40 HP is a lot of power to gain from exhaust. Thats supercharger teritory on a CLS.

unless you made a custom header (x2) with each its own piping (so each side of the motor is seperate) that'd be the only true dual way to go. and then the pipes would be scraping the ground most likely somewhere under the car. So i concur. not worth it
great idea tho... i'd still want it if it was practical

Werd. You'll lose power unless you're supercharged and even then chances are that just a slightly larger diameter exhaust system is all you need. Total waste of money to have one custom made.
No way in the world they're making 40HP more with true duals.

And the dual exhaust wont add much, if anything. I honestly wont be surprised if you lose power.

And yes I already have it, I have had it for 3 years now.
Its probably just Tanabe low on funds and remaking exhausts on just about every car to stay in business since times are hard.

allow me to clear some shit up.
the true duals on richies setup gained an average of 40 WHP throughout the powerband. that means it closed a huge TQ gap in the powerband and provided power the whole way throughout.
as for PEAK gains, the exhaust gained about 18 HP at the PEAK interval.
true duals is definitely the way to go. im currently revising my setup and i can say that it SHITS on a single to double setup power-wise.
i would rather have power throughout the powerband than a high peak.

The tone of my exhaust is like HKS' Exhaust its your typical J-Spec exhaust but its not overly raspy, its all deep tone but not louder than 96 DB, compared to my magnaflow exhaust I had its wayyyyyy more tolerable on the highway as opposed to magnaflow when it comes to drone, and personally I think it sounds better.
But its all tone, with a very very slight rasp just to let you know "hey this is made in japan"
http://www.youtube.com/watch?v=UfkBoVoELck Imagine that but deeper that is exactly how it sounds. You know sounds like a V6 as opposed to a inline 4.

Please explain how you can get an avg of 40 hp when your peak number is 16. ITS IMPOSSABLE! Its grade school math.
Look at his thread for an explanation. He even took down the graphs and recanted his 40hp claim. He is no longer claiming it. The dyno was done incorectly and therefor gave false gains on the avg number.
Way to clear some shit up!

alright. whether it was wrong or not, it is still possible to have an average of 40 when the peak is 16. because GAINS are the difference between the numbers before and the numbers after. then you find the AVERAGE of that.
simple grade school math.
peak hp is measured at the interval of 5252 on the RPM band. PEAK does not mean the highest gain on the plot, PEAK means the power gain at that interval.
perhaps its not grade school math, considering YOU dont understand how an average over a plot is factored.

Take a look at this dyno graph. If you look at the HP gains for premium fuel your see that the peak hp gain is 47 hp. That means you will see no peak higher in the dyno.
So take all the gains over the powerband in the plot below. On the attached link.
Thats from the 2+13+32+26 and so on for thier respective rpm.
The totals = 331. Now you take the 331 and divide it by the number of rpms tested, wich is 13.
So we have 331 divided by 13 = 25.4.
So 25.4 would be the avg HP gain across the rpm range.
Phee you are wrong and don't know what you are talking about.
Please show me the math where the highest number you factor into you avg is 16 (peak) and end up with 40 for an average..
The above link is for a dakota because I could not find one for an Acura. It is for Phee's learning purposes only.

I must be a mathmatical idiot then because when I see an average of 40 i would assume that means the peak has to be 40 or higher whether you are talking about cars or anything else? Seems logical to me. If the average was higher than the peak then why does everyone go by peak then?

Stock TL with RV6 Exhaust
20 WHP peak gained
15 WTQ peak gained
*MOD EDIT*
Stock TL with RV6 Exhaust and V3 Jpipe
16 WHP peak gained
19 WTQ peak gained
*MOD EDIT** - requested by Richie.
MOD Edit??????? I see he had the graphs removed and the 40whp removed. And is no longer claiming it?
That sounds like a recant to me??????
Im not dogging richie or his product. It is still a kick ass system with great gains across the entire RPM range. But in no way did the graphs show a 40whp gain in any way shape or form.

Have you seen my Sig, Id waste you! lolAlso are you saying that all tuners, and dynos take thier peak number from 5252 rpm weather or not that where they made thier peak power? WOW!

If you check the math for the average HP and TQ on the dyno sheet, the average TQ &HP for the stock tl is 154ft-lb and 141hp, average for the RV6+V3 is 114ft-lb and 105HP
If you missed it, stock=154ft-lb vs RV6+V3=114ft-lb Check the link above on page 4.
The dyno is using HP and TQ numbers that are recorded BEFORE the run at around 2500rpm and averaging it with the peaks so the average HP and TQ are invalid.
