sup everyone am in needing some opinion on this am buying some
QTP LT 1 7/8s headers but not sure if it will be to much for my ls1 with a mid cam ,ported heads,with 3" y pipe K&N cold air intake,deleted egr and tune

 

No, 1 7/8 headers won't be too much for your setup. It will compliment it very nicely.

 

No not big at all. Once a cam goes in its a must IMO

 

I was planning on doing TSP 1 7/8 headers with ORY on mine long before I do a cam swap. When I did my first cam when I had my Formula, I probably lost power due to being choked on stock manifolds and cats. I put the Mac mid-lengths with ORY and it opened it up big time.

 

oh ok thanks for the help i also will be on a nitrous plate 100-150 shoot

 

1 7/8 should be just fine it would compliment the other mods
