Cat-Backs are either by special pricing or group buy ONLY. 3100 and Quad DownPipes/Porting are available for single person orders at the prices below.
CAT-BACK (metal tank ONLY)
This will be a GROUP BUY if there is enough interest.
The rear section will be from the cat flange area back to the bumper and you can cut out a section for a rear or center muffler if you want. Depending on the tip the muffler will in all likelyhood need to be offset inlet, center outlet. You can see where it goes in comparison to the shield on my car. It's pretty far to the passenger side. This is 304 SS. There are no mounts and this tubing will NOT flare easily so a band clamp will be required to hook the two rear sections together. I buy mine at NAPA, they are not over $10 a piece. As far as sagging goes, it will rub on the rear axle on a car with Eibachs and 400 or more pounds in the back seat when going over bumps unless you put a center hanger on like I have which Cliff and Weba have since copied. You will need to supply the mounts, you can see what I did.
PRICE: $195+shipping

3100 Rear manifold DP(works on 3100/3400/3500 with 3100 rear DP)
This uses a stock flange which you can send to me or I can get for you. Does not require a flex joint for this reason. It will be two pieces mig welded together with SS wire in order to cut costs and allow a better fit. This is put together in a fixture. This is made from SS pipe.
PRICE: $80+shipping if you send me the flange, $140+shipping if you dont(its an hour to the JY people).
This price could go down but on top of me doing some of it I have to pay a professional welder to silicon bronze the cast iron flange to the pipe.
***The DP stock is 1.625" and can be drilled to 2". This will flow better in this area than the stock manifold will flow, even with heavy porting and provides a 51.8% increase in flow area. 1.75" is what I can make it by knocking out the stock pipes (16.2% increase in flow area) for free but 2" requires about a half hour of time with the mill and requires the bit to be resharpened after each cut because of it being cast iron. Add $15 for the 2" hole. This can be accomplished with some effort and a die grinder with a carbide bit if you want to save some money

Quad DP
This uses a stock flange which you can send to me or I can get for you. Does not require a flex joint for this reason. It will be three pieces mig welded together with SS wire in order to cut costs and allow a better fit. This is put together in a fixture. This combined with the manifold porting resulted in a 12 WHP gain on a quad spraying a 50 shot. This is for HO style manifolds. This is made from SS pipe.
PRICE: $60+shipping if you send me the flange, $130+shipping if you don't and I can find a flange.
This price includes porting the flange to increase the flow area 50%

You tell me what you want and when you will have the money. THIS IS A FAVOR for this community. I dont do this because I want to make money, I do this because there is nothing out for these cars in this area and people should always help one another out.
