Convertible Exhaust (L99) - What to do W/ Resinator - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Ryanbabz71 · 06-22-2016, 07:58 PM

Ok to cut to the chase, I have LT Headers and Flowmaster Axleback. I also have the butterfly valves welded open.

What is entailed in getting rid of the resonator(s). I bought a magnaflow X-Pipe but it seems like there is some good modifications needed to make it work.

The photo is the convertible exhaust I found online (not mine). I would like to eliminate the resonator in the middle. What would you do or have you done?

Thanks!

I just bought an M6 exhaust and swapping my axle back to that. Just like in your pic.

Here is my system, 3" all the back including x-pipe.

Thanks is that custom? Did you have a shop do it?

Complete exhaust is made by Stainless Works ( see their site) and installed by RDP with a dynotune.

I took my resonator off and istalled an magnaflow true x pipe in its place, just added more pipe to fill the gap

How does it sound when the AFM kicks in?

Not sure if its me who you're asking but mines sound real raspy when the afm kicks in, its not unbearable but it is really noticable. You get used to it it's not that bad, I can still have a normal conversation inside the car with no problem at all

Abelardoo_12 & Ryanbabz71, thank you both for your replies. Yeah my message was for whoever wanted to chime in.
I have a Borla axle back & have been on the fence on deleting the Big O resonanator because of the different threads I've read about on the AFM. So that's why I asked about how it sounded. Thanks for your replies!

Thoughts about adding NPP exhaust? Can I just bolt on (minus a new rear diffuser)

Ryan

olblue75 · 07-10-2016, 01:16 PM

Ryan I have a set NPP Muflers if your interested and there's a guy in the exterior classifieds that was a 1LE diffuser for 80 bucks I think....

Did you keep the stock mufflers in your setup and just replace the resonator with the X pipe? Any recordings of your exhaust sound online?

Just order this part below(see link), I run this with Lingenfelter Axle Back and it sounds great. Even with stock mufflers it will increase tone significantly. I started with the axle back and did not like the sound, still too quiet so then I did some research and found this. $139.00, a sawzall and about 30 minutes and it made a night and day difference, car sound mean now. It's inexpensive, quick and easy and no o2 sensors or anything to worry about relocating or turning/tuning off.
