T5s or T6s?

[MacRacer1]

Which exhaust T5 or T6 sounds better and adds more horsepower????????

[donkeypuncher]

the sound is pretty close to the same. the main difference is that T5's respond better to porting then T6's do. so if you plan on having your cylinders ported then go with the T5's. if you just plan on only using bolt-ons (filter, cool head, adj. timing plate, etc..... )then run T6's.

ok i am probably one of only a few handfull that have had BOTH pipes on the same bike/ built motor. it is a 350cc stock cylinder'd +4 timing dyna CDI 30mm pwm's v-3's very agressive trail port, 130 transfers, 195 exhaust. pods, 20cc shelf dome'd cool head, 15/ 38 gearing, its my trail put put bike and this is what i think:

 

the t-5's seemed to have a lil stronger bottom end and had decent overrev but not that great. power was pretty seamless through out riding mostly trails and dunes/ trails.

 

the t-6's i felt fit better look better and have much larger and longer chambers. the front curve is very nicely built and the chrome is great. the silencers have 2 mounts instead of only one like the t=5's and they cleared the carberators better.. overall i think the t-6's are built much better and are an improvement DESIGN wise over the t-5's for sure...

 

power wise. the t-6's definatelly have a much stronger hit and midrange revv power is much stronger, acelleration wise, when on the pipe seems stronger but shorter time wise. the are more "zinngy" like a cpi on a ported motor BUT it really matter'd what gear i was in they seemed to fall off the pipe easier and didnt have really anything for overrev they didnt fall off on power on top they just seemed to flat fall off completely. and just wouldnt support any overrev at all. i am going to try some more jetting changes and maybe drop a gear on the front as my gearing was really tall also. the pipe "ping" is much more pronounced on the t-6's also.

 

if i could get on a dyno i'd love to compare the pipes back to back i still have the t-5's

 

if i was to describe the power it'd be like this ( dont laugh now)

t-5's: burr BINGGGG uhhhhhhhhhherrrr....puh

t-6's burrrrrr BINGOBANGO puhhh.......u.....h...nope

good review! theres just one flaw with testing both sets of pipes on the same motor...if its ported for the t6's then its obviously gonna work better with the t6's then it would with the t5's (and vice-versa). if you had a two bikes to test that had the same type of port work but was ported to match the different exhausts, that would be the best way to compare the two. but like i said, it was a good review and its nice to hear from somebody that has had personal experience with both sets of pipes.

I run t-5's and my buddy has t-6's. We both have the same port work done and similar mods. His bike falls off the pipe really fast. When we race, he pulls on me in the beginning, but I always pull harder on top end. Seems like the t-5's respond better to mods also.

[MacRacer1]

yeah thats what I have heard to that the t5 respond better to mods than the t6.

[camatv]

the porting in my trail bike should support the t-6's better. at least i would think so if the t-6's had more overrev, or didnt "fall off the pipe" then i think they would be better than the t-5's maybe t-7's they might fix that flaw?? that total lack of any overrev at all is what makes them stink. they feel like stockers on top.. just puh nothing there.. t-5's have some overrev but not much.

 

and to answer what do i mean by overrev. a pipes makes power up to a certain rpm. then they start to fall off thats the feeling that the pipe stops pulling on top some pipes the fall off is more pronuced and on others its barely ever felt. the best overreving pipes i have personally had were the SST"S they fell off but not by much, and would support a longer shift range. . the second best were the pro circuits. NOW to also answer any confusion to what i said. DRAG pipes like the cpi's and shear's MAKE HP up and over the normal overrev point of trail pipes. thats what makes them drag pipes they make power between 8000- 10,500 rpm's MOST trail pipes make hp in the 5800-7900/ 8000 rpm range then go into overrev. if you have a dyno graph you can see it.. after the peak HP number look at the graph you will see a gradual decline in hp but the bike may rev out another 1200 rpm's or more. the t-6's i bet if dyno'd drop of very very hard and fast...

I like T5s better if you are going to do any porting they will work better IMO I even had a set on my little cub and it was super fun to ride. As for the differences with porting. It is very much related to the shape of the exhaust port roof and exh duration . The T6's design would tend to run better with a rounder roof than a flat EXH roof. They also have a tuned length for running at a lower rpm range than a drag pipe or the T5s for that matter. If a longer tuned length pipe like the T6 were used on a higher exh port you would find that the stinger size is more than likely too small to try to turn 10,000 rpms. If u. take the T6 tuned length of prolly 38" or so and do some engine and pipe builder math you see 192 degrees of exhaustX 1700 ÷ 38" tuned length you get 8589 RPMs for approx best HP. Change the EXH duration to 198 and you still get just 8857 rpms. Still a low Rpm for high duration with a shorter pipe you see quite a bit more effect with porting but the volume etc needs to be right I like the T5s quite a bit better on most any bike but stock .

well dang.. what about the tq curve.. i would rather trade the higher exhaust for the smaller increase in rpm,s but thats just me.. what about the t-5's what tuned length do they support. never really did any "builder math" like that.

 

what other measurements do you need to have? the t-6's have a larger chamber, and a lot longer length. i knew by looking at them that they would be a better midrange pipe.

 

and in all honestey power wise, i'd actually rather have the fmf sst's than the t-5's BUT the t-5's DO sound a lot better...

[potpye]

Porting to the pipe is key for best performance, i loved my t-5's but with my setup the CPI inframes gave me way more power all over the board. The t-6s feel really flat to me on any bike I have ridden so I dont recommend them.

[jlevasseur]

If you talk to some builders you will find that most of the prefer the T-5 or the T-6 especiall if there is motor mods. T-6 seems to work ok with a stock bike but thats about it. They both sound the same if you are running Tommey silencers. Different silencers can change the sound.. The T-5 is an allaround mid range pipe. Good Luck !!

[OLD FART]

My bike is bone stock and I run T5's,my buddy's is the same stock bike and he runs T'6's. And to add I'm about 20lbs heavy'r then him

but I allway pull away from him. But if I every have to port my bike at least have 5's allready.

[MacRacer1]

anybody know the horsepower gains on either of these pieps

[03badazzbanshee]

OK t5 work better with mods and t6s work better with less modifieded banshee t6s creates more low-end and mid-range power the T6 is 8 hp over T5 on top end, and 5 hp over T5 on acceleration, thye put out around 55hp in the midrange. Both very good sounding pipes but t6s might be a lil louder but if u plan to do work to motor stick wit t5s .Hope this helps.
