hey guys just want some opinions on this setup or if it will even work considering the N1 eliminates the Cat. Let me know what you guys think or if you have a better exhaust setup suggestion. Also if the N1 racing exhaust is even street legal.


I have a Stock '93 RX7 t/t
and was looking at this setup
Bonez 3" Stainless Steel Performance Converter System
A’PEXi N1 Racing Exhaust or GReddy Japanese Spec Racing Exhaust (you tell me)

heres the site they are on: http://rx7.com/store/rx7/fdexhaust.html#convertersystem

Thanks,
Justin

 

If you are running stock ECU then I’d say no. If you have a way to keep the boost at 10 you should be ok. As for street if you are running cat less no but only way the cops would know is if they crawled under your car. Also cat less the car is going to be loued and defiantly over the DB limit for street use.

 

Thanks Keep them coming

Your opinions make the difference

 

There's nothing wrong with that setup. Essentially you're running a downpipe (normal), hi flo cat (normal), and an upgraded catback. It's all fine.

 

That setup will be fine as long as you control boost to 10 psi (using a manual or electronic boost controller). I would STRONGLY recommend not going with the N1 exhaust, as it is ungodly loud and sounds like ****, IMO.

 

I have the same set up but with a hks down pipe and I love it. It is loud though, so if you have nosy neighbours be prepared for complaints when the thing is warming up at 5 am.

 

thank you for your help.

But I've heard the apexi N1 eliminates the cat. does it? and if so there is no point in buying the high performance cat right? should i just buy a downpipe?

let me know what you think

Thanks alot ,

Justin

 

Get a Racing Beat Dual tip. Super high quality, sounds great, looks good too. Not as freaking loud as the N1. More mellow and a little lower. Not too loud inside the car either. I debated this for a long time, I like the look of the N1 dual but, again, too loud. I know some people with the N1 and when they drive away I'm like, Holly crap that is freakin LOUD!!

 

haha thanks I'll definately take that into consideration.

 

The N1 does not eliminate the cat . The down pipe well eliminate the pre cat , but you well still have to have something in between the down pipe and the cat back N1.

 

I absolutely agree with this statement.

And I concur with this one.

 

ok thanks guys you've been a great help. with the kit listed above the:Bonez 3" Stainless Steel Performance Converter System it comes with a down pipe and performance main converter i believe so im pretty much set with what ever catback i want right? along with that system.

thanks again you guys are awesome.

+1

 

I say Blitz Nur Spec with a precat and high flow cat. Its a very deep note and looks awesome.

 

It doens't replace both the main cat and the cat back, just fits right in where the catback used to be. With a full exhaust (DP, MP,) and that cat back (N1- single or duals) you will get a very loud and deffinate 2 stroke sound. The resonated mid will help but it's pretty much straight through.
