Do you have to take this into a muffler only shop, or can a mechanic type shop do this mod?

 

Do you have to get this done at muffler shop, or can a mechanic type shop do this mod?

 

A good welder should be able to do this. Provided they know what they are doing. Mine was done at the dealers during an oil change visit.

anyone in the Dallas/Ft. Worth aree have this done? Im looking for a rec on a good shop...

 

Im not really finding anyone who has done the one ball set up but changed the muffler to a magnaflow or borla or similar..... Anyone with any luck going that route? I figured run that but keep it on the passenger side for better weight distribution with a driver in the car.

 

your talking about a single sided system, just reusing the stock pipes.

 

yeah, i just cant find any info on it.. on how loud to expect it to be.

 

I did the one ball Mod now maybe a year ago. kept the stock "ball". I have had experience with Borla and MagnaFlow but not on the mini. Both companies make different muffler models for different applications. I am sure you could call them and they can help you find something in the sound range you are looking for.

If you get one made for a different car just make sure the dimensions will be right but in the end you will be doing more welding than it's likely worth right? You will need the tail weld for exit, a hangar, and the inlet weld. One ball stock rocks but I am waiting for the dreaded drooping I have read about w/o that second hangar support. I'll ride it 'til it drops...

 

for a different spin on the one-ball, I upgraded the pipe from the cat all the way back with 2.5" ss. Installed a OBX header and a Magnaflow 2.5" cat. Still used a stock muffler on the left side. It's been a little over a year now and still sounds good.

 

I got a 2.5" Borla Pro XS in the mail today, monday im gonna cut the stock system off in front of the first muffler and adapt it to 2.5 and just put a turn down at the end of the muffler.. guessing itll be LOUD but hopefully a nice deep tone.

 

I got this mod done yesterday and I'm very satisfied with the results.

BUT, exhaust tip is shifted to the left side...I think it's because the weight of the right ball is gone.

I've looked under the car and noticed that I can't do much because the left ball is just hanging there with a rubber attachment. I can't center the exhaust just by pushing it because it just returns because it's just hanging there.

Anybody else notice this problem? If so how did you fix it? How WOULD you fix it?

 

Sounds like the shop didn't quite get it back together right.

 

Is your new pipe elbow bolted in with clamps or welded? If clamped, maybe one of the 'legs' of the pipe is a little long. You might be able to loosen the clamps and adjust it. If welded, you might be stuck unless you want to cut one weld and adjust it. Obviously, center the tips and hold in place before re-tightening the clamps or re-welding.

 

Are you asking me if the new pipe is welding or bolted to the body or to the rest of exhaust? I'll have to go check

 

Seriously considering this... I wonder if Helix has a mandrel bender?

 

I don't have that problem take it back to the shop and tell them to correct it...

I wouldn't even worry about it. It is a cheap mod and it not being mandrel bent is not going to affect performance on your car.

 

A poor bend and offset transitions can create more backpressure than removing the right side resonator reduces. I’ve seen some bad hack jobs that are not only restrictive, but sound terrible too, because of how the crimp alters tone (think can-of-bees). One of the main advantages of using the pre-fabricated MinSpeed resonator delete tube is flow-pleasing bends.

The one ball can become a better performer by replacing the OEM flange end piece,its tubing necks down to less than 2 inch ID 1.5 inch past the two-hole flange, a 2.25 ID section of tubing on an aftermarket flange is far less restrictive. For the daily driver, the sound is easier to live with if the replacement flange is incorporated with a resonator. The sound from a straight through perforated resonator and the chambered OE muffler is very nice.

 

Huevo,

Can you elaborat e on your last post? I'm afraid I haven't understood what you said, but increasing flow is important.

 

It should be noted for everyone doing a "One Ball Mod' that a hanger rod be fabricated on the passenger side to bring the pipes back to center, and to help support the system!!!!!!!!!!!!!!!!!

The resonator that was cut out of the system had one Only makes sense to put one back in yes ?

 

I believe he is speaking of the prefabricated pipe bends are "crinkled" at the elbows....as apposed to a piece of pipe bent in a machine......most shops like Meineke have the machine to bend pipes but some do have 90 degree pre bent sections which have the crinkle elbows which would be considered a "hack install".

 

never had this problem with mine. The 2 hangers on the single muffler is more than enough.

 

Minspeed resonator delete tube, a good bend.


New flange and resonator attached to one-ball.


Bad bend example in the attachement, that bend deforms to less than 2 inch OD.

 

Eeep. I cringe when I see my old exhaust. I hack job indeed, and the guy burned my heat shield with his torch to boot.

 

Can this be done on the r56?
