I got installed dual magnaflow performance mufflers on my 2011 GS sport. Cut off the stock ones and welded Magnaflow on it....It sounds deep low pitch ...

post up a vid , teasing isnt nice

terapio · July 8th, 2011, 04:40 PM

will do later on today ....

tronghoang · July 10th, 2011, 11:06 PM

Please do so. Cause that's exactly what I was want to do!

tronghoang · July 10th, 2011, 11:06 PM

Oh, and how much did it cost you?

DustinH · July 10th, 2011, 11:53 PM

Bump for video!

terapio · July 10th, 2011, 11:58 PM

shop charged me only $100 to weld both mufflers and mufflers coasted me both of them around $125...... so over all $225 not bad at all....and i will have the video soon ...

Will just adding mufflers help hp or do you need a full set-up from the manifold?

Gains will be minor if at all, it's for if you're looking for sound. Cat back will get you gains, but full exhaust is optimal as long as you're running good size piping.

How much gain will you get out of a full exhaust system without changing manifold and headers

Thats exactly what I always have wanted to know. Never get a straight forward dyno answer

terapio · July 11th, 2011, 11:00 AM

Gains r minor but sound is great.....and i noticed car picks up quicker now too than before.

muscles · July 11th, 2011, 11:19 AM

If you do a straight pipe from the cats to muffler you will feel minor gains. The point is to do intake, exhaust, and header so they all add up together. For the gs with those you will see up to 170 to the wheels I believe.

terapio · July 11th, 2011, 11:21 AM

for 2011 it is straight pipe to mufflers.....and i have cai in too.....so it does improve a little..

MACH1219 · July 14th, 2011, 07:48 AM

do 2011 GS's have 2 factory mufflers? Or did you Y out the tailpipe into duals?

terapio · July 14th, 2011, 09:22 AM

It has 2 factory mufflers.....

Clovisman · July 14th, 2011, 02:40 PM

All most evey car these days comes with a factory RESTRICTIVE muffler installed. Because you have a dual exhaust I can't confirm the HP gains by installing a performance type straight through muffler. But with the single exhaust setup, just changing to a performance muffler we gained between 5-10 HP without messing with the rest of the exhaust system.

Even with a CAI and headers installed, it is not necessary to change out the stock exhaust system, the stock exhaust handles our flow very well, it's our muffler that is restrictive and will provide gains if swapped out with a performance staight through type muffler.

Now, because our dual exhaust system is not a TRUE dual exhaust system, gases will take the path of least resistence, period. When those gases meets resistence like one, or the other OEM mufflers, it will create a back pressure and push the exhaust out the other pipe. But the only real purpose for our dual exhaust is purely for looks, in-turn to open your exhaust you have to spend twice the money to fix the flow problem.

dejectedangle · July 14th, 2011, 03:11 PM

The pipe stock is only 2 bends same as the injen magnaflow greddy... So ya it's pretty much just the muffler that is restrictive..

MACH1219 · July 14th, 2011, 04:03 PM

I never saw a 4 cylinder with factory duals before. what year did they change it? my 2.4 has one muffler. Im talking exiting out the back of the car, not the secondary resonators and stuff in the same pipe as the one muffler

I think they started in 2010 putting in a two-muffler system on our car... remember, a true dual exhaust system has two independent exhaust systems running from each bank of the engine, not a single pipe that splits to two mufflers. Our two-muffler system is purely for looks, not for performance!!

terapio · July 15th, 2011, 01:15 AM

should i take out my resonator or not?

I know what a dual exhaust system is, thats why i clarified i was talking about mufflers that were split in a Y pipe (or at least i wanted to

). And i hope i was clear I was asking about the GS. I see you have a GT.

Are you still going to post sound video? who installed it, do you know if Midas or Merlins does aftermarket perf. exhaust and do they stock all the parts?

terapio · July 15th, 2011, 09:22 AM

some private shop installed it for me and yah just been busy but will have the video up tomorrow......midas install after market parts at some locations but they charge above $500......

Yeah, I understand. Didn't mean to sound condescending but there are other members who might not understand the concept. I like the look of the dual tips, but it's not worth the money for me to install, and for the folks that do have the stock setup, it just means they have to spend extra bucks to get it fixed.

Why did they have to cut? I thought they have the axleback system that just bolts in like this:

Search and See thread for; RRE-Axle-Back Exhaust, This guy installed his mufflers in 30 minutes(no cutting or welding) and he didnt even have to lift the car..

terapio · July 15th, 2011, 11:24 AM

oh because the mufflers had to weld it in.....it did not come as axle back setup...

Ok cool, I just Emailed Joe at ACI to see if they make a dual axle back set-up or if I just have to buy 2 of them for for my 2011..

How cool is the sound of yours? It doesnt sound ricey like an old civic, I hope?

terapio · July 15th, 2011, 12:19 PM

it does not but i will post a video clip of it soon...maybe today or tomorrow..... what you guys think for taking resonator out?

terapio · July 15th, 2011, 12:21 PM

and whether it is easy to take it out?

AndyWong · September 18th, 2011, 01:55 PM
