1 7/8s or 2" headers?

Which one will be a better header for a C/H/No2 setup? Also how would a 2" act on a bolt on car? Thanks.

What does "C" stand for? Either way, I would say 2" long tubes for the drag strip if that's your thing. There's more upper rpm power there even with just bolt ons

Yeah, the "bolt on" car designation is throwing me a bit

I doubt 2" will give up much, and with n2o or the need for more power later you will be covered. I would just go big. I wish I did 2" the 1st time.

2" gains on the high end. If you're going "full bore", they're good for a few extra HP at the top of the RPM band. 1 7/8" are sufficient.

Sounded like some Breaking Bad Meth stuff for a second.

2" gives you a lot of room to grow.

These cars like the 1 7/8" alot and the 1 3/4" Tri Ys even more. Be happy to help if you have further technical questions. There are a lot of good choices out there!

That would be the best choice for your application.

+1 on the 2" headers for what you need, absolutely. Post up pics when you get 'em!

2'' is a waste IMO. Depends on the application though too.

2'' might get you a few HP up top but might lose needed torque down low.

Testing has shown that the 2" and 1-7/8th headers have similar gains in the lower RPMs. The 2 inch will make more higher in the RPMs. Any losses down low will be minimal if any at all. And with forced induction or more extensive mods, the gap will become wider with the 2 inch. They are definitely not a waste.

I've seen the 2" headers make a little bit more peak hp over a 1 7/8" side by side on a virtually stock car! Just something to kick around!

The Texas Speed 1 7/8" & 2" headers are about to arrive & be back in stock! I am thinking we will see those dudes late this week or early next week!
