Whats up brotha, how have you been?

Yeah, we averaged about 24 with that setup. Hell, we averaged about 28 with resonated test pipes and the cat back.

Now you guys got me thinking of upping my pipes from 2.25" to 2.5".:rolleyes:

that should be no problem at all =) stillen claims 54whp or something like that with that 3-combo if you used all of their parts.

I do agree that the straighter design will likely be a little higher, I just don't see it being more than a few horsepower. If you can prove me wrong then by all means show me the numbers comparison when you have your boosted Z and I'll be more than happy to tell you I was wrong :tup:

DDM said his intentions were to dyno his car in its current form and use that as a baseline, then add the exhaust and dyno again for the gains. He was never trying to mis-lead anyone.

Why did they not dyno it with the stock cats? Because DDM has had the cats on his car for months now and didn't want to have to pull them off and reinstall everything stock just to get a dyno number. Using a baseline with his current and showing the increase is sufficient to show that the exhaust makes similar power to other competitors. With his only access to a dyno being another shop that is hard to make appointments, I don't see a problem with this.

I am pointing out that compared to your high flow cat and cat back combo dyno pull compared to your baseline, you made less overall power than the Berk combo did when looking at their individual gains. Yes, the dyno situations were not the same, which may mean we are retarded for arguing about it over the internet, but it's going to be VERY difficult for either of us to prove anything unless we got the same car, dyno'd it completely stock, then dropped the stock exhaust and dyno'd it with the FI cats and CBE, then dropped that and dynod it with the Berk cats and CBE.

I doubt we are going to get the chance to do that, so for now we can continue to try and make our points :icon18:

I don't think DDM was trying to mis lead anyone. I don't know them but I have heard nothing but good things about them. However, IMHO when you are trying to launch a product, you have to dyno the car in its true form (Stock) and anticipate that everyone is stock when they buy your product. This is the only way to have true real gains. What if someone called and wanted to buy their cat back but already had someone else's cats. You cannot give them a definitive answer on gains because you have nothing to compare it to. For them making more power, show me a dyno graph where they made more than 305 with their high flow cats and cat back. All I see is a 296 number. So you cannot say that their combo makes more power.

As far as the boosted aspect, it seems I am getting nowhere with you on that one so I will concede for now.

Like Tone Loc says...

Let's do it!

You will!

I agree with that. It's just not easy for a daily driver to put all his stock stuff back on to do a dyno run. I also don't see someone with berk HFC's already getting a 20 whp gain by adding an FI exhaust. You are talking a 35+hp gain then, and if that's the case then sign me up for that combo :driving:

as far as more power goes, dyno calibration and conditions can play a pretty big factor there. Again, I agree the number from Berk being so far apart isn't as credible as yours, but it was the same car at the same dyno shop so I can't discredit their effort in getting accurate numbers. If you and berk both send me catback and HFC's I'd be glad to hit the dyno for an all-day session comparing the 2 and then I'd send em back, but I don't think you guys will be up for that, lol. Plus you probably have someone much more local that could help out if you wanted to do a head-to-head.

With the forced induction, I have a point of reference for that number based on personal experience between a crush-bent muffler shop job in 2 1/4" piping compared to a 3" Blitz Nur spec turbo exhaust which was only a 6 whp gain on 12psi of boost in an SR20det. If the boost on this 6-cylinder responds that much differently to it's exhaust, I'd be glad to say I am wrong...I'm just going off of my personal experience right now.

Re: the Berk and FI results, it's all apples and oranges anyways due to different dynos and different environmental conditions really, not to mention the whole HFC vs Stock issue. They're both performing pretty well though.

So...what is lower, the FI exhaust, or the chin spoiler?

Or, preferrably, how high off the ground is the lowest part of the exhaust, and where are the low-points located?

The only concern I have about the FI's clearance is that the front of the can-style mufflers could catch on an obstacle like a speed bump or even a really crappy road.

I had side pipes on one of my Mustangs and ripped the right side pipe off when it caught on a speed bump... :(

I would be inclined to weld some sort of cover down there to prevent this from happening (if it's really going to be an issue.)

Lowest point might be the end of the round cans.

Keep in mind, where they are located is in relation to the rear tires and as the car goes over a speed bump, by the time it is on the down swing the front of the mufflers are over the bump. No doubt you will have to be careful and mindful of your exhaust. But you should be like that anyway.

I know I'm careful no matter what, but the only concern I have is when you run into a similar situation as I did when I went into the city (NYC) and enter a strip of road that had warped pavement (looks like the road is dried up lava, with waves in it) and unfortunatly I couldnt avoid all of these 'waves' and I went over one right down the middle where no tires lifted up and BAM caught some of the cross-member/exhaust....

That was both scary and blood boiling mad, but luckily, no dmg was done, just some scuffs...but man I wouldnt want to run into that with this exhaust and have that ripp a whole in those canisters.

Especially if your riding around as low as I am...

Yeah, my side pipes were lowest at the midpoint of the Mustang, so they could easily get owned over a speed bump. I totally forgot to think about the cans in relation to the rear wheels. They should be fine. :tup:

Just to let you all in on what we are about...

Bottom line, "We manufacture horsepower"

We built this car and many like it from the ground up. In this video it made 1000 HP at the tires. Currently it makes about 1300!

:rock:

+Respect for a Mustang owner!

yo everybody should really stop comparing the results between berks and FI...

different cars, different dyno, different methods, different everything...also one has stock intakes the other has stillen G3.... common now... oh and both are not independent tests...
