Fat shots vs SE

Mr Schultz is exactly correct, try it without any discs to see how it sounds.

Also, depending on specific application, the closed loop Fi will adjust to run the same AFR as stock, so you can effectively try different combinations to see how it 'sounds'.

Great!. Any backpressure or other issues one should be concerned about?

Not with the stock CAT equipped head pipe-run it.

Thanks.
