Dual Exhaust no h or x
Was wondering if it would increase performance if i put on dual exhaust, with cats but no mufflers and just ran strait pipes back from the cats. with no X pipe or H pipe, i ahve heard that this can cause minor backpressure problems but its nothing that will damage my car or degrade performance. just want to confirm this or make sure im not going to do something bad to my car by not having an x or an h. but from what i see. if my car has a y pipe anyways right now. the backpressure can only be better with 2 seperate pipes.
