Invidia Q300... My intake is louder than exhaust lol

I just ordered a Q300 and the catted Invidia front pipe. Downgrading from my 3" exhaust because the JDL UEL brings out the vibrations inside and some drone. My mirrors all shake too. Might shelve the exhaust for turbo later.

Definitely want to tame down the catless JDL because I love the header.

Out if every exhaust I've heard on these cars in person the q300 was quietest for sure.

Yeah, I think as more headers arrive to the market, especially the catless ones, people (like me) are quickly figuring out how loud these thin walled headers really make the rest of the system. The Q300 with the titanium tips looks pretty good on the ultramarine color so I'm looking forward to it.

I don't mind a loud exhaust, but when it's so loud on the interior and makes your head almost shake and give you a headache, it's time to swap. First time this has ever happened to me. The Q300 will be plenty loud with an overpipe, catted invidia front pipe, and the Q300 catback.

q300 i have it trust me very quiet put once you go catless front pipe its pretty great sound

[wparsons]

My Perrin 2.5" resonated is pretty quiet. With the windows down it's a bit boomy around 2000rpm, but at 3000rpm+ it's not loud at all, and with the windows up it's very quiet.

I'm on the stock header, but 2.5" catted front pipe.

Did you plug/remove the noise pipe?

The car was terrible inside the cabin after i added a catback (lol magna flow) without plugging the noise pipe under the floor mat.

Q300

Invidia really makes it channel the sound to the back of the car.

You won't hear it inside the cabin really, and there is no drone.

q300 is quiet. with headers its the perfect volume

It is also heavier than the stock exhaust, which makes it a non-starter, IMO. Still waiting to see how the Tomei 60S sounds with the silencer in. I think it'll still be too loud.

Always a trade off but ya you're right worth mentioning for those with weight concerns I suppose, good point. Me I wouldn't worry about it though cause enjoying your car while driving in every way is worth more to me then having annoyances that take from the experience.

it's one of the most quiet exhaust system and has zero drone

Is it still mild with an upgrade catted front pipe?

I've always had my eyes on the Perrin resonated but now I'm torn between that and a Q300, I kinda like the uniqueness of the titanium burned tips but not sure how it'll look on a black car.

You also need to factor in the pipe size. The Perrin is 2.5", the Invidia is 60mm which equates to 2.36". Won't see much of a difference either way. I went with the Titanium tips because I have an Ultramarine and I take my car to local shows. Q300 is a bit heavier though so if weight is a big factor for you, the Perrin may sway your decision.
