I love my rb turbo back, its super quiet at lower rpms and then screams at wot, the best of both worlds imo.

 

is the cat converter i need the one on this site that says this for the description also what is the stock pipe size for the pipe right before the y pipe splits http://www.rx7.com/store/rx7/fcexhaust.html
Just what’s needed for your custom RX. These catalytic converters are the same quality units used in their direct bolt in systems. Recognized as the freest flowing and most durable of all the catalysts, you simply can’t go wrong with Bönez. Available in a variety of pipe sizes.

Bönez Performance Converter (Blank)

 

anyone

 

91mazdarx7: Please describe what you want to do and what your problem is.

 

i want to replace just the cat converters and have a bonez hi flow cat converter to replace the old rear converter and a straight pipe in the place of the front converter i got an answer saying my 5th 6th ports will still open with 1 hi flow cat i just need t know what bonez hi flow converter to get

 

Since you mentioned 5th and 6th ports I'll assume your car is n/a. Get the "Bönez Superflo System". It has a downpipe, presilencer and high-flow cat:
Go here to see what it looks like:

Or at the RX-7 store: http://www.rx7store.net/index.asp?Pa...ROD&ProdID=615

 

My FB shot flames from under the hood. Beat that.

 

i just want a hi flow cat just 1 cat to go right in front of the y pipe and a straight pipe to in for the cat by the manifold

 

Dude you don't make much sense. I posted TWO links to a straight pipe from the manifold to a high flow cat. The "Bönez Superflo System" is what you want (atleast as best as I can understand what you're trying to say) Here's what it looks like:


The only possible misunderstanding that I can see is that the system has a presilencer. It's as good as a straight pipe.

flamingroids must have posted in the wrong section...

 

ok i was only going to buy a hi flow cat no other pipes and put that in the place of the rear cat then use a straight pipe and mount it in the place of the cat by the manifold i was looking for a cheaper way but i guess ill just have to get that but it says it is for the 5 speed and 86-88 auto and i got a 91 auto so this item wont fit it am i correct

If you're going to custom fab a pipe to go to the cat then why couldn't you just use the Bonez TII main cat or any other cat for that matter?

 

i might have to do that but the more i look at that super flow system i want it but it says itr wont fit my car mines a 91 auto and i only see the 5 speed and 86-88 auto does this mean it wont fit? please answer id like to get that if i can

 

Why don't you call them and ask if it'll fit?
