My question is this I have been thinking about putting headers and a x-pipe o/r pipe on my 2004 mach one Automatic I have talk to Paul the owner at Pauls High Performance who make the intake spacers. I asked does it pay to put headers and the o/r pipe on or just the pipe. How much HP will the headers give me with the pipe vs just the pipe. He told me just run the pipe. For the money and trouble of the install and the car just being a street car it didn't pay. My son has a 2010 Camaro with headers and stock exhaust and we where not to impressed by the headers alone until we put a o/r pipe on which turned the car into a different beast. So I ask what do you guys think headers or just pipe?

 

I think for the cost of the headers and install will disappoint you with the small hp gain. I do suggest the mid pipe and catback upgrade.

 

long tube may net u 8-12rwhp

 

There are basically 3 types of headers, long, short, and custom. Longs should give you around 15 more hp alone. shorts will give you nothing. Dunno what your son put on his camaro, but i'd guess they were shorts.

 

I was hard headed and installed shortys about 3 yrs ago. Still kicking myself in my azzzz....

 

Go for the long tube, and i say shop around for installs, right now ive found a couple places that will do it for $400, and if you look hard enough on craiglist you can find some headers cheap for $100 or so, just make offers, you never know.
