400ex pipe

[Ruby Soho]

What do you guys think of the CT racing pipe? It seems like a good pipe, but ive never heard anything about it. I would probably get the Full system midrange version. Mods in signature.

Im a 400ex pipe shoot out it made the most power out of all the pipes tested even beet hmf. White bros E-series made about the same amount of power as ct but was quieter so E-series won.

My buddy has a slip on and I guess it is a decent pipe but it sounds like dog poo!

well they said the hi output for the 40+ hp and midrange for the 30's-40hp

and i think im pushing low 30 right now so

[maddmatt02]

guess it aint too bad, 27hp stock, the 04 YFZ layed down 33 to the rear wheels I think when dirtwheels threw it on the dyno.

I have a buddy who owns a cycle repair shop around here, and he builds I4 bike engines for racecars, I might have to go get my bike dyno'd after I get the carb dialed in and then maybe again after my headwork. wonder how much more HP you get with the powerbomb header.

Doesn't say how many discs on the E-series? I see it says 95db, so they must have just a few discs on it, not sure what they come with 3-4?
Got mine used with 12 and I know its over 100db.

Says 12 discs on the CT... 102db

[mcleod]

this dyno is for slip-on right?

you have some for full exhaust test?

[maddmatt02]

anyone whos ridden with one of those and then with a LRD pro4, what do you think of this system?

The E-series is 96dbs with 12 disks. If you take the spark arrestor out it will be about 101dbs. I think if you run 6 disks on a E-series you excape needing to jet the carb but then the pipe isn't doing much good since it would be corked up so bad.

Id like to know this too. After I do my engine build later on this summer I think i might put on a lrd full system...

[maddmatt02]

guy who built my engine said run a FCR and a LRD pro4 full system
