I think I've decided to buy the Bonez Turboflo system from RX7.com. I want to keep a cat in the system and keep the car street legal. Does anyone have experience with this system? How much better is the RB turbo-back system (which doesn't have a cat)? Is the 2.5" pipe on the Bonez system big enough?



All opinions appreciated! B)

 

i personally think the bonez systems are good but over priced. i would go with a HKS DP 3" dp to just the bonez cat. that is the system i went with on my OLD 87 TII. it sounded really nice. the BONEZ DP is a cheesy POS!!!

 

Where can I buy the HKS downpipe? Any trouble bolting the 3" DP to the Bonez cat? Isn't the cat 2.5"?

 

it bolted up fine. you can get it from rotormotorsports. then you can buy whatever catback you want you will also need to get your ECU reprogrammed or a FCD. i highly recommend ECU reprogramming it kicks ***. i think E.L. prototypes will do it for $300

 

this is a pic of the POS bonez dp





notice it is on the first of the three pipe sequence. the HKS goes from turbo to the main cat and eliminates the second pipe. when i bought that i was like WTF this is crap and promptly sold it

 

ahah, that is mad chessy

 

Rotormotorsports doesn't list the HKS DP for the second gen. Do you think they still sell it? Anybody else sell HKS?



Corksport lists a 3" stainless DP for $230, but no pic. I don't know if it goes all the way back to the main cat or not. Any thoughts?

 

they can get the HKS dp. just pm www.rotormotorsports.com on the forum
