I was just wondering if Pacesetter long tube headers part# 70-2253 (1998-1999 LS1 F-body with Emissions Fittings) are a good choice for my 1998 WS6?
I want your opinions on the Pacesetter's compared to other brands like Hooker or SLP?

I do not know how exhaust systems bolt on but would I still use my SLP y-pipe and just have the headers connect to them?

I do plan on getting an aftermarket catback system I was going to go with mufflex since thy are about an hour away and they seem to know what they are doing. I figured on the 4" catback with flowmaster or spinteck muffler that is what they offer no idea which one and I hope I can keep my 1OTL (1 On The Left) pipe instead of dual pipes.
