Full exhaust installed!!!

Well, technically not yet, but it is getting installed as I speak. I am getting warpspeed aluminum mandrel bent y-pipe, warpspeed metallic substrate cat, and apexi world sport cat-back put on. My current mods are Place Racing CAI w/apexi power intake filter, and unorthodox underdrive pulley.

My previous dyno and times were done on my g-tech pro competition.
1/4 - 15.3 @91.3
0-60 - 7.1
HP - 165 @5400rpm
TQ - 180 @4400rpm

I am hoping for an extra 25 HP to the wheels and break into the 14's
I will post my results when i get back from the shop and hopefully someone can host some videos and sound files for me.

Honestly man you will be lucky to get 5-10 HP depending on how much you have already done to your car.

disregard my last post. With that setup you should see 20-30 HP. I did not read the part about the Y pipe.

Auto or 5spd? I think 25hp to the wheels is really stretching it. More realistic gains would be 18hp or so. Most guys with those mods dyno around 180ish to the wheels

Well im back. My car sounds awesome. Definitely not too loud, no farting noises, no bees in a can, but definite rumble! Kind of sounds like my brothers GTP exhaust note. They had to take off the tow hook, and the o2 sensor in the b-pipe didnt come out. Will be replacing all 3 o2 sensors and knock sensor next weekend. I did check codes and got 0209-o2 sensor, and 0304-knock sensor which only came on because of the o2 sensor. I also reset my ecu.

I will do some gtech tests later on tonight to compare. I feel a huge difference all across the rpm band , but mostly in 3rd and 4th from 3000-redline.

By the way I have a 5 spd. I now have CAI, UDP, Hi flow Cat, MB y-pipe, apexi cat back,ngk plugs.

My next mods will be AGX/progress combo with fstb and addco rear sway bar in December and then the Geforce ECU upgrade in January.

I only did one test on my gtech about a half an hour ago. Ill do more tests tonight including 1/4 times.

Previous best HP/TQ on gtech

165HP@5400rpm -gtech, ~170@wheels, ~200@crank
178TQ@4500rpm -gtech, ~185@wheels, ~215@crank

New Best!!!!
182.1Hp@5465rpm -gtech, ~185-190@wheels, ~215-220@crank
188.3TQ@3606rpm -gtech, ~195-200@wheels, ~230@crank

I used 2nd gear for this test.

Car feels extremely strong across whole rpm band.
Gtech results are with aero drag and environmental factors, because of this the results are a little lower than a dyno would measure. It says this in the gtech manual if you dont believe me.

wow awesome! now I'm really looking forward to my springtime mods. I wonder how much of a diff the warpseed cat and udp make, and if a fidanza flywheel would add much more oomph?

I went ahead and got the warpspeed metallic substrate cat only because i might as well change everything. All i know is with everything together i have instant throttle response and tons of torque. It showed i had about 180 tq from 1000 rpm and 188 at 3600 and it doesnt drop until almost redline!
I still believe that after i get a new knock sensor and 3 new o2 sensors and give the ecu a couple of days to recalibrate it should yield even better results.
