I currently have a 2000 5.3L (Comp Cammed/ Pacesetter shorties/ K&N CAI). It currently isn't tuned properly because i am waiting for a 3000 stall to come in. My questions are with my exhaust. Currently I have 3" straight pipe ran to a single 3"in/out Black Widow Pro Venom 250 muffler. The cats were cut out. My truck is sluggish from a dead stop. Am I'm I losing power by this setup? What setups do you guys recommend?

Im contemplating going back to a race flow cat set up with a cat back setup. Is there anyone out there that has the same engine work (or close too it) that has a good exhaust setup and if so what do you have?

Im new to the forum thing, so any advice will be greatly appreciated.

Thanks

 

Get a proper tune before you consider it sluggish. What size cam? What do you expect if it isn't tuned?

 

Comp Cams ***** Thumper .522/.509 (part# K12-601-8). I will have it tuned as soon as my Yank gets here. But after speaking with a local tuner, he suggested that i reconfigure my exhaust. So i was looking for ideas on what people are running out there. Just wondering if its a pro or con to have cut the cats out and ran 3" pipe from the headers back to a single muffler.
