Just drove my 98 Sierra OBS swapped 5.3 for the first time last night. Wanting to know what you guys have done for exhaust. Right now I have Schoenfeld full length headers and thats it, not leaving it that way. Will run high flow cats after the headers, trying to keep it somewhat emissions legal, but what have you guys done from there? Want it to have some rumble but not obnoxious, true duals with same side exit, maybe something like 2nd gen Lightning style?
BTW, I do have a cam swap already planned...
