RE: Best option for new exhaust
Please note that the following is an opinion stated strongly by a young "whipper snapper", I know old people may be offended by opinions on the internet, but fear not, you can scroll past this to avoid such an annoyance.
You guys spend crazy amounts on your car. I havent added it all up yet but with my used blower, new fuel system, complete with an Xcal2 and dyno tune I will be around $2000 +/- $150-200.
The car's not worth $7500 and for 7500 youd better have a 10 second car or you need to stop working on cheap cars and buy a freakin Cobra.
My car is supercharged:
Used Novi 1K
New 42lb injectors
New Walbro 255(selling it on ebay for a SVT Focus Pump and basket which is on its way)
Used Shurflo DIY Methanol Kit (tapped into washer resivour)
SCT Xcal 2
+ other mods unrelated to the supercharging of it.
Youre now making enough horsepower to send your rods/pistons/oil pump gears to the bottom of your oil pan. You also have an extremly unique quick car. The only other things you really need to be VERy close to an 11 second car is a converter, DRs, trans cooler, and gears.
No 16-18 year old should ahve an 11 second car. Usually a 12 second car is to much for someone our age. I say our because I am 17. If you nail it some time which you will do, the tires are spinning, rear end starts to slip, you correct, then they finally bite and you get launched sideways into someone. It happens at the drag strip, on the street, to all kinds of people. Especially people inexperienced like us.
Lastly, get a centrifugal blower. Theyre are simpler to install cheaper, more readily available, fit under the stock hood, etc. etc.
