lol

how ignorant.

 

yah that is ignorant.... about my comment originally saying it would not make power/ lose power... i was referring to his 3" exhaust with custom mufflers on his car N/A stock as is .... i dont think it would make power.

 

that was na before the SC

 

Yeah...I was assuming an EMS...regardless, better safe than sorry. Buy/install all the bolt ons and get 'er tuned accordingly. Didn't mean to rock the boat.

As for my ignorant comment about exhaust on an NA application...show me a dyno with any significant gains from exhaust on an NA application and I'll eat my words.

Haha, Justin is right. Please do some research before you make such a broad statement. This thread is full of dynos with people making pretty good power from aftermarket exhausts, he doesn't need to post it for you. Take a look at the NA tuning forum pls. Thanks

 

OK, without getting into the middle of this debate, I've got to ask you to post a link to the "NA tuning forum," because if it is here on S2kI I have managed to totally overlook it for over two years. Did I miss something, or are you thinking of some forum other than S2kI?

I also checked this thread, as per your request, and I can't find any of the dynos you claim it is full of. Since the hread is only two pages long I have a hard time believing that I'm overlooking them, so it looks *to me* like you're making this stuff up as you go along. If not, please quote the posts in this thread that show the dynos you're talking about. Also, if you don't mind, how about posting a link to the S2kI NA tuning forum.

 

The dynos they're talking about do show some gain. However, I havent seen a single legit dyno (ie. dyno'd on the same day, back to back, same dyno, stock vs stock+aftermarket exhaust).

I dont doubt that single exhausts will gain you power, but i think its closer to <5rwhp and ~15 rwhp is more than an overinflated number.

 

He's talking about the JDM tuning forum, specifically the "I want 230 rwhp" thread. Link to it in my sig, I made a little animated gif for it.

There is an owner making 227 on a mustang dyno, with 70mm exhaust, hondata IMG, and vafc.

There are others making 230, or damn near close to it on dynojets. Where is this power coming from? The exhaust. 70mm singles make great power, and with simple tuning, you're up over 20+ hp from stock.

I don't want to post dynos; I don't keep them laying around so I can prove to ignorant people that make broad statements that they're incorrect. I just think NA tuning gets a bad rap because everyone has seen aftermarket stuff NOT work for so many years, when the parts that DO work have only come out in the past year and a half or so. They're so far removed from reality, living back in 2002 when all that was available was Comptech exhaust and other crap like that (no offense to people who own it, I'm sure you have your reasons, but power mustn't be one of them).

I just returned to stock exhaust and header after having J's header and T1R 70mm and the difference is unbelieveable. Yes, there are 70 more pounds added, but the car just doesn't pull like it did. This isn't just butt dyno or audible difference, the car feels like it's literally "choking" when I VTEC. The low end pulls much harder now, I definitely feel a little more torque up to 3500 or so, but after that, the midrange and high end feels like it's trying to breath through one nostril when you have a cold. I've probably lost over 20 horses, as I've set my VAFC2 back to stock as well. That is a big difference, and all that's left in my car are the 4.77s.

 

Nice, you come charging in here calling everyone ignorant and that we're all living in 2002? You're on your way to being well recieved, keep it up.

Either way, you're in the FI forums where people actually have legitimate dynos that show a 70-100 rwhp gain and loads of videos of FI vs stock to back it up.

You're saying you "probably" lost 20 rwhp... sorry, i dont trust your butt dyno nor your theoretical numbers. I'm sure a lot of your power loss could be attributed to less intake/exhaust noise, but noise doesnt translate into power.

I've seen some pretty goofy looking dyno graphs posted in the JDM forums. Why is it that valid dynos are so abundant in the FI forums and that anyone would be hardpressed to find a dyno graph that was done under controlled conditions to show the delta?
