Custom Exhaust by Mark McDade

[dstewart]

Thanks to Jeff Stern I ran in to a fellow by the name of Mark McDade. Mark has a long history fabricating racing exhaust systems including working with Muzzy's when they where out of Hesperia. Its getting hard to find any kind of full system for the RC51 any more much less anything that will work well with a "slightly" modified engine. Mark to the rescue!

The system was built using 20AWG Stainless.
Using the Akrapovic 45mm SP2 flanges and collars the system starts out 1.75".


The first expansion tapers up to 2" after the fist bend as it travels down. The pipe expands again to 2.25" along the oil pan back to the 2-1 collector.


The 2-1 collector is 2.25" in and stays 2.25" on the outlet for several inches. Mark says he has seen big mid range gains by not expanding the collector outlet too fast.


After the 2-1 collector the system expandes again to 2.5" that feeds the custom AreaP Oval Carbon silencer with billet CNC end caps. 18" long 2.5" in and 2.5" out. I dont think I will be riding at Laguna with this system!




Same with the rear cylinder, Akrapovic SP2 flange and collar 45mm outlet.



Again the rear primary pipe expands to 2" on the way down then 2.25 as it snakes in to the U before the 2-1 collector. Mark did his best to utilized as much room as possible to add some length to the rear pipe. Notice the nicely made sectioned U bend!






I hope to have it off to the dyno next week (expect a call Andy ). Mark has a lot of experience building systems and knows what works. I also had the input from Kerry at AreaP who worked with American Honda developing systems for the RC51. Its bigger then the full Akrapovic but still much smaller then the full HRC systems. We believe this will work very well with my engine combos.









The price was extremely reasonable! Much less then a new full Akrapovic!

Yeah, McDade can make some pretty wicked stuff when he wants to....

Did a couple of pipes for Mr. President back in the day before anyone else made anything for his (then) new gen R1 and before that he made it for his ThunderGuppy. Made damn good hp too. Bof'em.

Can we get some contact info on this guy? I just might need him to modify my existing exhaust. I got to put a wider kit swingarm and I know for a fact the exhaust needs to be set out wider. Let me know thanx! by the way nice bike dstewart the entire bike looks very professionally built, the exhaust is true one of a kind! I likey!

If you need his # PM me.

He reminds me of Mackie, just a good guy doing great work out of his house. Easy to work with, very fair price's and honest.

Well, I woke up the family, pissed off a few neighbours and my garage is now toxic with burnt race fuel

Just fired up the bike for the first time with the new system! Damn its loud, but in that I just had the best sex of my life kind of way! Thats was the first time I got to fire it up since I dismantled it before this rebuild. I also got to test out a new ECU, that works, so I am a very happy man tonight.
