I really like my BR2-1. Still in the process of fine tuning them in with my TTS. Getting closer, 'cause it's starting to run better.
But I like the sound, the throttle response and the looks. They just fit. I may take it west to Portland to someone that's been trained by Doc to use the TTS for a dyno run this summer. But so far so good with the tuning runs I can do.

I installed the big radius 2:1 (chrome) about 1200 miles ago and couldn't be more happy. Also have the SE tuner and SE air cleaner (not the heavy breather type). I also spent 5 hours of dyno time but it was worth every penny.
Sounds great. Looks great. Huge difference in low end, mid range. Take off in 1st gear, up to about 15 mph, shift into 2nd and jump on the throttle, rear wheel will spin. I weigh right at 200 lbs. I haven't noticed any better mileage but wasn't expecting any. It has a "back rumble" on decel but not a "pop". Again, it just sounds so nice, and I have the quietest baffle. (which is not quiet be any means).
I would buy it again. A few pictures in my gallery if you wanna take time to look.

I have had my Big Radius 2-1 for about a year and a half now and like it very much. I have a PC3 and K&N stage 1 a/c. I had it all dyno tuned and it runs great. Before I even left the shop, he said there would be some popping because the head pipes leaked (not tight enough). Rode home with some popping on decel and tightened up the head pipes, popping gone. Bike runs great. I will get the occasional single pop when I run the rpm really high in a low gear and let off the throttle, but otherwise not at all.

This is my bike, got also the V&H DRAK air filter, but still the OEM ignition setup, and it pops a LOT a deceleration !

Just a follow up...I went back to the dealer cuz the bike was runnin' like crap. My third visit regarding the tune...this time the tuner spent two hours with the bike strapped to the dyno and just maybe the third time is the charm. I'm trying to keep the Sideshots instead of changing exhausts.
The bike went from 69.06 rwhp/80.93rwtq STD to 74.00rwhp/85.00rwtq SAE and a noticeable "seat of the pants" improvement on my 4.5 mile ride back to the house. The popping is also alot less than before.
I'm gonna have more time for a longer ride Friday, but I think after three visits and a bitchin' session with the general mngr.
the tuner did a much better job with the bike.
I'm keepin' my fingers crossed they got it right this time.

When do you notice this popping? Just curious, I have short shots, paired with a Fuel Pack and hardly notice any popping at all, occasionally, when compression breaking, there is a minor deep pop, but no different than any other bike I have had, my CBR 900RR does the same, but again, not severe popping, Are these popping issues that I hear about severe, or subtle? Just never heard them myself on my setup..
