custom exhaust Options

[Tsizzles98]

This weekend I am getting a full 2.5" exhaust from my header to my muffler, my car is already pretty loud but I was wondering if this will make my car obnoxiously loud and it may sound to ricerish. I do not have a cat, or a resonator. So can anybody tell me what the results may be?

Going catless and no resonator is dumb. Why would you do that? Is it because you think you'll get mad crazy tyte jdm horsepower by running without them? Or are you just cheap?


Look, an intake, eBay header, and exhaust will net you very little gains. We're talking 5hp max, but realistically 2-3. Don't be dumb, don't be cheap. Buy a high flow cat and a Vibrant ultra quiet resonator (or whatever brand of similar design). You will have a subtle tone that won't attract the wrong attention, and keep you emissions passable. Running without a cat will make your car stink, and without a resonator its going to sound like a crappy Honda - even more so if you have a fart cannon muffler.
