2.75 is going to take away some power in the low end... but it'll help in the top end. 2.25 and 2.5 is definately better suited to the puny k03... but I really don't care. Get miltek, it'll look and sound amazing... and it'll stay with you, even if you upgrade to a big turbo.

 

i bought a high flow cat and a remus muffler that way for now i can go with 2.5" and then when i go bt i can upgrade pipes to 3"

and from what i hear.... Remus does sound amazing. im going to post some videos when i get mine on

 

Which high flow cat did you go with Ryan?

 

i ended up getting the magnaflow for right now due to the price... i think it was a total of like 278 shipped, somewhere around there... compared to the labree at like 700 lol.

(i still need a cat for emissions here in ny so i cant do a test pipe... or maybe i can but for now the HFC will do me fine)
