i know some of u guys running this on ur suby.

which one would buy first?

 

Even if we are running them...we can't tell you reliable numbers because we have no dyno here.

Check the review section.

 

^^^ dont they have a dyno at endless garage?

 

Well if they do...they should really be announcing this information to us. I know that many HIICers have been wanting one.

Anyways they probably have a 2 wheel dyno and say that they can turn AWD cars into 2wd just for the dyno runs.

 

uppipe... is an uppipe and the only ones that I'd pick out of the ones you've listed is the APS one since it's a 2 piece design utilitzing a flex piece for engine flex.

I would also recommend going with PDE since they have a flex type and non flex type.

Downpipe and header... can only be told with a AWD dyno which NO ONE on the island has!

it's header and not HEADERS... you don't need one as of right now

 

catless downpipe.



i have one not in your list.. a divorced wastegate DP that throws cel's...

 

Some say the flex section will disrupt the exhaust flow... well, it's your call. Keep in mind that JDM spec is shorter than USDM downpipe. With the Cusco, you will need an JDM Spec Catback system like Fujitsubo, or Kakimoto...

I really like my Crucial Racing up-pipe. It's made out of 321 Steel (not 304) and it's ceramic coated to keep the heat in. My only complain is one stud was a lil bit too long...

 

hehe you said tuds

 

Hehe... I know... I said tuds.

 

Can't believe you're still pro crucial... I'd be pissed off about the stud thing, considering both the UP and DP are from them!

 

It's only minor thing, it really is because the stud was only 1mm longer... I dunno... I'm a sucker to 321 steel...

 

well there are some great brands as far as up and dp, which aren't on your list. if you want best hp, off-road piping is probably the best. do more research...and then decide...sometimes you pay for the name brand, when others are just as good or better

 

yea they do....but not an awd dyno. check out the reviews section and gl.
