ok what header would you say would be the best for my duster? the computer tells me that my combo is worth about 525 to 550 hp. please and thank you for your concern!
You need to ask yourself some questions, and make up a decition for yourself. I just thought your reasons where un valid befor. ask yourself these questions.
What am I wanting this car for? street? street/strip? or Strip only
are you going to compete competativly, or just for fun.
How much money do you have for headers
are you really willing to cut your inner fenders out, knowing that it will cost alot to Re-patch them if you wish to at a later date.
Do you want a engine with ease to work on?
Do you want Clearance issues when driving?
do you want clearance issues with stearing?
do you want heat issues?
do you want to have full exhaust or not?
do you want a stock look or a race look
are you going to put in frame conectors?
are you going to brace the shock towers?
People have heard me say this befor, and its a personal preference. I just don't like the look of fenderwells. If I was making an all out race car, then yes, I would use them, but otherwise I would use underchassi, or exhaust manifolds.
