else equal. The midipe with a cat in it still will not net you any real gains. The good news is your catback will not gain/lose (provided its decent) any measurable HP numbers. In conclusion save you money with the midpip unless you going for 400+hp where you truly need more flow (at what point you should be catless anyways) and pick the catback you like best. |

Before escalade more, here's the thing. Exhaust setup isn't just simple gain or loose hp. Catted front pipe won't gain much hp to began with & Q300 catback won't loose hp anyways. Catback is mostly for driver's ear than anything else (maybe weight fact).
Tbh don't waste your money on front pipe or OFT & get EcuTek and get actual dyno tune. Current exhaust setup is good enough. |
