Planning an exhaust upgrade without having to chop and change is the ideal situation as it saves hassle and the expense.

People are buying loud rear silencers (race versions) first and then when they want more power they are plagued with an insane amount of noise which they are almost forced to live with. They convince themselves it's all ok and they love the loudness but really they don't and as soon as money becomes available you see a quieter exhaust setup appearing.

Always buy the X Pipe first or just do the test pipes and a rear silencer.
If the final few HP is required or a little more noise then the entire X Pipe can be changed.

yes it would if your looking for a valved setup.

your right, i had the race muffler when the car was still under warranty, as soon as my warranty was up i dropped a full system and a tune. Loud is nice when you can control it ( valved )

The reason I went muffler first was because I did the OEM exhaust mod. At $300-ish, it makes perfect sense. Then the mod bug bites and before I know it here I am with test pipes.

So yea I went back with quieter exhaust. It's an expensive game haha

OP, that sound is pretty intoxicating. I am wondering:

1) What are your thoughts on the in-cabin sound change? Is there a significant change over OEM?

2) Do you have, or can you make a video from in the cabin with windows up, and down?

Great review, and truly love the sound from outside!

Windows up the Akra is almost the same as stock. Windows down you hear it but you can easily have a conv. or listen to the radio. The Akra has a much deeper sound down low when compared to the oem muffler with pipes. As for the Gt2 with pipe, it was loud 99.99% of the times and it droned inside for the most part. ill try to get a cabin video for soon

Nice videos! Recently I had my iPE mufflers swapped to stock while retaining iPE x pipes. I think I lost some low end torque with my current setup. Now, I am thinking to use the stock X pipe with iPE mufflers.

my exhaust history with S65:
1. stock was too quiet
2. Akra evo added power and torque but droned pretty bad in the cabin
3. iPE F1, it was just SOOOOO fricking loud but it was okay with valve closed but I lost torque on low RPM
4. I had iPE did a custom job on the x pipe, it improved torque. it was either pretty loud or murmured.
5. iPE x pipes with stock mufflers, I have no clue what are the cat flows or resonators.

I have really consider going back to full stock as I have no clue which setup gains power or loose power. Perhaps I will regret it being too " quiet ". Please help me out! The only mod I have is the exhaust.

You cannot lose torque going back to the stock rear section over a design such as the IPE.

Akrapovic EVO can only really heavily drone inside cabin upon incorrect installation where the X Pipe slightly touches the exhaust support or is under too much tension.

Your best option if you want a very quiet life is a very high quality X Pipe with resonators + high flow CATS and your rear stock exhaust
OR
Properly designed primary CAT delete pipes with a very sensible high quality rear mufflers like the Eisenmann Sport, Evolve E-Tronic, Dinan, Akrapovic Slip on.... etc.

decisions... decisions... I'm wanting to add either the Dinan X-pipe or Akrapovic X-pipe to match my Meisterschaft GT to make more power.

I have a feeling I'll think it'll be too loud and will have to make the decision of
a) loving it (optimal)
b) reverting back to the stock x-pipe and keeping the Meisterschaft GT (less power but retain Meisterschaft sound)
c) buying an akrapovic muffler and keeping the dinan/akrapovic x-pipe (retain power but lose the Meisterschaft sound I love so much)

i was running a GT2 which is a totally different story. I think a GT with HFC in the primary position, like Gintani or fabspeed wouldnt get too loud, and you will get nice gains. If you want to go full catless, go with something with quad resonators, like the Dinan or the Gintani. Challenge sport or Akra is another option but i think the GT would sound much better with HFC in the primary position. Another thing to note, you will need adapters to fit anything to an Akra x-pipe, which are pretty hard to find.

Garage List
That GT2 was very loud.

I went from loud to very loud and again very loud, settled with quiet now.
1. Eisenmann Race. Sounded pretty good and i liked the tone. But wanted MOAR
2. RPI GTM. Very loud, most power, but lots of drone and the mufflers hang too low.
3. Gintani race. Awesome sound. Very deep and throaty. Big tips improved look but even though it was resonated, it still droned badly.
4. Akra Evo. A bit too quiet but no drone at all and gives you lots of power. Happy girlfriend mode

What's the most mellow setup with the most gain? ( especially low end torque ) I had Akra evo and it droned at low RPM and a dip under 3k RPM

i actually think Akra with challenge sport sounds awesome! drone is basically none existent, sounds great when you push the car.

you will always have a dip in torque when removing the front cats, get a tune to take care of that dip and gain some power.

Upload it on Youtube.
I was shocked at how quiet the Eisenmann Race is. That thing was quieter than my ACM exhaust mod.

Everyone also said catless Eisenmann Race would be too loud and I assure you it's not! Under 3k, it's absolutely mellow (windows down, I can hear music no problem). Go over 4k with heavy throttle and it roars.

It's seriously amazing how this exhaust can be so tame yet so exciting at the same time. I finally found my perfect setup.

Damn I wish you had clips of the oem rear and challenge sport... I'm really considering that route as I have the oem mod (perf. Method) and want a tad more sound with the benefits of removing the primaries. Every vid I've seen so far makes this set up to be prettyyy loud but I'm not sure in real life. This is my DD.

i ran a stock muffler without the mod. i would guess it would be really loud in a bad way.
