944 exhausts
Anyone make a decent larger-diameter exhaust for the 944 n/a cars? There are plenty of 2.5", 3", and now even 4" (!) systems for the 951s, but nothing I've seen for the n/a cars. I realize this might be because the turbo cars benefit more from it, but I am in kind of a weird situation given the Callaway system intended for my n/a car.
I hate the thought of going "custom". It's expensive as hell and impossible to just "replace a pipe" if something rusts / fails / breaks / whatever down the road. You end up paying 3x as much as you would using a quality (but "off the shelf") aftermarket part. TIA

The muffler shop up the road builds "custom" pipes really really cheap. I am sure there is one in your area.
They have lots of different diameter stock
They have a hydrolic bending machine right in the bay
They cut it, bend it, and weld it in
Hour or so later a custom dual truck exhaust including 2 dynaflow mufflers and 4" tips = $225
This tubing isn't made of gold ya know.

With an N/A, you're going to lost power after 2.5". SFR makes a 2.5" system for the N/A - which is what I have. It added quite a bit on the but dyno. The backpressure will not be enough if you go over that size. If you're going to put a turbo on it, then go with a 3" system - but as long as the turbo is off there, you will be losing power.
There was someone that had a 3" on his N/A a while ago and went with a 2.5" when it was replaced.

The factory muffler is already a good muffler for the car. What I did is I cut the catalytic converter off an old down pipe and just had a piece of mild steel welded in. I have a clip of what the exhaust sounds like. It's decently loud and raspy and sounds sweet if anyone would like to host it. For now here are pictures...

The stock cat does have a resinator at one end, so you will hear a difference. I already set off the neighbor's car alarm on the way out of our subdivision, so I'm not about to go making it louder by doing that mod.

Just don't get busted without a cat on there. . . I'd personally keep it and just go with a high-flow model to avoid any unpleasant suprises with $1,500 tickets on some CHP spot-check somewhere! Yes, they're doing those now so I've been told. . .

Any loss of low end without the cat?
My exhaust was recently busted between cat and collector and it drove like Sh#t.
PoP - Do you really want stainless on a pipe no one will ever see? If so, I do understand.

Exactly my point. If I were going to do anything like that (which I wouldn't) I'd retain the "shell" of the cat and wrap it around the test pipe with the seam weld or tack welds facing up, so they couldn't see it. It'd still be a bit tough to pass the sniffer test I imagine though. . .
