Putting all your advice to good use
Over the next few months I'm putting everything I've been planning - with much help from RL and the 996 crew - in place.
Started this week with the easy steps ... And will stay pretty easy for now as the RS has all the good stuff already in place:
ram air scoop, LWFW, some CF weight saving, Recaros, Harnesses, roll cage to be exact.
My approach is do stuff that saves weight, saves wear and tear - bigger brake ducts;
keeps up with new OEM developments - rad tilt, throttle body;
is either easily reversible, invisible or properly best of breed
so that you wouldn't want to reverse it anyways.
What's coming? Well started off with OZ allegrita which have arrived and
will be laced up with Dunlop slicks when I pick them up next week.
But for today here's the before and after:
Decat, x-pipe manufacture and fit.
Hope those of you who have kindly advised me find this to your approval
Thanks to Luzmore Snr for leaving aside his real work to make the x pipe to spec
And polish them! Will weigh cats but feel like 5kg each. Sound of the exhaust is only slightly different so that's great. No warning lights.
It's the massive/heavy side-mounted mufflers that hold the big challenge it seems.
Drive tomorrow after fitting the handmade fiberglass brake ducts - front and rear
- moulded off originals but slightly less high to allow for lowering later but they are
longer which should increase catchment and make them slightly less flappy (and cheaper to replace).
Glue also drying on front bumper mesh and under bumper hole coverups. Will check back in w more shots of anything interesting.

First couple of pictures don't show up, do they show the x-pipe in more detail?
It's tough to tell where / how the pipes merge from just the 3rd picture. I'm assuming you stuck with 2 1/4 tubing for the center section?

hey Audi - I resized the shots - work better now? the OEM pipe is 57mm (2 1/4) and I used a 63mm to get over that as the matching size with a sleeve over it looked funny.

Guy - I realised that over the last day as we got to actually removing the pipes. No kidding! But the heat and sounds issues are still key to me so I'll await your proof of concept in the form of a driveby vid or else I'll pop in next month to hear it for real.

My side mufflers have been replaced by much smaller more lightweight ones - but at high rpm they don't constrain flow much.
Wait till you feel what the headers weigh... I think they are lead lined...
Best you pop in - beer is on me.

Straightpipes/muff bypass /resonators- its freaking loud!!! Wouldn't recommend if u drive on the street plus u do lose some low end Trq. Driven my friend's 6gt3 with muff bypass- so loud neighbors filed a complaint. Find some lw side muffs to match catbypass- pretty good weight savings just doing that. 20lbs using catbypass about 20-25 lbs with lw street muffs. If u got no sound restrictions at your home tracks just buy some muff bypasses and put them on for those trackdays- it's freaking loud!!!! Mike

Hey Mike - I know what you mean - going to stick to some thing streetable, but the cats had to go and sounds really is only a bit deeper on idle and during rev up at low end although have yet to drive but sounds good to me. Guys got a pretty neat looking system - must weigh 20% of mine!
Cheers Guy - looking forward to it

Catbypass is fine with stock mufflers- I pass ls (92db) easily. I was running it like that for 6 months- u mite get a cel on steady highway cruising but doesn't affect drivability if stock o2 sensors are in stock locations. No big deal- I have airbag lite on for 5 years- too lazy to reset. Just get a cheapo obd2 reader that resets it. Mike

ahhhh ..... work, right
well I've been getting some 'work' done too and as I said sticking to the easy stuff but its been an awesome week! So far I'm on track and after a few tests today I'm glad to say changes are pretty sweet and working well. Scientific tests tomorrow but 4 or 5 pulls show the car is .5s quicker 0-160km/h although same 0-60 ... which shd be a few secs on the track .... which is nice
So here's the OEM (massive) fire extinguisher fitted ...
the SPR Racing pedals - grid - in
with the new colored stripe - nice Job Brian, perfect match - thanks!
K&N filter in ...
and 997 throttle body too ... thanks Divan!
with all caps wired per local track spec and auto door lock on drive-away de-programmed
and topped off with the mesh in front bumper and covering up of the holes under bumper to increase downforce. I set the mesh back so black hole look remains.
and also I put my numbers on too - not 'Megan' ... but getting properly sorted.
I could keep going tho its late but I've gotta save something for the weekend
By the way the car weighing in at 1400kg flat with 2/3 of a tank ie 40kg fuel and have yet to fit the OZs!
(cats weight 6.5kg each (WITH their pipes - which you can't remove; 4kg each without) - amazing for their size.
And yes, I know that fire ex is way too heavy and gotta go ...
altho its up front and the cats were way in the back )

Are u running stock battery or liter weight- drawback u need to trickle charge it. Pretty jealous that US did not import the 6RS- I woulda gotten one. Simply beautiful ESP red accented 6RS's. Are cupcables in the forceable future : )? Damn I love your car!!!! Mike
