True Dual Exhaust System Feeler

Is there any interest in a true dual exhaust system. I was talking with my friend that's made a few exhaust systems for TSUDO and he was showing an interest in doing an exhaust system for the 7th gen accord coupe V6 and 4 banger. I was telling him that a true dual exhaust system might be better for the V6. I dont believe there is a true dual exhaust system out there unless you make it custom.

Some links to some exhaust systems he's done

true dual would be all for show, and what is there to see underneath a car for show anyways. True dual would also show a significant loss in power. A X-Pipe or H-Pipe would be way better than true dual.

and Tsudo is crap, they can continue whoring their products off ebay. sorry no offense to you but I'm just keeping my people on V6P informed.

what if they use like 1.5 piping all the way? wouldnt that compensate for backpressure etc for the v6 at least? for the i4, it wouldnt do squat except for sound. As for tsudo, you know people might buy becuase they prefer cheap stuff over quality that works

I used to think TSUDO is crap but why? I'll be honest but I dont know too much about how piping works and exhaust work but as long as the piping is done right, shouldnt that be okay? And it's a hell of a lot cheaper than the alternatives. When it's piping and exhaust, I dont really see how there is that much of a difference compared to like greddy and borla etc. I know if my friend does make an exhaust system it'd be a hell of a lot cheaper than a brand name exhaust system.

So help me help my friend make a better afforadable exhaust system. So no true dual and go for an x pipe or h pipe?

1.5 inch piping would be a downgrade from stock and in time would make your car choke it self to death. Plug up your exhaust and see what happens to your car..


KPdoughboy I would go with a 2.5 inch x-pipe

Just curious but what bad things have you heard about TSUDO parts other than they whore their products out on EBAY and they're not a brand name. My friend doesnt really get any complaints except there was one incident with his TC headers where the MFG plant messed up on the final product but he spent a lot of time and money to correct the problem.

So other than nighthawk is there any interest in a new exhaust system? Should my friend just kill this project because it's going to be branded by TSUDO and made in China like the majority of aftermarket parts.

the majority of aftermarket parts are made in Japan. There is a big difference between the two. Also there is a difference between China and Taiwan as well. From experience, China metal sucks, and their weld job sucks also.

especially the XS power crap, which i believe are made in china. i've seen way too many exhaust leaks from their headers, and exhaust etc.. all from the weld on the flanges =\ You get what you pay for.

I can't vouch for the metal but i did a quick search on that and it looks like most of Asia gets their raw metal from Australia. I couldnt really find anything else except that so I can't be sure. As far as the quality of the welds and piping, from what I've just seen from other forums it seems like theyre okay. And my friend just started doing exhausts for TSUDO and those would include the 08 XB, TC, and the 08 Lancer which all seem to get good reviews. Only complaint I could see was that people thought the TC exhaust sounded too ricey. And you'd be surprised how much of Japan's stuff is actually made in China.

well, i wouldn't be suprised as I've done alot of business in Japan and China. China happens to be the biggest exporter as we already know. However the quality and craftsmanship of the brand name exhaust that is expensive such as greddy/trust, Apex'i, Tanabe, RSR, etc. are all made in Japan. OBX on ebay is made in china, however there is a Japanese OBX company..

With all that has been said is there any of you still interested in seeing a new exhaust system by TSUDO?

yea you dont wanna go too small..but nighthawk wouldnt a better alternative be 2.25 inch piping..i mean our cars DO need the backpressure

He's suggesting the 2.5 inch if you go with an x-pipe. I myself will probably be going 2.25 inch all the way from the precats to two dynomax resonators, then dual electric exhaust cutouts (for when i feel like sounding like an indy car) finally into two magnaflow mufflers.

I dont understand this whole "true dual" thing. In common terminology true dual can incorporate an H or X pipe for exhaust scavaging purposes (i.e. Mustang) but it wont come down into a single pipe for the length of the car (i.e. Camaro). Having a true dual as you guys describe it (2 totally seperate exhausts) is about the dumbest thing you could do. You would almost lose all driveability with that setup. It would run like hammered dog **** honestly.

Damn i've always wanted to know what hammered dog **** runs like. Anyways, several people have had good results by running such a set-up. You just cannot go too large on the piping, as you will lose wayyy too much low end torque as you mentioned.

You lose almost all of your scavenging ability without some sort of crossover.

that whole backpressure thing i've never been worried about. with an X-pipe, you would see consistence smooth flow from both heads, and the X gives enough needed back pressure. If you are really worried about back pressure than I'd go with the 2.25 H pipe.

I agree, but i still haven't decided whether to go with an x-pipe or an h-pipe. X-pipe's tend to sound a little raspier, but since i'm not too concerned with noise, i'll probably stick with that. Especially that in the past they've been shown to "flow" much better than the h-pipes(Mustangs).

An H will flow just fine. With a 3.0L you shouldnt have to worry about the difference between an H or X.

^^Alrite i'll consider that also. Question do you think i should put the exhaust cutouts after or before the h/x pipe?

On topic:I think if you can make an affordable dual system, that will last and not rust away, your buddy i'm sure will have quite a few customers. Just make sure some type of crossover is included as has been mentioned in this thread.

Wow, I thought this thread was going to die. Like I said before I'm no exhaust performance expert so yeah, I made this thread to get ideas from you guys on what to do. I only thought of the dual exhaust setup because I thought it's different and might yield better performance. I haven't been active in V6P for a while now and when I was active it was when Sick6speed (I think his name was Andy) did his dual setup. So it sounds like 2.25 piping with an x pipe is what the consensus is?

My cousin who does lots sales on ebay wanted to try car parts from China. So last summer I helped him pick out about 10k worth of headers, exhaust and blow off valves. Everything looked great when it arrived but soon he was flooded with complaints of fitment issues and cracking turbo manifolds. At first he did exchanges and partial refunds but after a few months he just gave up. I took a bunch of stuff home hacked it up with a sawzall and practiced welding it back together.

Thats true, thats why i'm going the custom route. I'm sure when i'm done with my system it would have cost more than most systems out there, but it will turn out the way i want it and be full stainless steel. So your statement is absolutely correct, and agree that it should cost a little more to encourage durability.

My friend is also interested in making a J-Pipe as well and will probably want to sell a whole kit from J-Pipe to a new cat then the exhaust system. I'm thinking his greddy sp style exhaust is what he'll use. It's his more quiet exhausts.
It would either be one or the other though. You can't use a J-pipe if you are going true dual. With a J-pipe you would be going into a single collector, where as with a true dual the only the pipes would meet/interconnect would be with an H/X pipe. So if he is still thinking of the J-Pipe, it would have to be sold as an individual piece for those people who want to stay with single piping.
