#415183 Spydr (User) Let's Ride ! Platinum Boarder Posts: 2252 Calling all Exhaust Experts 6 Years, 5 Months ago   Can anybody tell me the result of increasing back pressure in aftermarket pipes?

Moderator Posts: 22378 Re:Calling all Exhaust Experts 6 Years, 5 Months ago   Just depends if you have the baffles that came with the pipes then that is where you should be. If you have no baffles the it will increase your performance up to a point. If you go to far with back pressure then it is bad for the engine. Most pipe manufactures tune their pipe design for the best performance and noise levels. There are those of us that just have to screw with stuff.   Logged       The administrator has disabled public write access. #415187 Spydr (User) Let's Ride !

You and Erb and others are BAD influences I have the spiral baffles in the V&H's. Thinkin of adding small lollipops at the engine end of the baffles. Bit more back pressure = a bit more torque?   Logged     Welcome to my NightMare   The administrator has disabled public write access. #415189 Erbman02 (User) Platinum Boarder Posts: 7000 Re:Calling all Exhaust Experts 6 Years, 5 Months ago   I thought someone was talking about me, my ears were burning. lol A few yrs back, read some info on the net. Basically, the way pipes are built, inner diameter, baffles, length of pipe, all play some role in where the engine will get it's best performance. There is not going to be a pipe that will provide across the board performance. The more open a pipe, the loss of low end Tq, but better on the high end, unfortunately, our Tq peaks at just about the middle of the RPM range. Personally, I wouldn't add to an existing manufacturers pipe set-up. Maybe if you shortened the baffle, then added the loli's. But really, I would leave well enough alone.   Logged       The administrator has disabled public write access. #415193 Spydr (User) Let's Ride !

That's good enough for me. However...

Moderator Posts: 22378 Re:Calling all Exhaust Experts 6 Years, 5 Months ago   You can always do like I did and make your own baffles and keep the ones that are in there to put back in when you are finished playing. Matter of fact I have a half a dozen sets in the shed from my playing days.   Logged       The administrator has disabled public write access. #415197 fireman922 (User) Schrodinger's Cat - Wanted Dead & Alive Platinum Boarder Posts: 5845 Re:Calling all Exhaust Experts 6 Years, 5 Months ago   Erbman02 wrote: I thought someone was talking about me, my ears were burning. lol A few yrs back, read some info on the net.

Erb, Do you really think most of the pipe manufactures really throw the bike on a dyno when they are designing pipes? I figure they just sit down with a new box of crayons, grab the red one and start drawing over a photocopy of a picture of a Roadie. When the prototype is fabbed, maybe throw it on a bike they borrowed from a "friend of a friend" and take a rip down the parking lot. I'd bet a paycheck that less than 10% of pipe designs have ever been on a dyno before they are sold to the public. Of course I have been wrong before (today even...). edit: I'm talking aftermarket pipes.   Logged     Last Edit: 2011/09/01 17:24 By fireman922.   Ask me about my attention deficit disorder or my pie or my cat.

At first I didn't like the loss of Tq and I also lost a few MPG went from 52 to 47 MPG. I like setting off car alarms and seeing people put their fingers in their ears when I go by. So it was well worth it.   Logged       The administrator has disabled public write access. #415203 Spydr (User) Let's Ride !

So it was well worth it. Shit Lucky, I set off car alarm 'warnings' with the baffles in, and I usually don't 'get on it' hard. If i Goose it, I think all bets are off. If i take the baffles out, the noisy Bastard would annoy ME! Kinda hard to 'Talk' to the ladies too, when you're makin all that damn noise.   Logged     Welcome to my NightMare   The administrator has disabled public write access. #415219 onry (User) Senior Boarder Posts: 397 Re:Calling all Exhaust Experts 6 Years, 5 Months ago   i need to make me a decent set of baffles just to tone her down just a shade. Doc told me a couple of months ago that i need hearing aids to correct tenitus(ringing in the ears) i tried the lolli's just not quite deep enough rumble still a lil too high pitched. i like settin off the car alrms in parkin lots tho too   Logged       The administrator has disabled public write access.
