ok so i got intake, and catback exhaust on my 03' P5. i now am gettin money together to do some more performance stuff. i was thinking either cams or header and DP?? what would be the BEST HP for the $$?? i need some ideas, im confused on what to do...

I'm assuming you have a turbo car?? you need a downpipe??

I would recommend a nice header and an MIL eliminator. Cams are not available yet. You should check out my cam thread in the vendor section for info.

pr5guy

nah i dont have a turbo car. Wagner has a Dp and a Mp for sale i meant the midpipe.. the high flow midpipe wagner has, does it connect straight to the header? and what is an MIL eliminator?

Roddimus Prime

if you're using the wagner header with your stock DP you will not need a MIL fix. If you add just the midpipe you will NOT need the MIL fix. If you use the header with a cat-less DP and cat-less MP you WILL need the fix.

pr5guy

yea i cant go catless thanks to emissions friendly NY... so the DP would take out a cat? so what if i add the header, DP and hi flow cat? will i need the fix with that?

Roddimus Prime

If you have to pass a sniffer test (only) I would suggest buying the wagner shorty header and the midpipe WITHOUT cat. The second cat doesn't really do anything anyways. The header will provide a good gain and the midpipe coupled to a nice cat-back will give you a big top-end push. Should make for an overall nice ride.

ok so doing the header, midpipe and along with my catback exhaust i already ahve will give me a full complete exhaust?

macdaddyslomo

yes but really you need a free flow cat to eliminate all restrictions

Roddimus Prime

yeah I would just buy a bolt-on exhaust that eliminates the cats and when it comes time for your testing you just swap the stocker back on.

pr5guy

that would be cool but it would just become a pain in the neck. metal under heat too explands and contracts when cold so the pipes might not lineup right anymore

pr5guy

any word on cams yet??

It really wouldn't be too awful. I've taken apart the entire exhaust in about 3 hours. So 6 hours total every 2 years for emissions isn't bad at all. If you do get the shorty header and midpipe/downpipe instead of a full length header, your time will be much less I'm sure.

Roddimus Prime

yeah, don't be lazy. Performance is all that matters!!

pr5guy

ok so shorty header, hi flow dp and hi flow midpipe is the way to go then?

Roddimus Prime

yup, then your choice of cat-back....you'll have awesome system...probably net you 20hp!
