A nice gentleman with his C43 from North Carolina arrived at BMS shop at around noon on Friday, Oct 10. Yes, finally, the first test bed for the system is here! For the next couple weeks, we will be developing a stage I & Stage II exhaust system for a C43 lineup. Jeff's car is next!



And the hardest part of this project began: R&D

The goal: 15-20 HP increase
The priorities: performance, emission legality, style, and of course sound
Perimeter: Downpipe Back



And after few hours of planning (and some arguing), the few of us agree on the 1st setup we will do for the 1st dyno. Here is the details....

I. In place of those OEM catalytic converters, there will be dual BMS Spec'd Hi Flow Cat. These CATs are tappered and angle to maximize air flow distribution. Keep in mind that most OEM cats are only 70% effective. The dual 2.5 cats will be complemented by Stainless Steel Heat Shield. If one choose to go full racing, we will place a Xpiped muffler instead of the CATs here.

II. In place of the OEM resonator, there will be dual staggered setup Magna Packs. These have smooth core and the most densed in the market. They do have stainless mesh wrapping the core. In short, AIR will flow through the core, while the sound will disperse without any turbulances/restriction. OEM resonator (oval) creates turbulances.

III. Custom fabricated high flow Y to 3" Mandrel to BMS TURBINE SYSTEM. This is where things are getting techy. The Turbine is a new technology. It is designed to create vacuum in the rear, hence the suction on the front. It cools down and increases flow. Think JET Turbine - same concept. There are so much details on this, let me know if you guys are interested.

IV. Stainless double wall dual tips. Same size as the OEM. We can also put FABULOUS sytle oval tips. Its all about preference!

I realize that this is a lot of talks without pictures. Please be patient.. we are having a blast here, and will share with you all as soon as the ready system is done! Meanwhile, enjoy a few teaser pictures..........




Bad angle - turbulance in the air flow, restriction, and excessive heat point!!


Mr. Conrad Jones is making his point to the rest of the team. yes yes, we got your point.


Few R&D stuffs. What fits and what not.


To Be Dual or to be single. And that's the question!


The misterious yet effective turbine!

STAY TUNE FOR UPDATES....
PS.. Jeff, you might go for stage II...
