I'll need to add a storage shed to keep all the replaced parts! What do you do with a spare CAT - spray paint it yellow and use it as a boat anchor?!
I'm keeping mine because a bill just got shot down in the state house for making us smog our bikes - if that day comes I will have to put the cat and stock pipes back on - probably go get the original tune put on so I can pass smog - and then put her all back the way I like - ugh.

A few years back I was doing some dyno tunning with my kawasaki and at the time some of the guys in the club were having a big debate on filters. So I decided to do a back to back comparrison of the bikes performance with the factory filter (a foam filter similar to the uni) and the K&N aftermarket filter.

The results supprised me as the bike made more power with the factory foam filter than it had with the K&N.
This wasnt one of those one run with each filter tests, I did multiple runs with each filter and made changes in the jetting and even ign advance rates. It just was that everyting I tried the factory filter outperformed the K&N.

I also used to do a lot of off road Dune buggy rideing and racing.
After a few years of dealing with dirt somehow getting threw the K&N a fellow off roader suggested I try a set of Foam on Foam filters from CB Performance. Once installed at the beginning of the season it was the first year I went the entire season without having to clean dirt out of jets. Not to mention that half the time I could get away with only cleanning the outerwear of the filter. Not to mention that I could clean both filters (dual carbed) in less than an hour and be running again.

So you guys can probably guess what filter is in my tthunderbird?

As for what to do with stock exhaust. Any part I take off gets packaged nicely and put away. The cost of replacement if something happens can be high. Not to mention if your like me and keep your bike for a long time you have to remember that as the years go on they wont be making aftermarket parts for it so replacement of those hog slayers might not be an option in 10 years and as with my kawasaki 900 the factory exhaust is no longer availible and the only option is to have a custom made set done at a big cost! Some guys in the zl club would pay serious money for the pipes I have neatly tucked away just for in case. Not to mention If I decide to sell a bike having all the stock parts actually improves you value and gives you the upper hand when negotiating.

When I go to buy a used bike. The offer I make for one with an aftermarket exhaust is always considerably less than what I will pay for one with all the factory parts/pipes. I really dont care who made or how good the aftermarket pipes are, if the stock pipes are not present the bike is worth less!

Greetings,

This entire thread is very interesting... to the point where I consulted my local "expert" Paul who has been working on metrics his entire adult life... He is also the guru on the DYNO at our local dealership.

Now he has never tested a TBird but has tested several other bikes on the DYNO, Goldwing, HD Big twins, and a couple other crotch rockets... He's done the tests with stock filters, K&N and another "SHOP" brand (foam) that they use... All but the older HD's were EFI's.

His results are pretty convincing, that unless you have an aftermarket control module (like the Power Commander) and put the bike on a DYNO for a custom tune... The difference is negligible... He said the biggest change was with a Goldwing and he was only able to gain a couple of HP and probably improved the gas mileage. The other bikes improvement with stock tunes were barely measurable... except for maybe MPG... while some improved and others were less.

So having heard Paul give his professional opinion leads me to believe that unless I have to replace the air filter... it is going to stay stock... Then I will replace it with something respectable but not over priced....

To each their own... and everyone has their own (opinion).

My feelings exactly. The main reason i have a UNI filter is that when you use a stock filter you never know if the bike is suffering from a restricted airway due to the filter being impaired. With a reusable filter any time you are thinking it could be, you just clean it and instant piece of mind !Not to mention the savings. A stock filter costs about the same as a UNI. By now i'd be on my 2nd or 3rd one. If 3rd then i already saved $60.

Now if you intend to do major engine mods thats a different story.

Greetings,

Can anyone give a part number for the UNI? dasco, you make good sense, I guess any reuseable quality air filter is the way to go...

UNI Filter - 1011-0239/NU-3008
As seen on www.fasteddysports.com You might save a dollar or two if you shop really hard - but we like FastEddy, he bends over backwards to please and I got mine quickly. I always check his website first when I need something and by the way - if he doesn't have it - email him - because he is expanding, and he might be able to get it for you if you ask. I bought some Triumph shirts and whatnot and they didn't have the color I wanted and he decided to add that color as well as a few other options.
