Exhaust Help

[fububmc]

Just ordered the Star stage II turbo kit, and just wanted to have a new exhuast. The one I want is the HKS Turbo (Click Here to see it.), and this is a 60mm piping which if I am correct is about 2 1/4, and I also want to get a new catalytic converter from Random Tech. High Flow Ceramic, it states its for 2.0L Stock 2 1/4 Exhuast. (Click here to see it.) Just look under 98 Eclipse and got to Exhuast. Does this sound right and is there anything else I new or any suggestions or comments.

Thanks

May i suggest you go with a bigger diameter piping? the turbo guys come stock with 2.25 inch piping, and they get new exausts cause it restricts there flow. hell i have 2.5 inch, and im still NA... well most of the time... they recomend 2.25 piping for NA's, so if i were you i would go a little bit bigger. just a suggestion

i like hks exhausts a lot but if you are boosting and looking at a new exhaust, get a 3" one imo. you wont regret it
