Ok I have 2000 rcsb silverado 5.3 2wd and I have it at a 4/6 drop, would long tube texas speed headers work? Or will they scrape? If they scrape what's my next best header option? I wanna do true dual slp loudmouths with a x pipe, but not sure if I should use 2.5 inch pipe or 3 inch pipe, and what to do about where to make my cuts to make true duals, any info is much appreciated thanks!! Here's a pic to show how my truck sits

 

Not sure about the clearance, I would run 2.5 piping, get cut outs installed right before x pipe if there is room.

 

My truck has 2.5 duals, I did 3" duals on my buddys truck and its too much exhaust, bottom end power took a hit.

 

Ok sweet I will stick with 2.5 then

 

Any reason why you want to run duals? A single 3" to a single in dual out would still sound great and give you the performance you want. Are you going to run cats?

 

I agree with Andy. Depending on how far you want to takek this thing a mandrel bent single 3" is your best bet. As long as you stick with the 5.3 NA you will never out grow it.

 

I just thought it would be better flow doing true duals but if I can get the same performance out of a 3 inch single Ill do that, and that brings me to a new question if I do 3 inch single will I have to get a off road y pipe to be able to run 3 inch tube? And I'm gunna most Lilly use a slp loudmouth and dump it

 

Yes I have to run cats where I live

 

That thing sits amazing. Beautiful!

 

Thank you lol it's pretty much shaping up into my dream truck, it's a forever truck for sure
