2014 L99 exhaust setup!

[tekteq]

My '14 SS doesn't sound aggressive enough so here's my planned setup:

SLP Loudmouth 1 (On its way)
Cold Air Inductions CAI (On its way)
Summit Racing X-Pipe
TSP 7/8 headers

If I stick with the stock cats (I live in Cali so in six years everything is going back ) will I lose performance? Anyone else have a similar setup? Thanks!

You can't keep stock cats with long tubes.

What high flows do you recommend?

Pretty sure you can get HF cats from Texas Speed.

You might want to re-think some of this. You've mixed and will need to match different manufactures such as the X-pipe in the middle. Why not just get a complete catback? Then by headers and cats to mate up to it. Since you will be tuning AFM will obviously be tuned out but you will get quite a bit of drone with this setup, but that's a personal preference.

Get TSP headers and HFC, and a catback of your choice. I had the Borla S type and drone was terrible. Got the SW Retro now and the drone is gone. My .02 cents.

If I got a catback setup I would have to opt out a couple hundred more and sell the axleback. Is it the headers that will cause the drone or something else? and has anyone else on this forum have any success without a catback system? I can live with drone if it'll save me a couple hundred (I'm a mostly local driver and I have my speakers turned up high most of the time anyways).

Ok, then go the other way around. Get headers, cats and X-pipe from Texas Speed (can't believe I'm saying that as I'm not a TS fan LOL) and just hook them up to your axle back. It's the axle back that will be producing the drone. The headers will make it much louder. Most people with cool exhaust like to listen to it over the stereo.

In fact TS sells all the SLP stuff you would need.

Sounds like a better plan:P. I think I'll get the x pipes for now and see how the drone is with just the x pipes and the SLP exhaust, then go about deciding whether I can handle the header drone thanks man!

There you go... and you won't have to tune and lose your drivetrain warranty.

You will have to deal with the AFM noise when it switches to 4 cylinder mode, but there are ways to deal with that if it bothers you.

Getting the trash cans off the rear and some good sound from the axle back is #1 then.

I was actually planning on using my Rode NTG-1 directional microphone to record stock and modded exhaust sounds to give forum members a more accurate representation on how they sound! (much better than iphone mics lol)
