i need some pics of how its done every exhaust shop i go to has said it cant be done with out cutting up the floor

 

the only way i can see 3.5inch true duals is dumping them before the axle on a race car with tall rear tires...else you wont have much ground clearance... but you really dont need 3.5inch true duals. thats probly for cars pushing over 1000hp or something

 

100%.. 3.5" duals is not a small exhaust and is not needed until you are in the low 10-high 9 second range.. a 3" dual will take you a LOOOOOOONG way.. dont even argue the topic until you have your car making 700+rwhp..

 

Look under exhaust in tech, I have seen pics of 3" and if you don`t want your exhaust dragging on the ground, I don`t think you can go larger.

 

ok my car is a low 9 sec car it is a 421 with sb2.2 heads so i do need it the motor should push out in the rang of 750hp

 

Did`nt know that. Where do you drive it?

 

mostly the track but i do drive it on the street some times and i dont care if i have to dump it b4 the rear

 

oh wow.. cool.. learn something new everyday.. well since you put it that way, i would just follow the frame rails inward then the edge of the trans tunnel and dump by the u-joint

EDIT: please, do post pics of your motor.. i wanna see that..
