downpipe

i'm running a 3.5 pulley with colder NGKs, FWI, and a 180* tstat. i'm looking through ZZP for a downpipe, but i'm given a ton of sizes and special trims. off-road, shorty, with a cat, etc.

i don't really want to go with welding, but i really don't know what the differences are between these. i hear you should go with a 3", so that's where i'm trying to troubleshoot.

any ideas on which would be the most efficent? i appreciate the input! :th_thumbsup-wink:
 


If you don't have to worry about emissions.. get an off-road (no cat) downpipe... it just bolts in. You don't need a shorty.

Headers are more expensive... but they gains are alot better.
 
excellent! thank you for the quick response! michigan is in crappy shape economically, but i sure do love not having to deal with the tests. :D

i was going to start with the ceramic coated manifolds and upgrade when i have a better budget. things are stiff at the moment unfortunately.

but i'm definitely looking forward to a good pair of pacesetters!
 
The rear o2 sensor just shows whether or not the Cat is "working." It can be deleted but will set a code and SES light. This can easily be removed via a tuner or o2 emulator. The rear o2 serves hardly any purpose and mine is deleted and tuned out.

speed daddys arent that much more than ZZP's DP's... 220 shipped to ur door for headers... i forget what ZZP's prices are.

it can be set to non report for no ses light.. deleting it isnt a good idea. i forget the years.... but i think its 2000 thru 2003 u CAN NOT delete code.. it will cause u to stupid rich also there are no GOOD set of pacesetters out there.
 
Its hit and miss with the 01+ cars for the 02 sensor. My car is fine with the code deleted and others are not. I would get some headers.

I beg to differ. Mine are coated, don't leak at all...and are 2 piece just like ZZP's. Only difference is slip fit vs. my 2 bolts (front header to crossover). If you don't want to take the time to have them welded up then they aren't a good buy and they used to be awesome budget headers...but time moved on and now SD headers are where its at. Get them.

mine are coated too... and i followed the welding instructions by bluegtp
 


yesss that way i can use the money instead for a local tuner. it's funny, i haven't fired this car up since the head gasket blew seven months ago. i've been taking succhhh a long time doing the whole thing, but i've been ordering and installing mods along the way. it was bone stock before with shoddy vacuum. i'm so excited to see (and hear) it fire up now. :D
 
if u do get the speed daddy headers.... dont be shy with copper RTV on joints.. let it dry for the 24 hours they recommend...
