LTH NOW AVAILABLE for S650 Mustangs - Another Longtube Headers option!

[Logan@Lethal]

This one is BIG!
We're happy to announce another option for longtubes on the S650 has hit the market.

LTH is now available in three sizes (1 3/4, 1 7/8 [our preferred for most customers], and 2") and three midpipe options (off-road/track, catted, EcoF cat [high hp/boosted])!

LTH is historically known for providing quality (304ss) headers with NO fitment issues. They ffit oem connects, so countless catbacks, and require no other additional parts for install.


Longtubes are known to give 20ish rwhp on these cars on otherwise stock form. We're excited to see what kind of power you all make with them.​

If I don’t want to throw a CEL, what is the best route to go?

You'll want to go with the EcoF - the green cats are the only ones that are rated to pass emissions.

We have the S650 option here:

Hey there! The cell count is different so one can withstand 750whp+ vs <750whp

Primary difference! Thanks!
