lol true true. i was just wondering the expected hp gains on the mod list.

The only way to get a close estimate is to find someone with the same mods who has numbers.

I wouldn't chip it though, I'd look into learning to custom tune with HPTuners.

lol@chips.

low 14's

so I'm losing time In my quarter mile? Lol. I had a pass of 13.9 in the summer just intake and exhaust

So.. I just re-read the OP.

You said you had full exhaust but you just ordered a downpipe... Then headers...

LOL

You'll understand why I said LOL when you try to install it all. Good luck.

LOL whooops...for some reason i was thinking stock even wehn i was responding.
now im gonna say 13.4-13.6. chips are a ripoff. go full out custom tune.

without a tune your looking at about 265 hp and 280 tq to the wheels. after the tune with all the mods your looking at 275ish. dont chip the car. go with hp tuners, a lew tune, or full dyno tune by a respected shop. you'll never see low 13's without drag radials. a 13.9 bone stock is an awesome run but these things are hard to launch with all that tq. im going to bet you wont see any more than a 2/10ths gain without DR's. i could be wrong though.

ok? Lol or u can tell me what I'm doing wrong? I guess its funny to see someone trying to learn and people put them down. Why post negative stuff. I dont get that . I dont ask questions to hear negative responses

06gpgxp33, did you get a cat back exhaust? catback is from the catalytic converter back. a downpipe is basically the catalytic converter itself. the best route to go would be to do the entire exhaust at once. headers 1st, then bolt up, or welde up the DP, then rest of the exhaust. if your exhaust is a cat back and bolts on then dont worry about explicit-spades responce. if it is welded in place then you will need to have it cut off. when you say "full" exhaust that usually means headers and all.
