aftermarket intake, stock header and cat
i got the hks hi power with a megan header and i replaced the cat with and oem one
And the megan header.
nice! you got a sound clip?
no i dont have one but i can tell you that it sounds amazing. its very deap and its not raspy at all. the install was easy they supplied me with all the harware and gaskets and it does no hang low. it tucks up tight. 10/10
RS*R GT2 with a 22" magnaflow resonator
and heres a video clip
sorry to bring back an old thread and i will probubly get hammered for it but is there an 2.5 in cat backs out there or does have to be custom?
i believe thermal r&d makes a 2.5"
i just checked there website and all there was is a 3" turbo aplication, but thank you for the info please keep it coming
Nice! Brand new OEM or HKS Sport? Kind of hard to tell from the angle
is there a real noticable feel in power when you use a test pipe instead of a cat???
[QUOTE=boostEquipped;1863209]2.25" piping to a j’s racing replica turn down muffler, also a newer cat off a 2000 si if that makes a difference, stock header and aem short ram. sounds real mellow and deep with normal driving. once you get on it it gets loud but not annoying buzzing loud.

where’d you find that muffler at?
wow i guess dyno’s dont lie … cool i guess its a nice aftermarket cat for me to replace my old oem one
hha Neither… 22" magnaflow with HKS sport tips. got rid of the old HKS because it was hurting HP. this one is 2.5" mandrel bent from the headerback, no cat
Sweet! Looks real clean 
was your 2.5" piping custom or a kit? i am looking for a 2.5" kit if anyone knows of any.
