I'm Awesome
After lifting my truck I need to change the crossover pipe to clear the driveline. And... well the rest of the exhaust is a rusty, leaky, sloppily clamped mess that I put together when I was a teenager. Since I'm going to be getting the welder out anyway, I might as well make any other exhaust mods all at once before sending off for a tune.
The truck is a 98 K1500 with a stock 5.7 Vortec. I have 37s and 4.88s and spend most of my time cruising between 2000 and 2500 rpms so that's where I want the engine to run best. I like a choppy, thumpy, old muscle car exhaust sound more than a smooth drone if it matters.
1) Do X/H pipes matter if I have a 2-1 muffler? Or would a y pipe and single in/out muffler be better?
2) Are shorty/mid headers worth it?
3) People say that the headpipe between the manifold and cat is the biggest choke point on these trucks. Could I go to a (slightly) bigger one and keep the stock cats? I live in CA and don't want to mess with smog stuff too much since my truck has passed every smog check free and clear so far.
4) Are stock sized pipes (with the 2-1 muffler) ok for a stock engine? Most headers I've seen have a 2.5" exit, will that cause problems with the stock 2.25" pipes?
