Exhaust Setup n54

nic_hender · 09-15-2018, 05:49 PM

HI,

Okay I am in a situation, Currently, I have only a muffler delete(done by past owner) and it already idles at 85-95 dB, does that sound right?
I have catless downpipes that came through the mail recently and they are going to be installed on Tuesday. I was wondering should I add Borla XR-1 mufflers or resonators like vibrant 1792. I have heard that resonators don't do much and I want to keep a loud sound but I don't want it to feel like my ears are bleeding. Any Suggestions?

Update

Catless + Muffler Delete is louder but less drony than just muffler delete. On the highway at cruise control at 76 there is no drone what so ever, even with music off. Past that it starts to become very boomy and drony.

Resonators will help that

I'm currently running the VRSF 3.5 inch cat back with downpipes and really enjoy it. Not too obnoxious or droney at lighter throttle applications but definitely opens up when you get on it up past 3K. Also from the sites I've seen it's about half the price of the borla. Just my opinion though others might not like it as much

Do you have a gas smell even with the after market catback? I am good with the smell because that is okay but I was just wondering

No smell with stock downpipes.

I have no cats and can only smell If standing behind car or random slight smell If parked with windows open
