I dont notice much in the cabin noise, if anything the acura is slightly better. The ELS system is the best car stereo ive ever had. The Bose was better than a typical honda factory system but not by much.
the SI is a tad bit faster and just a little better handleing. If i could have found...
Ive owned both. I drove SI for 8k and my interga for about 1500. the SI suspension is slight more aggresive than the integra in sport mode. I hit deer in my SI and couldnt find another one so i bought an integra.
