I'm aiming for more power, the same if not better fuel economy, and that low v8-like rumble. I plan to install a cold air intake, high-flow cat and muffler, 2-1/2" exhaust pipes, mod the MAF, and have it tuned for the new flow once all done. May upgrade the camshaft later down the road.
Would it be worth it to put headers on when I redo the exhaust? Or are they just a PITA that's best avoided unless you plan to be turbo/supercharged and pushing +350hp? ]]> BlazerGG https://blazerforum.com/forum/headers-intake-exhaust-10/headers-yay-nay-107722/
