True Dual exhaust?

K I am about to build me a custom True Dual Exhaust on my TLP. But b4 i do it, Do you think i will be gaining anything? I was going to put 2 new Flexible pipe, 2 high flow catalytic Converter (magna flow - something i stock at my shop) a small H pipe to put the O2 sensor in so that it can read both side of the exhaust, No resonator and two magna flow str8 through performance muffler 2/14 all the way? what do you think? Custom exhaust is my profession been doing it for 13 years. so b4 anybody think its impossible its not.. JUST NEED OPINION ON WHETHER IT WOULD HELP? JUST KEEP THE COMMENT COMING.. I AM STARTING TOMORROW AND I WILL TRY TO TAKE PICTURE OF WHAT I GOT SO THAT YOU GUYS CAN SEE WHAT IM TALKING ABOUT

I don't think it would add anything...But that's me and I don't know much. I think more than anything it would be original, and loud.

How will you know if full duals add HP and improves performance? Answer: You wont.

Its called taking your car to the dyno before and after the installation....

How will you know if you have no idea what you're talking about? Answer: I just told you.

I dont think you will gain any. Most of the gains had from our exhaust is in headers. Only way to know is to dyno before and after. If i did any thing i would put a in 1 out 2 muffler where the res is and use that as the Y pipe and run 2 all the way back to 2 custom magnaflow mufflers.

I say do it, on the condition that you record the sound and let us hear it!

About the details...

Are you completely separating both exhaust banks (with the exception of the O2 sensor crossover)? In other words, ONLY 3 cylinders to a pipe? Because in this way, I do think you can gain some power. Of course, the dyno is the only way to prove it. Anything is better than the OEM J-bend when both bank's collectors merge.

The only concern is finding enough space for the additional piping underneath the engine AND making both pipes of equal length (since the firewall exhaust bank is a little closer to the mufflers than the radiator bank).

Even if you don't make extra power, if it sounds good, that's good enough. The crossover will prevent the uneven snorting of old-school domestic muscle cars and the equal length pipes will allow the exhaust gasses to escape the system at the same time.

You have the potential of two bonuses in doing this mod. Let us know how it goes.

yup 3 cyl per exhaust. THe only mod i got right now is intake nos and blah blah.. K i ran at the track in baytown... no spray = 15.1 Spray i got down to 14.3... I built a DUal exhaust for 2 v6 accord already. They love it. it sounds just like a g35 and thats with dynomax turbo mufflers... As far as the gain both have told me they gain alot. but no dyno :/ ... I test drove it i can feel a better pull on the accord from 0-60. BUT im thinking The TL would be different. I DONT KNOW

Thats what the J bend is for. To Equalize the 2 sides.

Even full-tank, half-tank, or empty-tank of gas makes a difference in acceleration times. I don't think the combination of extra cat, muffler and large diameter metal pipings will just weight in at a couple pounds more. Plus the fact that increased exhaust flow after the exhaust manifold won't do much to the TLp engine, unless there are other mods such as intake, enlarged throttle body, header, PCM tuning, etc.

Wow, a dyno. No duh.

I wasn't asking you, genius. I was asking dirtyjohn. That's why I quoted him. What you would do is irrelevant, just like your post.

IF you don't have any positive comment dont leave any.

Im just saying i didnt know the outcome of how much of a gain or loss on the accords i work on because i didnt dyno it. ALl i said was it felt like it did gain something.

AND DYNO everybody knows that dynoing it is only way to find out. IM just trying to get a guesstimation b4 i do it. DYNO will be done on my car when im ready to start on the exhaust.

I meant in terms of gas flow. Having to turn 162.5347° before the merge (it's not quite a full 180°) will slow the flow. I'm not knockin the Honda engineers, they did what they had to do.

I say just do it and find out if it was worth the effort. It's all about trial and error. Some one has to do it and if it works, you will get all the credit for it. Most of all Mike won't have anything else to say in this thread

Yea its not good but its how you equalize the length of the 2 sides the best, and make do with the room you have

the TL's so heavy that the extra lbs. won't do anything... 16 galons of fuel is MUCH heavier than a few extra lbs. of metal, so of course it affects the car more ... not enough to make any difference, tho... it'd be like him putting a textbook in his car, which isn't even close to 0.5% of the total car weight... i.e., a change THAT small on such a heavy car means absolutely nothing...

If he's got headers and such to combine with his exhaust design, I'd be surprised if there weren't any gains and the sound alone would probably make those extra lbs. that Ms. Annorexic over here is so worried about entirely worth it

You can't read.

No aftermarket company has developed a true dual exhaust for a TL. Why? Because the gains, if any, are not worth the trouble. They have to be done in conjunction with addressing the intake side of the equation as well. If a CAI and a cat back don't provide all that much addl hp, why would a full dual exhaust by itself?

Now you're on the right track -> Headers. Headers will give a significant boost in high rpm hp. But without headers, the little power gain from bigger diameter hardware and plumbings (downstream of the OEM exhaust manifold) also means absolutely nothing to such a heavy car.

i know its an old thread but did you ever think of maybe making it dual to the cat then maybe a lil thicker pipe to the split and remove the mid cat

kinda best of both worlds

i dunno

how would you hook up 2 cats to the ecu and make it work correctly? i would think that would be an issue.
