agreed… think of it this way your looking at 400-600whp at max… now for example SteelCitySupra has 4.5 in exhaust and is producing well over 1000whp… 3inch and call it a day, maybe I can see 3.5… But clearance with the steering column is a huge issue in 240’s… I know first had with that.

Same goes with the 740’s your going to be well over 80% DC at half the 35’s effeciancy… not safe… I suggest doing some serious research before jumping into something like this.
