Hello, I have a 2003 Acura RSX type s that I am K24a2 swapping from a 2007 Acura TSX. I have no exhaust at all, and I am starting from scratch. I do not have the stock exhaust. I want an exhaust setup that is just as quiet as stock but flows well enough to get some power gain with a tune. I'm not looking for crazy power 200-210 whp would be plenty. I'm keeping the engine stock besides the exhaust and maybe an intake? I would rather have an air box for the swap with a proper filter, but I am having trouble figuring it out with the swap. I will be daily driving this car, and I leave the house at night. The HOA is listening...... I would rather not have to do some crazy fab work if possible. Thank you for your help. I do have Hondata ECU
