Gintani Downpipes Installed

[kitw]

How is the stankiness? I'd guess with the stock secondary cats still in place, it wouldn't be horrid... sort of like the Akrapovic Evolution on the E90, stinky when you start it but fine after it warms up.

I know we did not turn off the CEL in my flash. The purpose was to see if the CEL comes on. Gintani does something different with the DPs, They do it on the M5/m6 and M3. So far so good.

I honestly can't smell a difference. I'm running Catless DPs and everything else is stock. (muffler,pipes, etc)

Turbo motors generally burn cleaner right?

I'm guessing it didn't provide much of a power boost on a stockish flash as they obviously dyno'd it after the install. If it had, that would have been part of the marketing ploy already. Too bad, still would be good data to see.

My thought. Possibly a loss in HP due to loss in back pressure.

+1. Amazing to me they released a product which, according to them, they never tested on a dyno.

Going in for a dyno in the morning. It was 630 PM on a Friday, with the weather being over 90 degrees in Van Nuys. Makes no sense to give everyone crappy numbers when the stock dyno was in the morning, nice cool air.

Nice, Josh! Good talking to you last night!

I know the secret... There is a metal potpourri canister that fools the ECU.

kidding, although some people on these boards will say anything. Kind of like the below posts

Highly doubt it. I guess you don't have much experience with turbocharged engines or catalytic converters. lol

Thanks, Josh. So many naysayers on these forums.

Not naysaying. As he's stated, they did dyno it and it didn't do what they wanted, which they chalked up to dyno conditions. I look forward to the results in similar conditions and hope they will post them up regardless of the outcome.

Back pressure is an enemy for a turbo charged motor you can only gain by reducing back pressure unlike an NA motor.

I am sure they will. We all know that regardless of the outcome, it will still be a positive change.

Just keep in mind that if you were a company, you would do the same thing. Why? Because a hot car in a hot region with crappy 91 octane is not going to produce anything like what a cooler state and 93 will produce. That being said, it should be expected that they want to publish the best possible deltas!

I think pointing out that they are selling a product that has never been so much as tested on a dyno is hardly out of line.

It wasn't out of line, just CC'd you for saying +1 on the misinformed post. Your point, while most can understand where you're coming from, is plausible. Im going to play devil's advocate though and ask... why do they need to dyno test it? It's literally pieces of metal that are guaranteed to fit and will make more power than stock. If you want something now, then you can purchase it. If not, then don't! lol. I just think whether or not they tested it is negligible at this point.

If its such a simple piece that a dyno isn't required I assume you can just look at the pipe and tell me how much more HP will it make? 2hp? 5hp? 20hp?

For this pricepoint I would expect at least some optimization/testing.

A dyno is never required. Doesnt mean it will or wont work. You can be a smartass, but the fact remains that if you're getting rid of primary cats, you're going to gain power. Your argument is literally worthless even though your thoughts aren't. I think you make a good point, but you quickly jumped to conclusions on whether or not they tested or did flow analysis, or anything for that matter. Just saying.

As far as the pricepoint, *I AM NOT SPEAKING ON BEHALF OF GINTANI*, but all I can say is: Simple Economics....supply and demand.

ER will be coming out with theirs in the next week or so and I know a couple other companies who are currently working on theirs as well.

The most important part of this thread I got away with was... Gintani says they refuse to release a piggyback! If they can legitimately crack this ECU, I will definitely hold out for it & avoid the JB4 until Gintani cracks it..

[Black Gold]

So , i see you did a quick dyno pull, what were the results?

Edit : and bullsh*t a dyno isn't required. For 1300 dollars I want a dyno, and so does everyone else. Products need to prove themselves, bottom line. No dyno, no consideration

This would be amazing but seems unlikely that Gintani cracked it.

With the e9x no tuner actually cracks the ECU. They all get the software and cable from the same source and just put their own branding on it.

In fact several (all?) of the tunes for the e9x come from the same original source and are just tweaked by the various tuners (if at all).

From reading the OP's post, he has been running a Gintani beta tune when the downpipes were installed. I don't think they want to release dynos right now with an unfinished tune. OP said they didn't have time to reload the stock map. I am sure we will get a dyno soon, with the stock tune back on the car.
