All of you guys bashing RPI are doing so comfortably hundreds and thousands of miles away. I'm sure someone local has seen this thread but yet no one will go. Free dyno and gas to get there, nothing to lose and you get to see what your car can do. I dont have a E9x yet but in a few months when my lease is up and this bash fest is still going on, I'll volunteer my car to silence all this nonsense. If they really were that scared that people would find out their exhaust doesn't perform would they really post up their address, offer to pay for gas and dyno ? Come on, common sense guys, people with things to hide dont openly welcome disbelievers.

If this is still goin on in the summer around June when I get back I'll go and get a free dyno and show everyone u can't get that much power just from an exhaust

If you think an exhaust ONLY on this car will make that much power (with nothing else), you're insane.

Their name is already out there, with other BMW models.

They make some big power with the M5. There customer M5's consistently put the smack down on other tuner M5's.

I dont think Tam's car has a tune. You can confirm with him. We dynoed his car in the morning, put the car on the lift, put the exhaust on and it went straight on the dyno right after.

Who wanted to show me up? Youre in CT, come out, Ill pay for your plane ticket. Yes, I called you out, now what do you have to lose?

We can do more dyno runs and I would love to show you how the stuff works and how/why certain systems make more power than others. Ill show you how our stuff is designed and why. Ill show you how we measure EGTs, EG pressure, velocity, etc. I'll show you how we datalog, dyno, test, log iats, etc. So, if you are someone who learned about this stuff from the forums or because a buddy of yours worked on cars, or maybe you worked on your own stuff and bolted on parts..................

So yeah, who wants to come out? The So Cal guys have no excuse. Its an open invitation. I'd like to know how this system does on other cars with other mods too.

Sorry, I didnt answer all the different comments. Some of the guys have no credibility at all so its a waste of time to even answer some of the comments.

Note: Do some research about our systems before you want to embarass yourself. We have had guys try from all different forums. Either way, lets do it!

Here is an example of a customers friend who didnt believe all he did was our exhaust and scoops. Other than that, his car was stock and you can hear him ask, "What'd you really do to the car?" in the video.

Guess you need to find out for sure that it doesn't have a tune. If it doesn't, then those are some impressive gains and I applaud you on doing some fine work... if the car does have a tune, you may need to change the tune you are whistling about making such gains with just an exhaust. Just my .02 cents

There was no tune when putting the car back on the dyno. Tam stood here watching me. Plus, I wouldnt have given him a free tune

What happens when changing the exhaust system like that is that the DME allows a lot more boost to be run. If you keep running it over and over, the top end power usually dies down....depending on the tune. We see a limp mode issues with piggyback or even poorly tuned DMEs because the so tuner either didnt know how to tune it correctly or the piggyback just cant account for all the adjustments being made by the ecu. Dont get me wrong, the piggybacks make power. Its just not the right way to do it. People do it because it makes power and its cheap. The DME software is really sophisticated so its constantly making adjustments that is in somewhat "fighting" the piggyback.

Like I said, lets get some cars here to do more testing and we can video all the sessions. Obviously, Tam is a shy little boy so he probably wont say much on here but the more witnesses we have, the better right?

One of the few smart posters out there.

Either way, I am DEAD serious about flying the guy out from CT. Ill buy the ticket and post his flight info on the board to see who really needs to be shut up. People dont really do research before opening their big mouths. Cheers!

so your going to fly someone out to use your shop car on the dyno?

to have anyone who is not a monkey believe you......any test needs to be done not on YOUR dyno and not on YOUR car.

I'll be in So Cal in 2 weeks. Can we dyno my AE exhaust first then get your exhaust on? I'd be curious to see the difference since AE claims 12 hp gain,in otherwords, gaining roughly 33 hp. Mods are in my profile, we can keep them on or take them off.

Sure no problem. Please contact me from the info on our website.

LOL sorry don't have time to see your shop car on your dyno, I'd much rather a third party test it. Since you're willing to spend so much money, i'd gladly let you ship me your exhaust and do back-to-back dyno testing vs. the exhaust I have. of course you'll have to pay for everything (including shipping when I ship your exhaust back for not making anywhere near the advertised gains ).

Fly me out there and shut me up. I still don't believe you. Obviously I can't bring my whip out there though...

by the way that Ferrari video isn't impressive at all.

Exactly, Lets see a 3rd party dyno for the TRUTH!

[cn555ic]

Somebody thats looking for a exhaust should take RPI up on it...I mean there are so many members in CALI, I can't seem to understand why anyone won't take advantage of it and see one and for all if its possible to gain that much power with just exhaust...If so I am buying one and getting rid of mine immediately.

call me, Ill fly you out here 562-630-5966. Its gonna be coach though. Not first class. Think Im joking?

[Bobble]

I'm in Cali and hell I'm so pissed at clients right now I would not mind taking a day off say Thursday. My car is box stock so dyno it won't prove anything except what their dyno's reads on a stock car, exaggerated or not. But I would be willing to listen to what they do and how they do it and post it up informally to allow everyone to see. If that works let me know so I can adjust my schedule accordingly.

[jpsimon]

I'm dumber than you thought because I want the testing to be done by a third party? You're really winning over lots of customers calling folks names!

But seriously, you ship the exhaust out and I'll do same-day back-to-back testing (dyno along with datalogs). Prove me wrong

If you can come out on Thursday that would be nice. That way we dont have to wait for the other guys. Anyone who wants to come can come. Just call me and schedule your appointment with Kathy. Bring a video camera too. Im not going to send monkey boy an exhaust esp since he is with a competing vendor. lol. Either way, lets video the session and anyone can come watch. I've been dynoing for 12 years so I dont really trust others. I used to do testing for CARB and EPA, as well as many manufacturers. The claims and testing methods are questionable. So, if you want to come this Thursday, we'll make some schedule changes.

[jpsimon]

Ok so you don't want a third party to test the exhaust, I see what's going on here

I'm not with any vendor, by the way. I just happen to like their products and think you're marketing strategy is extremely questionable. I'd gladly eat my words if you allowed a third party to do testing I want the best for my car.
