once i hit 4000rpm my air/fuel dropped down past 12.5 and eventually hit the 10s. so there should be some hidden power there.

im just waiting for HPtuners to come out with their new USB cable, then ill order it and get to tuning.

Red line is stock with HPPIII and 160*
Blue line is with whisper lid, HPPIII, 160*, LTs, TDs

Badass post man. Just fyi, you can get a serial to usb adapter, so don't let the lack of a usb cable steer you away from it for now.

 

Btw, do you have pics of how you got the pipes out the back?

 

i know about the adators, i just wanted one piece. also it gives me an excuse for now shellling out the $500 bucks for it

edit - yes ill add them in a sec

 

k added teh pic

 

that sounds great man it really does. which mufflers are you using? those are
some nice gains as well, you can definately feel that kind sotp. if your a/f was
that far off, i'd be willing to say you'd probably gain somewhere from 5-10 with
a tune. its a totally different animal now that you have a full exhaust isnt' it?

 

what lowering sprngs r u running? wondering about the clearance

 

Looks and sounds great man! Awesome post!

Think you could grab a few more pictures of whats going on from the mufflers back? I'm having the same done on tuesday to my duals with the exception of having 3 bolt flanges at the mufflers. Maby a shot from directly behind the car? I would really appreciate it!

 

when i get home tonight ill post more pics

 

yeah wha springs you got, i'm lowered and hitting speedbumps with the stock **** on, how your clearnace by the way?

 

oh yeah question, cant really make it out, when your doing the driving, is the pipings goin all the way to the back?

 

very nice sound

 

the rear has the rubber hose mod for the springs.

yes the piping is all teh way to the back. that last pic you can see i have tips

i fixed the dyno vid link

 

that last pic pretty much shows it. just comes out and goes under the axle.

 

love the sound. Great work!

 

Ive never had an X system go lean...Then again the junction couldbe the culprit and causing a back up of exhaust flow. If anything a car should run leaner and want more fuel to be added via a tune.

 

well if you look my stock A/F is almost the same. its a little leaner. i think it may be the HPIII

 

Regardless of the HP3...it should go lean...then again you have a 160 thermostat and it keeps the coolant way to cool to make optimum power up top and efficiently burn the fuel in the chambers...

Im telling you from many a experience...well built duals will make a car go lean. All the extra exhaust flowing out, allowing the car to ingest more air. The only thing missing is more fuel because thats all a predetermined amount based on stock tables.

 

well my graph is super rich, so i gotta lean it out

 

Sounds good..
Did you install the long tube headers at the same time?
