Drag pipe w/ or w/o silencer

QUOTE (JP374 @ Aug 19 2008, 07:54 PM) index.php?act=findpost&pid=8636I have a ftz oof pipe on my 250r no silencer just a straight stinger I was wondering if I put a silencer on it if it would help me or hurt me? It is soooo loud w/o it but revs really quick. I rigged up a silencer on it it quieted down alot but doesnt pull threw the gears as fast. My ? is are there any stingers or silencers that I could put on here that wont hurt it. FTZ makes a weld on one.

How ever long the silencer is that you want to put on the pipe ? You need to cut that same length off the stinger tube. Then attach the silencer. You do not want to add to the length of the stinger tube, with a silencer. Adding a silencer to the end of the stinger tube will effect the way the pipe performs.

Ok so if my stinger is say 8" and i want to put a silencer on thats 10" what should I do? If I make the stinger longer w/o a silencer what would happen?

Ok so if i went longer stinger it would slow down the bike? It revs like instantly with just a stinger but loud as hell. I am still getting it dialed in its breaking up on the top end bad but with the silencer it runs good. The pipe was made w/o silencer so I want to run it like that. Last year with my 310 I took it to the dragstrip ran it with silencer on and off and with it off I picked up 60ft times, and 5mph in the 1/8th mile it was wound right out by the 1/8th but with the silencer on it was pulling all the way down the 1/4.... which when racing 300ft I figured it would be a wast to run the silencer. just tryn to figure things out

Yeah ive messin w/ diff ideas. I was thinking of calling up shearer and gettin one of his silencers with the flange & whole nine yrds and just welding that on I dont yet. I have a homemade silencer I have been running on there but when I try to get it dialed in w/o it it breaks up on the top end. I dont know if w/ it off I have to richen it or lean it out it breaks up pretty bad though. Maybe the stinger is too short and the gases are escaping to quickly
