Dual-Resonated - $1099 Sale $899

*Sale Ends 12/1/15

100 Units in Inventory and ready to ship!!!

The first time this product was released I admittedly did not realize the demand was going to be as high as it was. We worked hard to keep up with the demand but we just could not build them fast enough. Because of that we ceased sales until we could have ample inventory to meet the demand.

Since then we have changed processes in order to keep the flow coming for both our wholesale and retail customers! We have 100 y-pipes in stock an ready to ship!!!













Product Description
Here at TSM our goal is to build parts with only the highest level of R&D and quality. Every product we build goes through rigorous testing on many different levels, from fit and finish to performance and longevity Our Pro Series GT-R Y-Pipe is no exception to that rule. We have been testing different components and trying different designs for almost 6 months in order to ensure that our customers are getting the absolute best we can give. We are very proud of the end result and are happy to offer the GT-R community something that stands right there with the best in the industry.

Resonated and Non:

First off we wanted to offer both a resonated and non-resonated option allowing the customer to decide just how loud he or she wants the car. Our super quite dual resonated design cuts noise as good or better then any y-pipe on the market. These quiet mufflers cut the drone out of almost any exhaust system. They also retain their packing for much longer then some of the less effective units on the market. That means that your car retains the same nice quiet tone throughout the life of the y-pipe instead of the car getting louder over time.

Bellows vs. Mesh Flex

We turned the industry upside down in order to find 3" stainless steel bellow flex units rather than the traditional mesh style units. We have found over time that the web style flex sections break down and ultimately can cause small exhaust leaks. Not only that but most stainless flex section have mild steal crimps which over time can rust which causes further deterioration of the unit.

321 Stainless Flanges

We purchase in bulk 321 vs. traditional 304 stainless steel for the flange material. 321 Stainless has a higher nickel content then 304 which is not only stronger but also creates a much better mate to the tubing. The end result is a flange that is FLAT, will not warp during the welding process at all and stays consistant through time and with heat cycles.

The Merge

We do not buy pre-made merges for these units. Every 90mm merge is fixtured and cut then tack welded together for hand smoothing and port work. They are then welded together by hand in order to guaranty a seamless transition. We find these little attentions to detail are what set apart quality products from the rest and we make sure to take the time to add as much passion to the product as possible.

Internally & Externally Welded Flanges

Each flange is welded onto it corresponding pipe both from the outside and the inside walls of the tubing. The welds are then hand ground on the interior of the pipe and ported smooth. This allows the exhaust exiting the downpipes to flow into the pipe with absolutely zero restrictions! The transition is smooth and without obstruction once the pipe is bolted on.

Back Purging

Back purging is a process used in welding any exotic material that is susceptible to oxygen or any other contaminants I.E Stainless Steel, Inconel and Titanium. There for; cleanliness is key to producing a quality and reliable weld. When stainless steel is TIG welded, the molten pool on the weld side is protected by a shield of Argon gas to keep it from soaking up contaminants in the oxygen around it. In order to ensure a quality weld a "Back Purge" must be used. What this does is fills the inside of the tubing (or backside of the weld) with Argon gas to keep the oxygen out, or purge it from the chamber. This process not only strengthens the weld immensely but keeps all contaminants and oxygen away from the molten metal. The results is a weld that looks just as good on the inside as it does on the outside. When a back purge is not used in conjunction with stainless or other exotic materials the weld will soak up the contaminants in the oxygen making it porous, brittle and immensely less reliable. This will result in welds that will crack break or overtime deteriorate.

Included Hardware

We include RemFlex exhaust gaskets for both the runners and the primary pipes. These gaskets are much better than traditional metal exhaust gaskets. They are designed for a total seal and guaranteed not to leak at all. We also include grade 10.9 flanged bolts, washers and nuts. It is very easy to cheap out and cut corners on little things such as these, however every little detail is important to us when it comes to quality.

Below is a full list of the features of the new TSM Y-Pipe:
  • 90mm Primary w/ 76mm Runners
  • High Flow/Minimal Angle Design
  • Fully TIG welded with a sealed back purged process for maximum durability and strength
  • Internally and Externally Welded flanges

  • Proprietary 321 Stainless CNC water jetted flanges
  • All flanges engraved with the TSM logo
  • 3" Stainless steel bellows
  • RemFlex exhaust gaskets (Guaranteed Not To Leak)
  • Grade 10.9 flange bolts and nuts for install
  • Each Y-Pipe comes with serial numbered name plate and (KILL)
  • Life Time Warranty against cracking or build defects

Where are these actually welded/fabricated ? In house or like most out sourced overseas ?
They are outsourced but not overseas. And they are quality control checked with a fine tooth comb before they go out as we pack each one with gaskets and hardware before it is shipped.

Thanks, good question

Cicio...I know loudness is a relative term and different from person to person, but I am looking for more of an F1 sound (and louder) than the SBD midpipe I currently have (it is resonated)! You said the resonated version is very quiet...can you expand on the sound of the non-resonated version? Thanks so much, Todd

Are you on stock rear section right now?

Our non-resonated has a slightly unique sound just because of the difference in design.

Don't get me wrong it's not like earth shatteringly different than say another non-resonated unit when it comes to sound but it is slightly just because of the way the exhaust merges.

Unfortunately you will never get too exotic or a sound out of a GT-R exhaust but I also love F1 and old exotic sounds. I would like to think ours sounds a little closer to that style sound but that could just be in my head because I like it


I will get a sound clip for you today or tomorrow of a car on the dyno with downpipes and our Y-Pipe. Even then it's hard to tell as it depends on the mic used and the speakers used to listen to it.

Sorry for the somewhat vague answer but I wanna be honest and that's just a hard one to answer directly without tons of opinion as well as hard to explain in words.

I hope what I was able to try to portray at least helps a little and I'll try to get you that clip!

Looks great Cicio.

As for anyone with the stock exhaust.... You can not go wrong with the unresonated pipe, adds a bit of volume but is certainly not overbearing, makes the car sound like a sports car


These will sell quick i bet!

What's the difference between this y pipe and the one ams offers.
It's a totally different design as far as bends in the piping and resonator location. Also they use bellow flex rather than mesh which was stated in the first post. I've seen this mid-pipe in person and it looks a lot bigger than the hks mid-pipe I had installed on my car. The workmanship is top notch too.

Looks great! You guys should post a sound clip paired with a stock exhaust. I would like to hear the "slightly unique" sound.

Any idea where they are made in? I find it hard to believe that an item like this is not made overseas.
I have no idea where they are made, they just show up like magic.


If I wanted to tell everyone including my competition who I found to build a quality pieces I would have in the first post, but thank you for asking.

These were designed and tested in house until we couldn't keep up with the demand, then we sourced a company that was up to the task of producing them with a level of quality we were happy to put our name on.

I appreciate the concern..... would you like one for your car? I would happily give a local owner a great discount.

It's a TSM product not a SBD product. Like posted before I have seen this in person, very good quality
I normally would just let this ride, but the only 90mm Midpipes we make in 2016 (Non-Resonated) are 100% Made in the USA.

We no longer sell a Resonated design, but this looks like a quality piece....regardless of where it's made.
