Thinking about a DP or IC?
Do you have these items already in place?
Unshrouded compressor housing --> HP cat converter --> dual UltraFlows?
Progressive methanol injection and a boost controller?
Attention or concern to any logical progression of mods would
indicate the above being completed before considering a DP or IC.

Unshrouded compressor housing? I had a TE-44 which disintegrated so now I have a T3-T4 for the time being. I have SMC alky. No need for progressive since it does just fine. I have a boost controller. The IC is just a dutt neck. The car already had the turbo and pocket ported heads when I bought it. It was a disaster in terms of modding. Full stock exhaust from the 80's, all rusted to hell with some tiny no name cat welded on. Whoever it was, sawed the 4 bolt flange off and welded the DP to the cat, and welded the cat to the catback. So I couldnt just go buy a cat or test pipe or anything since everything was welded together. I could buy a 4 bolt flange, but getting the positioning of the flange would be difficult. It would have to be in the proper location if I were to try and install a catback. It would be better to just get a new DP to get the flange back. Top that off with a 7.5" rear end with 4.56's and a 4200 stall non lock TC, stock cam, stock intake, leaking stock injectors with cracked o-rings and massive vacuum leaks everywhere (the car barely ran), cheap autozone plug wires that ohm'd all over the place, bad ignition module, bad cam sensor, bad sensors all around, cracked spark plugs, stock intake tubing with holes in it, cracked headers and a million other problems....you can tell the guy was a dimwit. Ive done alot to try and get things better matched. I spent alot and did ALOT just to try and get the car to a decent base condition to start modding. But then the paint started cracking open everywhere (Im driving around with no paint on the passenger side since I stripped it), the steering shaft is GONE, no horn, no high beams, stock steering wheel and hub are gone..some autozone steering wheel sits in its place...discovered the whole suspension consists of original shocks all blown out and the whole suspension is rotted to the point its metal on metal in some places...I could go on and on. Everytime I get one step ahead, 5 other things go bad....I sort of bought the car without driving it and really looking closely, but I had just sold my cobra the day before and had no car and my wife was being a PITA, saying she wasnt going to drive me to work...I was going to do the exhaust next but ran out of money, and from all the posts I had seen, the exhaust mods didnt really seem to do a whole lot. A catback may do more. I havent seen too many ET gains posted pre/post catback. With the TE-44, I could give it half throttle in 2nd gear and I'd be all over the road. It already had more power than I could get to the ground, so something to increase spooling speed didnt really appeal too much, since it already spooled like crazy. I can get a custom mandrel bent 3" single system made with a 3" carsound cat and magnaflow muffler for $500, but Im wondering if the DP will be worth my time and money. At the prices they run, I have a hard time justifying almost 500 bucks for 2 tenths.
