Also interesed to know when HR pipes will be available.

I can provide tests from a Australian dyno if you like. Would be a comparison of stock cats to ART pipes...

Any updates on the HR model? I am one out of the hundreds out there who is very interested. Please update us on the HR model development. Thanks!

I'm sorry if this in the thread, but have these been back to back tested against plain non resonated test pipes yet?

Hydrazine

iTrader: (53)

People have it for testing, we just have to wait for the results.

How will this sound with an unresonated XYZ/shockwave (with the resonator deleted from the midpipe, what you did for a member a while back) setup? It should be loud & deep w/o a lot of the rasp? Will a setup like this drone a lot? Thanks.



I would love to test these on my HR

has anyone bought these yet who is supercharged and already had test pipes or high flow cats even? or anyone F/I tested these yet?

I havn't tried it on the non-resonated XYZ pipe but I seriously doubt it will rasp.
Drone should be attenuated too.

If im tuned for a regular exhaust set up(tanabe + y-pipe+ HFC's and I swap out to ART pipes, can I get away with it without affecting a/f ratio's that much?

if u are tuned for ur current setup then i would see no point in changing to the art pipes if u are not gonna re-tune for them..will probably not benefit u any without tuning for them..

... except I was tuned for my Stillen HFCs and saw a gain of 9whp.

The AFR leaned out a bit, but not too much - nothing to worry about. (went from high 12's & low 13's to mid-low 13's.).

and ur happy with that? i would not be happy to spend 700 dollars and get gains i could get with test pipes for much less..I understand u dyno'd and got the discount and all that but in this case he is not going to be dyno'ing for the discount as it seems since he wont be getting a tune as he said so imo not worth it if u are not gonna tune for it ...


dont get me wrong these are proven to be a great product, they are just pricey and i am waiting to see if they are really any better as far as gains than test pipes

That is my concern on gains without tune and a/f ratio. Ive dropped alot of money recently and would need to replenish before re-tune.

I noticed how you made gains untuned. Now how much more might you have gained with the added tune for ART pipes?

Dude, I don't think you get what he's saying. Look at it this way: if he installed his ART Pipes over a stock setup, he'd have gained close to 20WHP. HFCs net around 8-10WHP, untuned. And replacing HFCs that were tuned to the car to gain another 9WHP (on old tune) is insane. As all the dynos show so far, ARTs gain 10WHP over test pipes or HFCs. So over OEM, it'll be around 20WHP.

I'm ordering my ART Pipes very shortly. I have most of the bolt ons, including Ultimate Racing HFCs and with the tune now, my car pulls beastly. I seriously cannot imagine how much sicker it's going to feel with the ART Pipes. Nevermind when I actually get the ECU retuned for them.

I totally understand what he is saying and im still not sold on them as i have not seen a comparison to test pipes..where have u seen a comparison from test pipes to art pipes? maybe i missed it somewhere

Yes, if you already have a good tune with all your other mods and then install the ART pipes, it won't affect the A/F all that much.

Of course it would be better with a new tune, but it is not necessary if your engine is already running healthy.

Its when your car is already running lean that adding breather mods can show less gains.

I've seen many times how a well tuned engine Vs a poorly tuned take to mods. Its predominantly the lean engines that don't do well with NA mods.

I don't agree if his tune is currently good.
