    Default Upgrade from 2.5" to 3"?

    Hey!

    At the moment I have a 2.5" custom exhaust on my EP3 and I'm wondering if it is worth upgrading to a 3" ktuned oval exhaust (used one not new) if I'm looking for the most power as possible?
    If I upgrade about how much hp would I gain?

    The setup I will be running: RBC inlet manifold, dc sports exhaust manifold, Injen cai & Kpro V4 and possibly E85 conversion.

    Thanks in advance!

    I'd recommend a 3" solid fabrications system on mine, with same inlet, same exhaust manifold as you and it made 270.1bhp.

    Try and stay away from the "scene" Jap brands as you're more often paying for the name.

    I've heard of Solid Fabrications before and I checked on their site and the cheapest exhaust for EP3 is £530, don't feel like spending that much unfortunately. I've seen ktuned 3" system for £300-£350 used which I think is a fair price.

    If I find a used Solid Fabrications system then it will definitely be an alternative

    I would forget about it when talking about K20. K24 is totally different story and 3" boosts the mid-range.

    5hp for £300-£350 doesn't feel worth to buy to be honest. Hmm, I'll have to see. Thanks for answer!

    Will there be noticeable gain if I upgrade to a Skunk2 megapower r which is 2.75 inch? Seems to be kinda hard to finding a used 3 inch...

    Much better things to spend that money on. What other mods does your car have?
