    its OK, but the only thing it does is the higher RPM. you can tell when it reaches that sweet spot in the RPM where it will accelerate like crazy.

    ya, that works good 4 me. i drilled out the dual resonator stinger also, and that seems to help alot. i would rather have the dual, it helps keep the front end down with my OS18TM, lol. it still flips over on wheelies like crazy

    15/64 is a measurement, pronounced "fifteen sixty-fourths" its 15/64's of an inch. I just drilled mine out to that same size today and noticed crazy more performance half way through 2nd gear. Starts to flip over backwards.

    YES. you will almost definately have to retune it, especially if you have 33% fuel, as it has amore sensetive tuning.

    when you say you "drilled out" the stinger 15/64ths do you mean you used a 15/64ths size drill bit and drilled the stinger, or you drilled it out another 15/64ths?

    Yes, you need to retune. If you change the pipe or the air filter you need to retune. If the humidity changes you need to retune. If the temperature changes you need to retune.

    I see a pattern starting to emerge here.

    Waou ! I don't know all that...
    It's very kind of you for all these answer.
    But, for more precision, can some one who have drill his resonator post a picture of it... It's could be cool to see precisely where to drill...
    Sorry for my poor english...

    as a side note on the drilling. you will also notice a difference in performance if your muffler is closer to the header or farther away. from hard use or a wreck sometimes the muffler will move, which in turn will change your tune on your carb. i have been experimenting with one of my tuned pipes from one of my airplanes. its insane performance, but it looks funky hanging off the truck about 15 inches.

    That makes me confused little bit, I have dual chamber resonator so shall I enlarge the exit exhause piple hole with .25" dia or need to make another hole somewhere at end of the tuned pipe ?.

    Thanks

    there is only 2 holes in a pipe(not counting the pressure nipple where the tubing is),where it hooks to the header via the motor, and the stinger, the end the exhaust comes out of (the smoke trail). The stinger is what needs to be drilled out (just making the hole larger), no adding holes. I dont have any pics of it, and I cant get any up right now, but that should be enough of an explanation. If you still need more info on what to drill and where, then ask again, but IMO , if this is to difficult (not knowing what end is what) then this mod may not be good to do till you know more about your truck.

    Ok... Thank you very much David. It's clear now.
    So, if I understand, you drill the resonator in the stinger to enlarge the existent hole ?
    And it's the same operation for a single and a dual chamber ?
    Cause on your picture, it's a single chamber, isn't it ?

    Thank you, Jatomann, another question, after install a dual chamber, the Jato must be richer or leaner ?
    After drill, the performances are very different ? with a dual ?

    WoW Dave .. that was so clear .. also thanks to icepick832 for the explaination.
    But do you think with this little enlargment will make me feel the difference ?

    David .. have you modified your tuned pipe ? it doesn't look like a purly stock one.

    It seems it did help to drill the stinger but I also changed gears so I can't say for shure how much each mod helped.

    I drilled the stinger but other than that no mods. I did sand the blue off of the back half of the pipe and polished it but thatís all.

    its hard to tune like that. you cant just richen it or lean it based on what someone else has done and hope that it works. the best thing to do would be to go back to factory settings and start again.

    +1 anytime you do an engine related mod, be it filter, exhaust, or even the piston and sleeve mod, you will need to retune and not just do what others have done. each engine, even broken in by the same person, will have slightly different settings.
