Mr. Adair

Anybody feel like giving me a quick tutorial on header setups? Pros/Cons of brands? You can keep it simple, I can do the research.

-Best value?
-Do NOT want to increase sound levels from what I have now (stock w/SharkWerks BP).
-If the side mufflers are removed for weight can the car be kept quiet enough?
-I need to retain CATS right?
-Benefits of long tube? Probably self explanatory..

This would be in conjunction with a sharwerks tune. And yes, I know they back EVOM products....

Thanks in advance!

Bypass + headers = loud. Very loud. If noise levels are a concern of yours, don't even bother.

Stock: Side and center mufflers = heavy and quiet, even with valves open
Bypass: remove center = louder, throaty sound valves still work
Side delete: no side muffler, has a center muffler, some setups retain valves and some do not. About same sound level as bypass, perhaps a little more quiet, lots of weight and heat gone
Race: cats only, no side and no center. Great for track, too loud for street [for most]

Side delete is my favorite for a DD.

Jumping on the band wagon from the OP...

Doesn't removing just the side mufflers create a dip in tq curve and potentially blow out your center muffler? I had read that a while back.

Thanks, that's what I was looking for..

I love the idea of a side delete. I'm guessing you lose the bypass and add center muffler back in? I do love the sound of my car as is with the bypass and if I can stay around that level or slightly quieter (but louder and better sounding than stock) I would be happy. I believe being able to continue to use a valve is also a plus. If I can make it a better DD that's also a plus. That combined with the headers would be a great setup. The issue as always is getting a chance to see or hear a set up like this before dropping the money. Nothing worse than getting 5K plus down the road and not being happy with the setup...

Mr. Adair

Thx. Always a concern when you stray from what the factory designed into the car of this level, definitely don't want to create an issue. Let's keep this thread going...

From what your saying, your searching for something that unfortunately you've already got the best setup for.

Side bypass, you will not be happy with the drone - WOT it's loud as well (probably similar dB but loud in a different way).

Long tube headers, even louder, so I would scratch that.

My recommendation would be, keep what you have (SW bypass is the best setup for DD, some added sound - the GMG and other style bypasses are louder than the SW). The only real replacement I see being suitable is a $11k option, Akrapovic Evolution system (full headers w/cats, rear and side mufflers).

Good luck with the decision.

IMO I'd say stay away from side bypass, go center bypass of a full exhaust system such as the Akrapovic. I had that setup on a non-RS 997.2 for awhile and it was an awesome sound (and livable on a DD basis).

Get the exhaust setup for some of the MN fall weather/scenery driving

Personally speaking, I like side muffler delete with valves. There is minimal drone and the tone is much throatier. If budget4 permits, I would go Dundon catted.

TheSilverFox

Agreed, Dundon catted with valved would be ideal, relieve the car of weight and heat. Currently have Dundon setup and first rate quality products. Perfect fitment which more than I can say for other aftermarket setups I have on other P Cars.....

Dundon = $$, but that would be my first pick as well. Happy with my GMG headers for the time being.
