So you're doing headers blowing through stock 400 cell cats? Doesn't seem to be the best approach. Maybe should've gone Soul 200 cell cats FIRST and see if you like the sound??

I guess I’ll take one for the team... if the cats need to be replaced they will be

I would counter, what's the point of going to 200 cell cats if you're blowing thru that atrocity of a stock header Plus, I've already shown how equal length headers change the sound quality and volume compared to the stock log manifold header design.

Still waiting..
Ordered Sharkwerks and VekTor on 5/7 - but both are being ceramic coated so thats where the delay seems to be for now.
Ordered tips on 5/10 and they are still with Jet Hot...

BTW - checked with Cobb tuning, with this setup I will need a Pro-Tune.

basic666

what tips did you get? are they from soul?

Cyberbug

Yes, waiting to get them back from jet hot

Looks like another month before I have them

basic666

What type did u end up getting? I just grabbed double walled 4" from them, as well as cats and akra diffusers

Are you planning to install them yourself? I am not looking forward to taking my bumper off and struggling in tight spaces again lol

Cyberbug

4” DW, ceramic coated

going to install myself

bumper does not require removing, install is not that bad. I have all the tools needed and then some.

When I spoke with the Sharkwerks guys they said you only had to loosen up cats but don't need to completely remove them. Do you have a stubby wrench for the one bolt that is tough to get at; curious how you plan to attack that.

basic666

I'm doing the diffuser too so bumpers are coming off for sure! Hope that makes the cat install easier.

From my experience, a swivel joint and 1/4" tools should be able to get you access to everything in the .2 car. I mean, there's nothing harder to reach than that 1 freaking bolt between the header and turbo

Cyberbug

did a sound level baseline, don’t mind the numbers its just a baseline. The mic is 10” from the tips so numbers are high.
but I can do a similar test after the install for comparison

If you have an Android phone, can you download the Spectroid app and get the full FFT measurement? It'll measure dB across the frequency spectrum.

Cyberbug

I can do that too

Cyberbug

By the way, I have no clue overall about that app, I did see your analysis thread earlier.
what exactly would you like me to capture

spdracerut

Just have it running on the same setup as you had the dB meter and have video going on it. Once you play with it a bit, you'll see how it works. You can change the scales in dB range (upper and lower limits) and also frequency range by using your fingers in standard screen zoom type fashion.
