In general, assuming AC and SERT mods as recommended, how much TQ/HP difference between a good set of slip-ons vs. true duals or 2-1? I'm still debating the power/looks/loudness factors.....the 1000 mile point is fast approaching and I need to figure out my game plan. Let's hear from the exhaust pros! Thanks!

Rineharts...my first and last choice. Next set I use on personal bikes will be #10.

FWIW.. Just got my 04 SEEG back from the shop. We Dynoed it before we split the cases and dynoed it again when we put it back together.
This bike had a thunder header on it when I bought it. The noise gets annoying on long trips. I had a Screamin Eagle

Mine had the oil leak showing between the engine & trans, and on the bottom of the motor. I got the cases split under warranty to fix the leak.
Thought I'd try to quiet it down while we had it apart.
I'll run by the shop after the holidays (Tuesday) & see if I can get copies of the before & after dyno sheets to post. The only mods this bike has are the S&S 585 gear drive cams, the cometic head gaskets, HD High Flow AC and Race tuner.

hd-dude · « **Reply #6 on:** January 01, 2006, 08:06:37 PM »

Alazo;
Those numbers are low for what you have. others here with the same mods without the cams are reporting better numbers than yours. Do you have the race tuner or PCIII?

Also concerning is the S&S 585 cams have a .585 lift and the CVO 103 heads only have springs that will handle a .550 lift

Alazlo · « **Reply #7 on:** January 01, 2006, 08:22:43 PM »

This bike has the race tuner... Bought this bike used with about 3500 miles on it. Only got to put about 500 miles on it before the bad weather. Gonna ride it this way for a month in Florida and evaluate it. My last bike was 80 hp so the step up to 100hp may satisfy my needs for awhile. Engine was built when I bought it. I know the previous owner & the engine builder. My tech says the S&S cams are the reason for the low numbers has suggested LeinWebber cams. I have to assume that the springs were changed, but will find out Tuesday.

One pipe for performance on a motor under 113ci "THUNDER HEADER" You can say what you want but any two into one will out perform and single dual set up hands down. On your larger motors D&D Fat Cat. I have no personal experience with them but Zippers swears by them.

My personal experiences would suggest that Thunderheader is the all around best performace pipe for a wide variety of engine sizes and types, BUT the noise is more than I can take and in some states attracts the law in a huge way. I'm on my first set of Reinharts so I don't have a lot of experience with them but I can say they perform well, run reasonably quiet when you stay off the throttle and open up nice out on the road. All in all a great combination of performance, noise abatement while still retaining a nice sound and most importantly a quality product.

With the only mods to my SEEG being just a SE Air Cleaner Stage 1 kit and SE Race tuner my numbers were only 95.1 HP and 98.1 TQ with the D&D 2 into 1 pipes.
To my surprise when i swithched to the Rineharts my numbers were 94.5 HP and 99.0 TQ. my torque was higher with the Rineharts but i lost about a 1/2 HP.

If you're staying at 103c.i. I agree with The Dawgs statement. You could also look into the RB racings 2:1.
D&D makes two versions of the 2:1 Fatcat, (the fatcat Borezilla is made for 103 and larger c.i. with Heavy engine mods.) If you're staying at 103 c.i. with bolt on mods the Borezilla would not be the pipe for you. D&D fatcat, Thunderheader, RB racing!! [highlight]The "NEW Rinehart 2:1" would also be worth looking into.[/highlight]

Good luck in your search.

Take Care,

Grover

You may want to wait on the Rinehart 2:1 (if you are running a bigger then 88ci motor) at this time as this was a post from another thread.

Alazlo, you need to find a tuner that knows how to tune a Race Tuner because these numbers are low......especially for what you've got.

Listen, I have a stock motor, cams, etc. I just have the Screamin Eagle High Flow Air Cleaner, Race Tuner and Vance & Hines Pro Pipe and I'm pumpin 100HP and 104 Ft. Lbs. of Torque.

