V and H Big Radius 2 into 1 : V-Twin Forum: Harley Davidson Forums

xxx · 11-30-2007, 11:34 AM

Has anyone tested the V and H big radius 2 into 1 exhaust? I would be putting them on a Fat boy at about 100/100. How do they perform? Any information would be helpful. How would they compare to the Propipe or a set of FatCats?Thanks

There were 2 or 3 threads under this heading (exhaust) but I cannot find them in search. One was elephant snout and the others were similar to your heading. Forum has crashed or had trouble and maybe some data was lost.

I have just an 07 96" with stage 1 a/c and pipe tuned w/sert at Dealer. I got 72 HP/84.5 TQ. The tq curve starts at 2500 and immediately shoots up to 80 tq and climbs to peak tq at 4000 then slowly drifts down at crossover at about 5300 rpm. Tq is at 72 there.

There was a guy here under 1 of those threads I cannot find that had 110" SE and his did real well. Same steady flat, no dip tq curve as I got. There are alot of fanciers of the Pro Pipe and FatCat here (also the LSR and some others) so they should chime in soon. Maybe someone who can search better than I can find those other threads. Oh ya, alot here hate the pipe but who gives a sh$t.

Hey GrampsWyatt, now there's some good info there ! I'm going to pull the trigger on my purchase.

check out my post streetbobs with drag bars, ranger bob has one and says he gained 10 hp. looks good on his bike.

Like mine. Sounds good.
I wanted something that was a bit quiter as well and am happy with the low deep note these put out. Bike performs well with them on.

Regards Greg

Anyone have any actual dyno sheets they can post with this pipe??
I've heard a number here and there - but Id really like to see the curve . . .

No scanner but a picture, hope it works.

Ohhh yeah - Thanks Gramps!

That's what I call a nice 'curve'!

have it on my DWG. I love the look and the deep rumble. I looked for the dyno sheet but cant find it, I think wifey threw it out!! With a hypercharger pro-r and a T-max I picked up 10 hp and 12 ftlbs over stock. Took it to 90 ftlbs and 78 hp. Runs great great.

Have to say that I have had a dislike for 2 into 1`s eversince and have always stated on here these these things look like boat anchors and will end up hooking you up on parked cars etc.................

Buuutttttt I just followed a fatboy home the other night and the pipe looks bloody lovely and the sound is THAT sound that all of us love and want.

I dont have a ride at the moment, tried to get on the drip with a new purchase of a Rocker C but according to the local stealer, production has stopped on these and they will not land until June in Oz so if I can sell the boat then I will get a new fatboy and try one of these pipes.

All the best, Ozzie
