got an exhaust question
 

Ok I was looking at buying a HKS dragger exhaust for my N/A 87 supra but HKS says it wont fit I didnt think that was anything different between the way the exhaust mounts up to the cat or is it you will get decreased performance from such a big exhaust. I plan on buying a 1JZGTTE for the car, actually it is being shipped right now so the exhaust would complement it well. I was also wondering if I need to buy a front clip or will a complete motor be enough with the engine mount adapters.

I was also wondering if all the mod parts for a 2JZGTTE will fit on a 1JZGTTE they look almost exactly the same from all the pics I have seen of them side by side. I am looking for like twin turbo mods and intercoolers and things of that nature so any help would be very appreciated:) .
