okkkkkk so sorry if i come off retarded and hope around on topics....

so i uninstalled the topspeed 2.5 n installed the oem catback exhaust i left the testpipes n topspeed ypipe on..

so i turn it on and its hella quieter

so i do my test run down this street i always push my car...so im riding 1st gear at 2krpm n n slam it HOLY F*** THE CAR PULLED RIGHT AT 2500K WAY HARDER THEN IT USE TO AND RUNS WAY QUICKER THROUGH GEARS.

no lie it felt a lot jerkier at mid to redline but i kinda noticed or maybe it felt the same at 80+mph where it kinda evens out not necessarily die out..

so to concluded this or wrap this up the cars bottom to redline felt hella smoother n quicker...now my question to open this topic up is WHY I almost wanna kick myself for buying a cat-back exhaust

now my problem i wana just run utec and get my car tuned by perfomance factory in orlando while keeping the oem catback with current mods in sig...n then later purchase a catback n retune n dyno to see where i lose n gain at....


advice please


thanks.

 

Congrats on your results.

 

off topic but, have you guys started selling the xyz pipes yet?

 

ok ok lemme edit it really dies down at topend like into 3rd to 4th it seems a lil less pushier oppose to my aftermarket exhaust where my car was able to allow more free flowing air at top....

 

come on peeps need some opinions
