Car: 1991 Mustang LX

Part: BBK Long tube headers and Offroad H-pipe
Pro's: Great headers, made the car sound like a beast and the power increase was substantial.
Con's: It was a little time consuming to install those headers but worth it in the end.

Part: Autogage 5" tach w/shift light
Pro's: Great tach for a great price, install was a sinch.
Con's: None.

Part: Mega-Bite Jr. lower control arms
Pro's: Best control arm on the market, dual settings are available with it. Makes the car launch like a rocket.
Con's: Kinda hard to install, requires a 100ft-lbs minimum impact socket gun (to loosen the stock bolts) which I did not have :) You'll need multiple jackstands and a really big hammer for these puppies.

Part: Granatelli Double adjustable upper control arms
Pro's: Made the rearend MUCH more responsive, then again they were installed with the mega-bites. The combination is outstanding though.
Con's: None, install was rather easy.

Part: Kirban Adjustable fuel pressure regulator and gauge
Pro's: Fine tuning of the fuel pressure made easy.
Con's: None.

Part: Adjustable Pinion snubber
Pro's: Very easy to install, takes 5 minutes and helps control the pinion angle.
Con's: When mine is in race position it makes the ride a little bumpy.

Part: GT40E Intake Manifold
Pro's: Great manifold, a lot of power can be freed up with one of these. This manifold in particular can flow boost very well too.
Con's: Since mine came off of an explorer, some of the EGR and sensor bungholes are not there. I don't care about EGR or the sensors but some people do, this can be problematic.

Part: C&L 73mm MAF
Pro's: Freed up lots of power, install was a breeze.
Con's: C&L MAF's tend to be tempermental and don't like air turbulence.

Part: BBK 70mm Throttle Body and EGR spacer
Pro's: Freed up some more power.
Con's: None.

Part: Lakewood 50/50 Drag shocks
Pro's: Helps with launching and weight transfer, very noticeable.
Con's: Shocks still seem a little to stiff, maybe it's just me.

Part: PTP 3.73:1 Rear Gears and Richmond master rearend rebuild kit
Pro's: GEARS RULE!
Con's: I didn't install them so I wouldn't know.

Part: Summit brand harmonic balancer
Pro's: Cheap and easy to install with the puller. Reduces vibrations by a whole lot.
Con's: Starting to rust so I'm thinking of painting it. Can't re-use stock bolts if you have underdrive pulleys. You'll need to search for the right length bolts.

Part: Prothane engine mounts
Pro's: Great mounts, makes the torque transfer to the wheels much more responsive and reduces vibrations.
Con's: Loosening the motor mount bolts was hard without the impact wrench.

Part: Energy Suspension Transmission mount
Pro's: Reduces vibration.
Con's: To install requires some filing of the tranny crossmember.

Part: MSD 6AL Ignition box
Pro's: Helps gas mileage and idle.
Con's: You don't feel this mod in the seat of your pants, it's one of those mods that does help all around though.

Part: Autospecialties Underdrive pulley set
Pro's: Easy to install and instant power gains.
Con's: You might have a problem charging your battery if you have a big sound system with a stock alternator.
