Anyone familiar with Honda Si's? Is it a wise move to add some bolt on's to a stock Civic Si?

    Bought this thing new in 2007 and it has been kept stock.
    Currently has 135K on it, and I've been thinking of adding a header and catback (non-farty) to put a little bit of new feel back into the car.
    Never had any mechanical issues, and the car still run and drives just as good as it always has.
    Am I going to mess up?

    You will add some pep in the upper RPM range, but being a 4 cylinder and naturally aspirated you are looking at about 10-15hp gain at the wheels maximum from basic bolt ons. If you have emissions where you live it will be less. As far as the "farty" noise, some exhausts are less loud, but they all add that type of sound. As far as reliability goes, you have nothing to worry about. Hondas will run forever if treated right.

    Intake, header, and a catback are all simple bolt-on mods that may free up a few ponies, may not notice any difference on the "butt dyno" but hey, louder = faster!

    Along with intake, header, and exhaust...add a high flow cat and flash the ECU and you should feel noticeable power gains. Just don’t go cheap. It’s got 11 years and 135k on it so I don’t think you will be hurting the value of the vehicle froma resale perspective...just keep the OEM equipment and don’t remove the cats or do anything that would prevent it from passing an emissions inspection.