HD Tech line advised that the original 251 cam in my bike had a lift of .579. The 257 & 258 cams are .580. . They advised that the stock valve springs in my stock 103 heads will handle the S&S 585 cam with no problem..... According to HD Tech the .550 lift discussed here does not apply to the 04 stock 103 heads...

The CVO 103 motor does not have a 251 cam., It has a CVO-253 cam with a lift of .538. I'm not sure who told you that but they have given you wrong information.

[highlight]Edited, The lift is .538, I attached the cam data from the SE cataloge as well[/highlight]

Big Time · « **Reply #17 on:** January 03, 2006, 03:44:54 PM »

I too question the .550 lift info. I just had my stock heads checked for clearance as I am adding Head Quarters cams with .580 lift on the intake. The springs in the CVO heads appear to be the exact same ones as in the HTCC non-ported heads. They are double wound with a damper and are quite different than the stock Harley springs on a 88 motor. We checked valve to valve and valve to piston and both are good to past .230 lift at TDC. The springs didn't coil bind at .600 lift either. We just cut the guides down a little to be on the safe side. The next time I'm in the shop I'm going to check the part # of the springs in the HTCC and the part # of the CVO springs.

A call was made to the factory some time ago. The factory stated that they were good for .550 lift. It may be that your set will take .585 but you need to remove them to check them. This is where all this has gone. A lot of people don't want to remove their heads. Now the 103 plus heads on the other hand will handle up to .650 lift. So the best I can tell you is if you are going over .550 plus maybe 10 more you need to check. I can tell you for sure that your valve to piston and valve to valve clearence will be fine with the S&S 585.

Final, short, post on the subject. Spoke with the Factory Tech line again today . Spoke of cams, part numbers for springs ect. Bottom line, for the third time, a third HD Factory tech advised that the S&S 585 cam would be fine with the stock 103 springs, valves & heads. The bike has had 3500 miles put on it with these cams & it's been ridden hard. I'm gonna go with Harley & when the motor comes apart I'll let everyone know...

the O`Fender · « **Reply #20 on:** January 11, 2006, 11:38:17 AM »

The SE parts catalog only lists 1 set of springs with a damper, the part #18273-00 is for a "set" of 4 springs, the parts catalog for the SEEG stock heads lists the springs as part# 18272-00 for 2 springs, the local service writer near me made calls to MOCO and was told that the 18273# was the correct replacement parts for the complete set!!!

Thank you very much 'Fender. You may have solved the biggest riddle on this forum! This will for surely answer alot about "Bolt-in cams".

what's the consensus on Hooker True Duals ?

An un-indited co-conspirator of mine is running em and talks em up louder than they sound and the suckers are loud

fatboyse2 · « **Reply #23 on:** January 12, 2006, 09:52:43 PM »

Stick with Thunderheaders for the best performance. I tried several pipes, shotguns, SE 16 Gauge, and Thunderheaders and without a doubt, the Thunderheader performed much better and sounds great. A bit louder than the previous two.

SPIDERMAN · « **Reply #24 on:** January 12, 2006, 10:16:46 PM »

I don't want to buy anything I have a set of Reinharts and love them. Yeah I know about Thunderheaders, I had them on at least three different bikes, but have decided to quiet down a bit.

[size=14]My post was that a buddy has Hooker True Duals and goes on and on about em and I was wondering if anyone knew anything about them . [/size]

Anyone have experience with the RB LSR 2-1 2" with the O2 sensor? I am thinking of pairing them with a Twintec closed loop FI setup.

geezerglide · « **Reply #28 on:** January 13, 2006, 01:27:50 AM »

ceej,

I would look at the RB Racing Black Hole 2:1, it is longer than the LSR goes just past the saddlebags and a lot quiter, however, still as good.

Apitbullpappa was selling a set of the LSRs, look back in the Selling Post to see if he still has the pipes.

Ceej · « **Reply #29 on:** January 15, 2006, 10:14:01 PM »

I wonder how quiet the blackhole is? I currently have V&H Oval slip ons & am trying to talk myself into the black 2-1 --- I think it would look good on the pumkin but It's been years since I bought a part that wasn't chrome - don't know if I can bring myself to do it!
