Please....Can someone please confirm the correct bore size for the HKS super dragger II cat back exhaust system and for the HKS downpipe for the IX?

After searching....Some say 3", 2.75" and others say 2.5"....

Please can someone confirm what is the correct internal bore size for this system?

Cheers!

 

the dp for the evo8 is 2.75 and the catback is 2.9. i dont know if that will help you.

 

Can anyone confirm this is the case for the IX, the actual internal diameter to DP and catback?

TIA

 

hks has 2 downpipes, one for their "turbo upgrade" which is 2.75" and wont bolt to the stock turbo/o2?

the other dp they have is 2.6 in diameter and bolts to a stock turbo/o2

as far as the super drager, im almost piositive they dont make it for the evo, the high power and carbon ti are 2.95 inch piping, with a neckdown both where it meets the cat, and inside the muffler canister

hope this helps?

 

So...If the HKS exhaust system is 2.75", would it be worthwhile changing this system to a true 3" TBE system?

Or if the HKS catback is 2.9", would it be worthwhile changing the HKS DP to a true 3" or is the gain minimal?
