Please give a full review when you install the Dundon exhaust. Love to hear your opinion on the difference between the two.
Thanks

You dog! Cannot wait to hear that awesome setup.

I was about to order Akra center bypass today. And before confirming an order for the Akra I got in touch with Kline just to learn what they can offer given that I had it on my 911 turbo s and liked the exhaust.

An offer from Kline is as follows:

- they offer their center section + their headers with valves identical to OEM valves (same brand, same model)
- they keep the OEM cats, OEM manifold with all 4 OEM lambda sensors
- everything is made of inconel 625
- as a result they promise no drone, no CEL, no need for remapping the car and the sound will be louder than just the center muffler delete but will not be annoying (as per their statement)
- huge weight savings given that the side OEM mufflers are gone

I have to say, they price for the above is really competitive.


Now I am thinking which way to go - Kline as per above or the Akra center muffler bypass only


here is the center section from Kline, which they recommend for this setup
unfortunately I don't have the picture of their headers, which keep the OEM valves

I did not see a CAT header on their site? Looks like a non cat long tube available thought.

it is a custom made thing. they are not normally producing it.

Alan C- looking forward to hearing your feedback! Will likely pull the trigger on the same setup if it provides you aural bliss, not to mention palpably increased power. Currently with Akra CMB (valves open)-

Dropping the car off at Porsche of the Village tomorrow and picking it up Thursday afternoon.

Best weight savings / bang for the buck: side bypass with valves into RS muffler. Zero drone and smooth Porsche sound, amplified

I was originally running the Soul Competition setup and found that to be too loud. I was almost embarrassed driving it around.

I now just am running the side deletes with stock muffler. You can't go wrong with either a center bypass or a side delete but with both it gets extremely loud.

If you want my Soul center section I'd sell it for $500 to just get it out of the garage.

Who is making the best quality side muffler bypass, so that it uses valves and OEM cats so that there is no need for remapping and there is no CEL.
And that the above is combined with the OEM center muffler.

As I am thinking about this option as alternative to center muffler bypass.

It's Thursday afternoon.....what taking so long

I don't see much difference between the various options other than price, which varies widely. Side deletes are the best bang for the buck IMO.

and what is a better solution in terms of keeping the Porsche warranty? Side muffler bypass or rear muffler bypass option?

as long as its cat back its immaterial...

Dropped the Dundon parts and stock mufler off at the Village. Got a call shortrly after informing me that the studs on the stock muffler were either stripped or broken off the muffler.
Last night I removed remaining studs and drilled the locations so I could put bolts in their place. Dropped the muffler off at a shop this morning to have the bolts welded in place.
Just now received a call telling me to bring the car in. Since it's raining in Cincinnati I may only have a pile of rust by the time I get there.
