I have 87 NA with racing beat downpipe that goes to racingbeat presilencer. Car exhaust fumes are pretty strong which i know is common with these cars.

Question 1 : If I add a bonez high flow cat to my system will it reduce this smell any ?

Question 2 : Can I install the bonez non turbo cat to my racing beat down pipe without buying the racing beat header and just extend the tube to fit to my catback without any problems?

Also im talking bout the Bonez on rx7.com this one also has the tube for the 5th and 6th acuator function. Anyone have expeiernce with this working on their builds ? Thanks

The RB downpipe and Bonez cat are the same setup I'm currently running on my non-turbo S5. There is no exhaust smell when using this cat. The Bonez cat is the same length as the RB presilencer. Therefore, it's a direct swap.

You are the man . Thank you for that picture.

Would you say the cat is quieter than the RB presilencer? or louder

That's the question that I was going to ask you once you get the cat installed. I've always run a cat on my car to eliminate the strong exhaust smell. My guess would be that the noise levels are about the same, but that's TBD.

I wish I got a cat from the start. Didn’t relize how bad the smell would be . Especially driving around creates unneeded attention and smell that honestly makes a lot of people complain lol.

and yeah I would guess it’s about the same as well but I will update this and let you know when I get it. Might be a couple months tho. In the process of doing some bodywork and repainting the car. So once I get that done I will most likely buy the cat.

thanks for the info man , stay safe !
