Need Help, Exhaust Size for QTP
Need Help, Exhaust Size for QTP Hey everyone, I'm a former import driver gone domestic, and alot of this new lingo is confusing.
My 02 Z28 M6 has borla catback, and I want to purchase QTP headers. Thinking I was getting somewhere by finally selecting the brand, I see they offer 2 sizes, 1 3/4" and 1 7/8". What the heck?
and what the heck is a high velocity collector? omg..
1 3/4" 2001-2002 with Air Fittings $799.99
1 3/4 1998-2002 High Velocity Collector $1249.99
1 7/8 1998-2002 High Velocity Collector $1349.99

get the 1 3/4 with air fittings. 1 3/4 is the primary size.not worth the extra hundred for the high velocity collector. only going to gain you a few hp. 1 7/8s is for a car that is going to be making huge power so unless your planning on huge power the 1 3/4 should be fine.
on oldschool sb chevys the norm was 1 5/8" primaries with 1 3/4" if you are making good power.
the newer motors lt1/ls1 flow much better than the old ones and it seems the norm is now 1 3/4 on these with 1 7/8 being for highpower/strokers.
the h/v merge collector option is 400 bucks. Unless you have money to blow go with the normal collector. the QTP y pipe is one of the best on the market as well.
~1300 for the standard collector with Y pipe
~1800 for the merge collector and Y pipe

if you arent going to go with a big stroker motor just get the regular 1 3/4 headers.... QTP are IMO the best headers out there... i had another set from some other company and they rusted out..
i run the High velocity merge collector headers.. its for squeezing a few more horses out
