confusion torsion bars or no torsion bars

and talking with a friend of mine and he tells me i need to buy a elimination kit to get rid of the torsion bars as the long tubr TTI headers wont fit with torsion bars in so with eliminating the torsion bars and running coil overs it will work.

Your “friend” isn’t one you should listen to. He clearly is uninformed.
That is one huge problem with this hobby. There are some well intentioned people that are actually idiots. They repeat things that they heard without having any direct Experience in the situation. This helps no one. There are guys that stubbornly stick to the headers are “worthless” argument. Others argue that bigger torsion bars make your car ride like a dump truck. You have to sift through the information to get to the truth OR try things for yourself to come to your own conclusion.
In short, yes…TTI and Doug’s make headers that do fit and do work but there are some drawbacks. The factory built these cars with zero consideration for people to modify them. The steering linkage behind centerline made header fitment really difficult so the cheaper headers do often need to be dinged and dented to fit and clear.
Most often, when a more expensive header has fitment problems, it is because the car had been in a wreck and things have shifted around a bit. Worn and saggy motor mounts are another issue. Bent steering linkage as well. In short, the room for headers isn’t great and when things have been moved or damaged, it never makes fitment easier.
