Of course - but by straight i meant no bends.

The same theory still applies - do your catback at the right diameter and choose your components carefully based on your preference on sound vs performance (i'd personally go for nicer/deeper/quieter sound on a street driven car.. some would call me crazy).

You also need to be aware that you have the integra luxury model, with the intake-only-vtec, is it worth going for a full exhust later when you know you'll still get cleaned up by a dc5r? but that's up to you to decide.
