Two Brothers or Staintune Exhaust?

Rick B

First question... does either one improve the performance or smoothness of the engine/throttle response? Do they make a Power Commander module for the ST1300 to match up with the new exhaust?
 
Performance like any aftermarket can, no. These are not track darlings anyway. I'm curious of the tone difference but be wary of questions of exhaust mods in this forum as the dusty ones will lecture with abandon. IMO the 2 brothers are made/sound well but the clamp looks cheap. The Aussie looks good but $$$$$. I had a Leo on my CBR without the Power Commander only because it ran so well but alas our choices are slim with a slow selling model. Good luck.
 
Check previous posts - the Power Commander won't work on the '04 and later STs. Since you can't retune the injectors to take advantage of the reduced backpressure, appearance and sound are the only changes. I'm not sure if the abruptness off of idle would be worse, or not; I'm sure it wouldn't improve, as you're running lean to start with. By the way, I stand proudly with the "dusty ones" - noise for noise's sake doesn't make much sense to me... It's a sport touring bike, not a race bike. Seven hundred and twenty plus pounds, but still fast enough for me and plenty comfortable.

Once again, noise was not the objective. Who suggested a ratty sound???? Why this one mod draws such ire is still a mystery considering the garbage some put on the quite nice ST. The ST is plenty fast for me also but "SPORT" is in the equation, no? We just disagree but there is still room for other opinions?
 
Indeed, noise wasn't mentioned by the original poster; the subject surfaced in the first response. The reason this mod draws such ire should not be a mystery. We all suffer from the actions of a minority who believe that it's their right to make more noise than necessary. Witness the periodic imposition of sound regulations, proposals to restrict the use of non-OEM exhausts, and attempts to ban motorcycles from certain areas. Yes, there is room for other opinions, including those of the "dusty."

The Turbo City 56psi Fuel Pressure Regulator will increase the mid range power and smooth out the factory lean throttle response.
Turbo Tom is a Vendor on this site, and will answer any questions you have over the phone or by email.
The stock regulator is set for 50psi. While you are under the fuel tank, add the K&N high flow air filter.
If you add the very nice sounding and free-flowing Staintunes exhaust, order the 59psi regulator. The fuel regulator are identical to the stock unit, and the Honda Dealer will not know that yours is set for a bit more fuel.

I've been running StainTunes for 2 years and I like them. They are not loud, but they do make a nice sound when you accelerate, quite when your cruising, just right IMO. I installed the pipes, K&N A/F, and Tom's FPR all at the same time and felt a much better throttle response, but I can't prove that.

My intent is not a louder exhaust, but a smoother throttle response. On previous bikes I've done (done by dealer) this to improve the lean/surging problem by adding a free flowing air filter such as the K&N and electronic module to increase the fuel flow and new exhaust system all working together to improve the overall performance/smoothness of the bike. I'm not interested in making it a race bike, as I already have a 1989 ZX10 for that need for speed situations. I just want the ST to run as smooth as possible and if it does come with a little more noise (good sound) with an emphasis on "little" that's ok too. Thanks for the IMO's, that what we humans are all about and that's a good thing.
 
Staintune and 60psi fuel pressure regulator smoothed my bike right out. I feel the throttle response is much smoother and slow speed manners are more comfortable for me.

Without the inserts in the exhaust the slip-ons are too loud for me (note-for me!) but I really like the sound with the inserts, from idle all the way to red-line.
 
I just switched out my Two Brothers with Staintunes I like the sound of the Staintunes much better not too load but with a nice low note..I had a set of D&D on my 97 Triumph Tiger and they were way too loud.
 
Turbo City only has 1 fuel pressure regulator and it does not say what the pressure is. Someone said to get one at 59lbs, but were do you get them?
 
I just added the 2 Bros and TC suggested going to a 60lb FPR with just pipes. He aslo said 61lbs if you add a K&N filter at the same timer as the pipes. I ordered a 60lb the other day and it does make a difference. At check-out you can specify which one you want.
 
Yes. Put the 2 Bros pipes on 2 weeks ago and the 60lb FPR the other day. I grimaced over the thought of installing it, but it was very easy. The air box screws came out very easily and the toughest part was getting the stickin' hose back on on the rear of the air box. Other than that, I took my time and it was a simple install. Follow the directions supplied exactly (don't jump ahead or bypass anything) and you should have no trouble.
 
And it comes with all the new replacement parts you need? I was reading the shop manual and it says that a lot of the hoses and clamps should be replaced with new one. Sorry for all the questions, I just hate being in the middle of a project and then realizing I need a stupid part that I could have ordered ahead of time.
 
Really shouldn't need anything else. The service manual is written from the perspective that you going in to change the regulator after a failure when the bike is much older.
 
There are only 2 hoses going to the FPR. One is a vacuum and the other is fuel. My bike only has 3700 miles so the hoses are like new. I'm a backyard mechanic and don't like jumping into something without knowing either, but this is really a simple job if you follow the directions word-for-word.
 
I ordered my Pipes on Saturday. If I am going to take the bike down to replace the FPR then I am going to change the intake to a K&N filter. Did you do that as well. I know from all my experience that when change the intake or exhaust you have to change the other one. When changing 1 of these you effect the air/fuel ratio.
