Thoughts on exhaust.

[GotGrip?]

Saw these tonight and figured they would be worth a mention. Anyone dealt with anything like this? Figured cuts would gain performance waited without spending 1k on a full exhaust. Granted it will be loud as ****, but at least its free flowing when I get on it.

Well, I think those who know what I've done to my exhaust know how I feel about free flowing, open exhaust, LOL. Loud for sure, but I think there's gains to be made in that area. I say go for it, they seem easy enough to remove and revert should you find it doesn't suit you.

My question is, how do these ones work? I was trying to see what they meant by automatic. Are they boost/vacuum referenced? Is that what is connected to that actuator?

It's like a waste gate, just run a vacuum line and when it seeing "x" boost it will open

I had ideas of doing this way back. Boost activated and I found a video of someone claiming power increase on a dyno. I've seen a set of welded ones with an x pipe and it was a work of art...pricey too. Then I've seen some that look like balls hanging lol and too low to the ground. So a proper mounting is definitely something to consider.

Having the exhaust go right from turbos to stock cats to behind the front wheel and it still wasn't loud. Unless you have test pipes it's not a loud car.

The gains will be extremely minimal and at the end of the day - it's still a 6-banger! This car will never sound good! I've spent too much time and money with mine that I regret!

Oh it's very easy to make these sound good, it's just harder if you want pipe all the way back. I've got a Borla pro-xs on it now though and it sounds good for a quieter exhaust.

I had electric cutouts for a minute, if you have stock cats it's not too loud but it's droney as **** at cruising speed. I've wanted to try the boost activated ones for a couple years but never got around to it.

To each their own as it goes - I'm just use to the very deep aggressive V8 rumble or even a V10 like Audi or Lambo. Any 4 or 6 knocker sounds so raspy and drony - it's just physics, I can't stand it. Don't get me wrong, I've heard some OK ones and mine is at the point is "decent," but just today an older (the most recent version, 2000-something) of the Pontiac GTO pulled up next to me and holy shit that sounded amazing!

Yeah I can't stand any rasp at all, it has to be deep which is why I never cheap out on things like this. Its also the entire reason I kept the stock cats lol.

Unless it's in a Maserati.
