Re: Exhaust suggestions
FWIW, I'll say that not all headers are created equal. There's inexpensive, then there's cheap, then there's high quality. Quality headers bring quality results, but expensive doesn't always mean quality. Some companies just have their cheap headers ceramic coated and slap on a big price tag. In other words, you get what you pay for. Thick flanges with good tube welds on both sides and machined head contact surfaces are a must, then I've discovered to use a light coat of copper infused orange RTV in conjunction with MLS gaskets or no gaskets at all, just the RTV. As for the collectors, stop fooling with 3-bolt flanges and gaskets and get V-band clamps for the ultimate gasketless seal.
However, if overall horsepower isn't the goal, then a nice set of stock manifolds will be fine. Look for a good used set or a NOS set, then have them gray or black ceramic coated by a reputable company and never worry with them again for many years.
