haha I was gonna ask you for a video of your car, good looks it sounds insaneee. Anyone know any good tuners that do uprev in Jersey? Probably going to be a while before I tune it tho, still have a lot of modding to be done. Envy, big difference in how the car ran before and after a tune? I know with my Talon heavily modded, it ran lean and like **** before a tune.

Loosing your stock exhaust for a better flowing one does help considerably. My best 1/4 mile time was a 13.3 with the stock exhaust and a 13.4 with my dual. Difference being is the 13.3 was in October with cooler weather vs May with high humidity and higher temperatures. I'm hoping to run a 13 flat here in a few weeks with cooler weather heading here. Will post up times in a few weeks

i agree with the OP. straight pipes does feel like you're missing some TQ on the bottom.

on top however it feels like it pulls harder than when i have my mufflers on.

running full 2.5" Fast Intentions non-res TP and non-res CBE with custom short tails to match up with the FI system. with FI tips of course

been running mine since march, with a small exception of putting the mufflers back on for inspection.

have not been on a dyno nor re-tuned. everything runs great but the butt dyno does report a slight delay/tw loss on the bottom. WOT feels great so i dont see a AFR issue.

i mean i do have my own personal uprev i guess i could fire up the laptop i test it out lol

I'm a little confused on this one like the OP, currently I'm running only aam short tails and k&n drop ins with z1 post maf tubes. From what I understand the short tails causes a loss in back pressure which takes away some low end torque, which honestly my butt dyno didn't notice lol but I did notice a small gain up top because it revs easier. My plan is to pick up the AAM s line midpipe to go along with the short tails. Now they claim that is pretty much an increase in 20whp and torque, but from reading this thread it seems like I would lose power? Isn't the AAM s line and short tails combo pretty much a straight pipe catback I guess? Thanks fellas

FPenvy

with my regular set-up my only backpressure was my mufflers and it was a monster.....still is

i was tuned at AAM with my original set-up (in sig still) at 324whp and 258wtq.

i feel that now without the mufflers is the only reason i feel the slight loss in tq. and again it's butt dyno and it may be my ears playing tricks on me.

i say this since now with it being so loud so quick my brain may be telling me i should be going faster than i am based on pure sound......if that makes sense?

i have ran the 1/4 in back to back weekends with and without mufflers recently and saw no real differnce in my ET's and other numbers soooo idk.

Dude! You hit the nail on the head! that's rxsctly what I predicted. When I was stock muffler I felt slow since it didn't sound like I was going fast. With mufflers on I felt way fast since I heard the engine revving, and now I'm straight piped I still feel fast but when I rip it , it feels like my car is going to go to the moon, But it's not any faster than before.

bryan_Z34

I was just open mid pipes for like s week . I felt no difference at ALL. and when I crafted my own short tails with helmholtz, I must note that now is when I feel the loss.

Shawa

Yea def interested in the FI hfc's, always hear great things about them. Guess I'll just have to see where the car is when I get the s line midpipe done, along with short tails and the drop ins with tubes hopefully I'll be at 300 whp.

FPenvy

you should hit 300whp with that setup and probably over 300whp with a tune.

remember i baselined pre-tune at 309whp with just my exhaust/intakes.

Thanks bro I appreciate all the help. After the exhaust mods I'll start working on the suspension!

FPenvy

anytime.
