Which 4 inch single shot?

[434nova]

Looking to replace my Pypes 2.5 exhaust with a 4 inch single shot exhaust. Not sure who’s to get rjc or gn1? Trying to save a few #s with the single shot exhaust and get a different exhaust tone. How do they sound over the 2.5 Pypes with race pro mufflers? Anyone have any issues with fitment? Looking for some reviews. Thanks

Here's what the RJC system sounds like:

Installing a GN1 now and so for it fits well.

Thinking of welding it instead of using the bands.

Is the gn1 completely polished? Any idea on the weight of the system? Thanks

Parts of the tail section is not mirror like some others are.

The muffler is.

The front part (from the four-bolt to the muffler) is not.

RJC with a flopro muffler, cuts out the drone

I have the RJC and modified it to accept a 4' Oval Borla XR-1 Race muffler. The longest muffler I could get. It sounds really mean...but my car idles different then most. Big cam rumbles pretty good.

I got the 4" RJC. I put a 4" resonator where the factory catalytic converter is to tone the noise down, (I find that it was too loud, especially cruising late at night and coming down my street at 1:00am), and also have it there in case I get a cop that is looking to write tickets....
