An Interesting Read Here.. Got this from Tanabe Website. If you think a pipe is a pipe, you have no idea!

-------------------------------------------------------------------------------------------------------

The following article has been hosted on Tanabe USA website, and I thought that it would be interesting to post this up as a tech article for the forum. There are also a few other tech articles hosted on the site, so if you would like to check them out please feel free to do so.

Tanabe high performance exhaust systems are made 100% in Japan at the Tanabe Shiga Factory. From the mufflers, piping, and even the hangars and flanges, Tanabe systems are constructed in-house, in their entirety. Each Tanabe exhaust component is made using a high level of engineering, hand-crafted care, and an unprecedented level of quality that creates a special bond with many owners who purchase these unique systems.

The exhaust manufacturing section of the Tanabe Shiga Factory employs some of the most advanced computer aided machinery, precision laser cutting tools, high quality materials and a group of highly dedicated, skilled craftsmen and engineers. During the R&D of each exhaust system, an in-house Bosch four wheel dynamometer is used to test power and function of each exhaust system.

An initial founding member of JASMA (Japan Sports Muffler Association) over 15 years ago, the Tanabe exhaust system is the only one of its kind to be completely manufactured and assembled in-house, in Japan, that is readily available to North America to have the highly coveted ISO9001 certification.

During each phase of production, each component undergoes an exhaustive series of inspections to ensure that the engineering requirements for material quality, fitment, weld quality and function are of the highest specification.

1. SET PIPING & MANDREL BENDING
Piping is the first component of the exhaust system to be created. Using engineering data gathered during R&D, the computer is programmed to cut the high grade SUS304 stainless piping to exact lengths and sections. The piping is then sent to the CNC mandrel bender, where engineering schematics and programs are loaded, and the machine produces exact replicas of the engineering department's production prototype piping. When the batch is finished, the piping is sorted and stored for assembly.



2. MUFFLER CONSTRUCTION
Many parts of the muffler construction phase are a Tanabe trade secret, which helps the exhaust systems acheive their beautiful, deep tone. During this phase, the computer is programmed for muffler type and vehicle application. This determines the internal construction type (chambered, loop or straight through) and most importantly, the density of the new Advantex internal packing material to be used. Each main muffler and sub muffler has a carefully calculated formula for packing material, to acheive an optimal balance of flow and noise reduction. High luster SUS304 sheets are cut to length, stamped with the Tanabe logo, and are then shaped according to canister type. The canister and internal assemblies are then assembled, and sealed by a highly precise robotic TIG welder.



3. BRANDING AND TIP CONSTRUCTION
Branding and identifier plates are tack welded by hand onto the completed muffler canisters, sub mufflers, resonators and piping sections. These identifiers contain a production number, part number, and the Tanabe logo and exhaust name, for authenticity and the highest level of quality assurance. The identifiers help the engineers track any minor changes they may make to an exhaust system design, and are an extra step Tanabe takes in quality production, which helped Tanabe receive the esteemed ISO9001 certification. Tips are designed and constructed in house, and are sorted according to size, length and diameter for final assembly with the muffler and exhaust system piping.



4. HANGAR AND FLANGE CONSTRUCTION
Even all of the hangars and flanges found in Tanabe performance exhausts are completely constructed in-house. A combination of computer aided design, and human interaction are used to create these. The SUS304 hangar's sizes, diameters and lengths are determined during the R&D phase, and are bent and sorted according to vehicle make and model. The flanges are cut from SUS304 stainless steel using a CAD assisted precision laser cutter. The thickness of each flange is carefully determined by the engineering department for each vehicle, depending on placement on the exhaust system. On areas of higher stress, a stronger, thicker flange is used. On areas of lower stress, lighter weight pressed flanges are use. These flanges are manufactured and stored for assembly according to bolt pattern, pipe diameter, and application.



5. EXHAUST SYSTEM WELDING AND ASSEMBLY
Once all other exhaust components are completed, the finished pieces are sent for final assembly and welding. Tanabe's highly skilled welders perform the necessary manual functions that require a high level of craftsmanship and accuracy that are beyond the limitations of machine assisted production. A final inspection is performed on all of the pieces before being sent for packaging and boxing.



6. PACKAGING AND BOXING
The final product is delivered for cleaning treatment, for a quality finish. The exhaust system is then carefully packaged, wrapped, and boxed to protect the exhaust system and it's finish from external damage.



No, Tanabe USA didn't pay me to do this!

Just want to share and educate!!

Buy Quality Stuff also means you will not have fitment issues.

I like Tanabe as a company and their products. Too bad virtually everything about the production side of things in that article can be done in Taiwan now for half the price.

has anybody ever had a straight 3 inch pipe from o2 housing all the way out the bumper with no muffler? Just nothing but pipe...why dont people do that? Aside from it being loud what other cons does it have...and would it yield more power?

This is somewhat of an obvious question, but yes it would be the least restrictive, but loudest option. Some people do it and some dont, most dont cause they like to hear when they are done driving and probably want to be able to talk to people in the car when they drive, i.e. having a muffler.

imo..piping is piping.!! except for the diff metals involved..as long as the piping has minimal bends and is at least stainless..they are all the same to me.!! hell..i have a full megan exhaust with o2 housing and hit 355 hp and 360 tq with just that.!!! so many may say go buy a 1200 cattback when i say get stainless with minmum bends off ebay or something.!! exhaust is exhaust imho.!!

you're trying to make me believe you made 355hp on a IX w/ just a TBE? Or do you mean you made that much power w/ that exhaust and other mods?

if your on a budget, used is nice. ive gone with many used parts on my last evo and srt. i like the fact i can sell the parts for basicaly what i paid for them in the end.
