ACE 350 Header Hiss

[mistople]

Stock front pipe is usually the way to go if you don't want rasp/excessive volume.

I run A350 -> Stock FP -> Perrin 2.5" and it's a great balance of volume and rasp. I had a JDL UQ FP fitted for a while but I never really liked the sound.

shit i just ordered that because the PLM was too loud

I also ran Ace + stock FP + Touring86.

Enough volume to hear on throttle, completely inaudible on highway cruise.

I think it's the 4-2-1 desgin. My JDL has a low RPM sound that is kinda tinny or rasp. More pernounced next to cars or walls.

Rather thinner tube walls and no stock heat-shield on top, much more probable then specific header design. Then again usage of thicker wall tubes will reduce clearance and up the weight (and price, due costlier materials and more work with welding), many won't like weight increase to change a bit tone/rasp.

My wife didn't like the smell of a cat less set up and even with the Touring86 catback it was a bit loud for my taste so I dropped the Ace front pipe and put the stock pipe with the cat back on. Surprisingly it sounded way better and the exhaust leak noise disappeared.

No idea why

How was the volume with the frontpipe? Thinking of going with that exact setup...I have an invidia N1 catback which I might leave on after putting on the headers just for shits and giggles to see how it sounds, after which I’m planning to replace it with either the Perrin 2.5” or the Touring86 you mentioned. I do like a little bit more volume to the car (as indicated by the fact that the first exhaust mod I bought was an N1) but also need it to be daily drivable which it definitely won’t be if I leave the N1 on.

I ran ace 250, hks double res fp, touring 86 cbe. Sounded great, barely noticeable over stock when cruising but comes to life on throttle.

Eventually hks double res fp cracked at weld, switched to stock FP with cat punched out, sounded a little different but still sounded good and same volume. Neither droned. Just good clean exhaust.

Sounds good! I was looking at that HKS FP earlier, when I was planning to go JDL UEL’s w my N1, but I’m not planning to go the FI route (car’s only a year old) anytime soon, so I just wanna maximize my stage II gains, which is how I found out about the ACE header. Your description basically sums up what I want the car to be like...as much as I LOVE that deep rumble you get at idle w UEL and N1 paired, the performance results just aren’t the same :/

Perrin 2.5 resonated is up your alley. Csg touring will be to quiet imo for you

Interesting, though I have zero experience with FP's other than stock, what you say is quite contrary to most stuff I've read. Though I do believe it would be well toned and not too loud, everyone tends to say that once both cats are out, it's loud. I believe many people adjust or don't mind the louder noise and think it to be barely noticeable over stock.

I run the ACE 350 + OP, stock FP, and Touring86 - and this setup is already on the limit of being a bit loud. It's certainly quiet as people say, but that's quiet in comparison to most other aftermarket exhausts. Startup at 2k RPM is plenty of noise and any good bit of throttle at any RPM brings out the sound.

Like I said, I guess it's more of a personal preference to what you believe to be loud or quiet. For me, I can't imagine going cat-less FP and not thinking it's a bit too loud for my taste. But I did consider that if I were to ever get one, it would be the dual resonated one to help control the sound and drone to the best ability.

Perceived volume is definitely subjective.

Most people running no cats are not running Touring86 which is one of if not the quietest aftermarket exhausts.

You can tune out loud cold starts.

Volume was more based on throttle input than rpm specifically.

When cruising even at 3k rpm it was pretty quiet. Louder than stock but not by much. When giving it throttle however it really woke up and thats when the volume came out but still tame vs a lot of other aftermarket setups.

Have the cold start removed from your tune, and it'll eliminate the loud 2k rpm starts. That's loud even on a completely stock car!

I was under the impression that "removing the cold start" referred to simply lowering the RPM's the car revs up to on startup? Mine was shooting up from 2.5-3k on freezing days so I had my tuner take it down to about 2k. Is this not what you are referring to? If not, is there any downsides to removing the cold start? Is it not there for a reason?

That's.... sort of what I'm referring to but not really.

It's there to warm up the catalytic converter. If you don't have one in your header (which the A350 doesn't), it does nothing but make a lot of noise.
