FYI Dave's got the $$$ in his account now so we should have some details on the cage. Only problem is the Racer is plowed into a corner in the storage lot with 5 feet of ice in front of it and I'd need to drive my SVX out into 7 inches of ice which will probably be there til the end of March. Lots of welding to do!

And for your second question, no. All though it is great on midly built stuff, up to about 260 or so hp. Our stock system narrows down to 1.6" after the pre cats, and this one is never narrower than 2" od. I have a system that ends with a 3" od on a ported and blown SVX, and it would be to big, without the blower. Too big kills the bottom end.

So If I hear you right, no narrower than 2" is ok for 260 hp or so.
In that case, would my requirement be answered by 2.5" pipes? And if so, if correct, would this also dictate that the headers need to be larger also? Joe

It consists of; TWO pipes of 2" for the headpipes, an expantion event, in the form of a resonator, muffler, or cat, or pre-cat where the stock pre-cat goes, followed by two 2" pipes back to a Magnaflow two into one cat with a 2.5" outlet is what we have on the latest in a very long series of muffler systems. Headers is a much easier answer. 1,5/8" primarys, 30" long, into a 2,1/2" (2,11/4" is ok too) collector about 10" long. And for drag or wide open racing, either a twin 2,1/2" dual or a single 3" with strait through mufflers or resonators. Mandrel bent is best, stainless steel holds more heat to speed up the speed of sound creating better scavenging. Unless you are going to supercharge, or turbocharge, or run big NOX, 2" from the factory headers back, and at least 2.5" after that is big enough, and not too big. This link gives an idea, but it is certainly not the last word. http://www.angelfire.com/my/fan/Exhaust_Pipe_Size.htm

Thanks for the excellent detail.. This is what I need to base decisions on.
I am supercharging with an Eaton M110. That is why I mentioned 300-350 hp. I mean that as flywheel HP, not at the wheels. I want a mild upgrade because I am retaining the auto. I obviously need it to breathe well, so upgrading the exhaust is an important change. However, and this is a biggie for me, I want the car to be as quiet as stock, or quieter. I'm aware most people upgrading the engine may want their car to sound like a Nascar racer or something, to let people know they have hair on their chest or whatever. Not me. I want to hear the stereo. So bigger is good, if bigger is quiet. Joe

Tom and I are working on a modified version of Harry's exhaust system. For the time being, we are keeping it under wraps and, if all goes well, it will allow for an increase in power and exhaust flow, while allowing the car to a lot quieter than the original factory system, under acceleration
It will be a mostly weldless system. There may also be a subtle modification of the stock exhaust tips to give them more of a stealth look. This looks to be the most expensive configuration yet, short of a Stebro system, but all of the parts are top quality. If I decide to go ahead with it, I will have done by Reading. .

I'll be interested in seeing that. Graham in England has a custom set-up on his, dual stainless pipes all the way back. He does not have a cat in the system, and I would have to have my car clean. So clean and quiet and breathing deep is my goal. Joe

You guys are crazy in a good way
I'm thinking just running two, 2" mufflers sticking straight out the rear, where the tips currently reside, no resonators or anything fancy and expensive. What I'm really after is a sporty muffler, 2" diameter, that is quiet in and of itself.

Stealth exhaust system
My stealth exhaust system is arriving at svxfiles and all parts will be there bty this weekend. Installation is scheduled from Sunday through Monday.
As I said, it is modified version of Harry's (newsvx) exhaust system. it should allow for an increase in both power and exhaust flow, while allowing the car to be virtually silent under acceleration (or at least a lot quieter than the original factory system) Except for welding the new modified flanges to the larger pipes that connect directly to the exhaust manifold, it will be a weldless system. Nine special stainless steel connectors will be used to insure a leak-free connection, which will be as good as a welded system. The only other weld is relocating the third O2 sensor (OBDII) from its normal position for easier access. If we have time, there may be a subtle modification of the stock exhaust tips to give them a more stealth appearance. This will be all done by Reading. I will post a teaser pic or two as it is underway. .

Well, that's most of the system. Maybe the rest will come in tomorrow.
Now all we need are the larger head pipes and the flanges. As I said, this photo of Harry's car is the basis for the front part of the system. This is sure going to be pretty system though. If I was true to sv-xcess form I would have had all of the exhaust piping alumi-ceramic coated to match... .

It's actually a GREAT idea! That way roadkill and mechanics will have eye candy.
