What would be the difference in horse power and performance compared to hooker 2055's if I had a 3 inch y fabricated and pipe of the same back to a 3 inch converter [carsound] and concluding with 3 inch to muffler. Does the headers themselves make a dramatic change or just bigger y pipe I found a shop who will give y and back to converter for 150.00 . Olso I would have hi-flow muffler.

 

The down-pipes for the 2055 y-pipe are 2-1/2". When they come together, it is 3". There wouldn't be any advantage whatsoever to making the downpipes 3" (because that's bigger than the collectors).

The y-pipe is the star of the Hooker 2055 show. You don't need to change anything about it. But, the combination of the headers and y-pipe make it the great system that it is.

Of course, the change they will make depends upon the system you now have, of which you said nothing.

 

Thank you five7kid. I have a 1984 lg4.

 

I GUESS I'M A LITTLE LOST ON TERMINOLOGY AND SUCH. SO A 3INCH Y WOULD NOT HELP MY LG4 SYSTEM ALONG WITH EVERYTHING ELSE I MENTIONED EARLIER.

 

buy the headers with the 3 in y-pipe and get an entire 3 in exaust system. Thats what you wnat to do. Dont mess witht eh stock manifolds, cat, and cat back exaust, it aint worth it. Theyre incredibly restrictive

 

Anyone got a pic of that 2055 y-pipe
