i just installed :

Tomei headers & test pipes
Fijitsubo Y-pipe
Blitz Nur spec cat-back


the sound is nice in the low RPM ( below3000) .. just amazing.

but after 3000. i get a sound just like the M3. and abit louder. i dont really like it much,. specially from the inside.

i am thinking to put back the OEM cats, but i was told that they wont fit the Tomei.

anyone have any input about this?

i searched alot and never found an answer.

 

wow... not even a single reply ???? :S

ok thanks for all who at least viewd the thread

 

If you replace the test pipes with the OEM catalytic converters it will sound like this...

...varoooooooooooom...chuga...chuga...varoooooooooom...

 

test pipes usually fit just the same as OEM cats. why wouldn't it work?
