ok iwhen i put my custom H pipe in i didn't weld it in i just used clamps. well over time these wore out and the H pipe come apart. the car got real loud like it was running open headers. so today i have spent the last 2 hours welding the h pipe up so that it is super tight. now the car is quieter. (of coarse) but it seems as if the exhaust is really restrictive now. it seems like the car is much slower than it was with the H pipe open. i have 2 1/4 inch pipe . could this size pipe be restrictive? would it be better for me (performance wise) to run the open H pipe or cut outs? or does it just seem slower cause it is quieter?
