Curious as to why you wouldn't go under chassis? guess I thought the front exit was more of a product of having to with turbo set ups due to room. We have a phenomenal header shop out here in Kingman AZ (REF). Call him up, make an appointment, drop the car off in the am..... by 2-4 that day you'll get a call back that your pipes are done and come get your car. I'm very fortunate to only be an hour away from him.
