Are these any good? Looking at the PSM-70-3221 long tube headers. Just wondering if anyone can tell me if the PaceSetter Long Tubes will work okay with the Magnaflow Catback I already put on. Also will I need anything else to install these in line with the Magnaflow..

Also are the 03 Mustangs equipped with EGR?

 

From personal experiance here, do not put long tubes on a stock V6 with Magnaflows, really, really, really sounds bad, it sounds much better once the car is moded, but stock the car just doesn't push enough air to get the true tone out of the mags, in short, you'll sound like a rice burner.

 

Well what mods are you suggesting prior to doing the headers?

 

All of our cars have an EGR. I'd get the MAC headers because then you don't have to worry about deleting the EGR or modifying the Pacesetters to work with it. If you delete the EGR, you'll need a tune, which will cost more $$. Get some sort of chambered muffler (Flowmaster) and it'll sound good.

As for moar powah... he's talking cam, heads, supercharger or turbo... expensive stuff.

 

Pacesetter makes a good product but if they are net set up for an EGR system you will have to have the passenger side header modified with a threaded EGR bung and a custom EGR tube.

 

i <3 my MAC headers
