I’m in the final stretch of a 99 Spyder N/T 4g64 to a 4g63t head swap with a 16g.
Sooo much is in involved. I have a huge thread going on it.
Everyone here has been extremely helpful. There is no way I could have done this without this group for support and knowledge.
One thing - I tend to order things and realize much later I messed up and got the wrong thing.
In this case it’s the catback exhaust I originally purchased, months back.
I installed it, went in nice and easy and looks great.
Then I got a downpipe. And this part was tricky because there aren’t much options for my setup.
I went with a RnJ performance downpipe. It’s listed as 3 inch to 2.75. It totally eliminates the stock cat. Which is not a big deal for me.
The problem is the catback I got fits the stock 2.25 cat, it does not fit the 2.75 downpipe.
I measured the flange end from the downpipe to the catback and it’s a flange for a 3” catback.
Now I have a few options.
1. Get a new 3” catback that fits.
2. Get a different downpipe that fits my existing catback/catalytic converter.
3. Modify the catback and/or downpipe to mate without any exhaust leaks.
If I can find a decent catback that won’t wake up the neighbors I would love to go with option 1. But i really would want it as silent as possible.
If I can’t find anything I will make option 3 work.
I’m not a welder, can’t weld for my life and don’t own one. And unfortunately don’t have friends or contacts that can either.
If I do end up going with option 3 it will be me getting a 3” to 2.5” (one of the Subaru ones) flange adapter and modifying it to fit the bolts.
I know going from a 3” downpipe to a 2.25” catback is not great. But I’m not doing this for racing, so it’s ok for now.
So my main ask;
Can anyone recommend a good 3” catback for a FWD 2g?
The more silent the better. Remember, it will be without a catalytic converter.
