A friend of mine just got a used DC5 Type R muffler "Axleback" and he isn't 100% positive he got a Type R muffler and not a Type S. Are there any markings or part numbers on the muffler we can look for? The bottom of his muffler reads
" Honda Futaba 1052"

Thanks for the help.

 

The part number will differ. check one on a 2005/6 -S stock

 

I don't have a 05-06 muffler around to check. I'll do a some looking around for a type s part number.

 

Okay i did a lot of looking around and was only able to find one part number. Looks like the 06 Type S muffler is a "Futaba 1060" part # as seen here.

Still haven't been able to find any part number for any year DC5 Type R. Hopefully someone will chime in with one.

 

If his says 1052 and stock S is 1060 then it's different. Doesnt he have any RSX-S friends that can just check there's? I'll check mine.

Where on the muffler does it say?

 

Thanks for chiming in. It's stamped on the left side toward the muffler tip. It will say.

HONDA
10XX
FUTABA

I'm going to remove the piping on the muffler today and i will be able to look inside the rear of the muffler and if it's a Type R i will be able to see the door or gate that allows for the chamber's to be bypassed. Ill update later tonight.

 

does yours have this polished tip? Not sure if they are all like this or not.

Okay i just got back from the shop. I cut the rear section of piping off and sure enough i looked inside with a flash light and there was a bypass gate about an 1" inside the muffler inlet. I pushed the gate open fairly easy with a screw driver. It feels spring loaded. I was also able to measure the ID of the muffler inlet. It's about 2 1/8.

I hope this helps someone since the 05-06 Type S muffler and the Type R look VERY much alike from the out side.

TYPE R = 1052

05-06 Type S = 1060

 

So what does that exhaust flapper gate thingy do? Better flow?

 

guessing it opens up at WOT:

 

At around 5000RPM's the gate will open up and bypass two of the three chambers. Which gives the muffler a pretty much straight through route. I read at 8000RPM's this muffler gets rid of 2/3 of the back pressure that the model before the gated Type R muffler couldn't. So I'm guessing that was the Type S muffler.

 

That's sweet. I <3 OEM Honda

 

Does the DC5 exhaust catback will fit bolt on with the catalytic converter type s 05-06. Must I do modification to fit exhaust ?

Thank you!
