Well then why don't you put this train back on its' tracks rather than just inflate your post count with useless post on subjects you know all the answers about.

Your right I said lightened brakes will not give you better acceleration, lightened rotors however will; if the poster would have used the correct vernacular and we wouldn't have this issue.

They also said in the article that the boost in HP was due to cooler weather during the second run, the dyno sheet gives a 10HP upgrade over the stock system.

Midpipe 8hp for $270 so $33 per HP

I stand by my original statement, show me a non FI mod that gives that kind of bang for your buck. (not nitrous, that's apples and oranges here but also a great deal for temporary use). Not the best acceleration (I would go with BHR flywheel before lightened rotors anyway) or best weight savings, best horsepower per dollar spent, especially if the stock cat is in less than great shape. I'm not sure why you felt my responses were directed towards you. Or where you got your 1k price tag, but if you read what I wrote I just mentioned mid-pipe.

You've got to be kidding? You must have been the only person on here that read lightened brakes and didn't think brake rotors.
Just admit that you initially only thought of brake pads or calipers and then when it was posted that rotors do in fact rotate you slapped yourself in the head for not even thinking about rotors as being part of the brake system.

Come on man, stop trying to make others look like idiots for not using the correct vernacular when you know that it was you who goofed.

We all make goofball mistakes, just admit it.

"Your" should be "you're". "Vernacular" = "colloquial speech", so you're calling for what? Midwestern? Gangsta?

Again, if you read the article you linked to, the gain claimed was based on swapping in a midpipe in place of the stock one which had a clogged cat.

You cannot follow a logical argument. 1) you first claimed ditching the cat was the best value in $/hp. 2) I pointed out that this is not true 3) you brought in the subject of midpipe, making further claims based on a misreading of an article you linked to. You keep on bringing in more not relavant stuff to support an untenable position.

Simply replacing the stock midpipe/cat with a catless midpipe with no further tuning stands a decent chance of not only losing power, but also driving the AFRs lean at WFO near max BMEP. I know this because I've tried 3 different manifold/header combos, 4 different midpipes, and 2 different catback setups in various combinations with each other. and watched what happened to the afr's and maf's as a result. It's also quite easy to kill your hp in the process, and again, I know because I've done it and dynoed the loss.

$1k/10 hp = $200 midpipe + $300 catback + $600 AccessPort & MM tuning (optimistic)
$2k/10 hp = $500 BHR midpipe + $800 Greddy catback + $600 AccessPort & MM tuning + $300 AEM or RB intake

Look up posts by Eric Meyer to see how hard it is to get any significant hp gains from a n/a renny.

Again, and finally, for the OP. Get what you like in terms of sound and looks. There is very little if any hp to be gained with simple bolt-on mods. Personally, I liked the sound of the stock manifold + stock midpipe/cat + Greddy SP2 cat-back, best: aggressive, but no drone at cruising rpm. I didn't find that the header (Garage Line) made much difference in sound. Any midpipe will tend to drone. Aftermarket midpipe + stock exhaust is tolerable but sounds stuffed at high rpm. Any no-resonator midpipe will be brutally loud. I measured > 100 db with one and the SP2 together, inside the car with windows rolled up.

oh man, I'm at Hyundai dealership now waiting in the room, dead quiet here and ur post made me burst out laughing u dick. lol

The first thing I did when I saw this was search for a lightened brake kit. Rotors were not the first thing on my mind. Maybe I am crazy but I have always seen and heard rotors being referred to as rotors. Maybe it seemed like I was being a dick about it, but I am sure some people would read this and go and try to buy a big brake kit, or new calipers for higher acceleration. Go to a shop and ask for new brakes and see what they hand you, I just don't think I am alone here in being a little **** about the difference; but no offence to you, maybe it was just a bonehead mistake in thinking.

What are you talking about.

My comments:
1) removing cat best bang for buck
2) new brakes won't give you better acceleration

you make a statement about BHR findings, which I have not seen, and therefore do not intend to argue

3) in response to your statement I find a dyno in which a person had a HP improvement with removing the stock cat (see statement 1 above) Notice my original post said nothing about what to replace it with, just that the stock cat is a source of restriction.

At this point brake rotors are brought up

4) I agree rotors are spring weight, but at high cost
5) In response to your assertion I misread the article, I cite that the small increase in HP they saw between catless and HJS cat was attributed to cooler weather. I then post the cheapest way to remove the cat (see statement 1 above) is a $270 mid-pipe.

I am not sure how that doesn't follow a logical argument, or how you can consider "removing the cat" and "replacement mid-pipe" as unrelated in this conversation. All cat removal mods are to either add a straight pipe, resonator, or high-flow cat. I have not insulted you here, so I am not sure why you feel the need to be so surly with me. I don't think you have "proved me wrong" when you have no article, dyno, MAF diagram, or even a conversation to back up your statement. If Charles found that, then I believe him, but you have shown me nothing but slapping his name on your statement. I brought up a Dyno that seems to add weight to my argument. If CRH and BHR have proof that 8HP gains are all due to the stock cat being partially clogged and that there is no gain between cat-less and properly flowing OEM cat I would like to see that. And like I said I would most likely believe it. But I for one saw a nice improvement with my cat delete, as have others so until shown otherwise, I am sticking to it.


And I believe you could consider the manner in which mechanics or motor heads talk as vernacular.

"Again, if you read the article you linked to, the gain claimed was based on swapping in a midpipe in place of the stock one which had a clogged cat."

How exactly did you manage to get CRH and BHR associated with the magazine article?

For once, I agree with TeamRX8.

Unsubscribing.

WingleBeast

I never associated them with anything. You claimed they found cat-less to not influence HP. Not sure how you think otherwise...

The article said they suspected a clogged cat, yet after it was replaced were still having high end HP issues so it was not definitive that it was the culprit. Now I think you have the reading problem...

Thread bump!

Why has no one stated getting a street port done?
I don't see why a mild street port wouldn't give a couple more HP for the small cost? Though the rx8 does already have big ports, polishing them up and porting them out a bit should give some gains, at least that is what pettit racing states.
