EL header + stock FP + Perrin 2.5" resonated

I run the Ace A350 which is catless. The stock FP obviously retains the stock cat. No pops or weirdness. Sounds very racecar

I can attest to this claim. The ACE headers give it a very good sound

It's unfortunate that I can purchase two Tomei headers and still have $400 left over for the price of an Ace

Look at JDL 4-2-1 EL cheaper than ace

Dont worry too much about what brand header you get. 80% of the gains are coming just from the fact that you ditched the cat in the header

Not surprised. Those are a totally different style of catback.

Yeah. I Agree.

I swear to goodness mine didn't sound that bad. Maybe it helped that the header was CNT rather than expensive well thought out runner design, and UEL

To be more specific, it happens with exhausts that utilize a muffler that uses baffles/chambers to reduce unwanted noise.

Most of the straight-through, perforated designs with fiberglass packing won't have as bad of a rattle issue as a stock design.

Here's a clip for reference. There are no cats on this setup, and even with the Fujitsubo front pipe you still have a weird rattle at higher RPMs (and it's more pronounced under load).

The same exhaust had no issues with either a stock cat or the Apexi header w/ cat.
