i have an 88 s24 sorrento and im looking into doing a threw haul exhaust head work and a cam has anyone done any of these? i was wondering more about the threw haul ive talk to a few people and they say thats the one of the best that your can do. i found a local company willing to make the pieces i need but since its all one off its going to be kinda pricey, and i like to buy a kit that has everything i need and all the measurements i need to do the job. thanks for any input
