Deep sounding cat-back to suit catless UEL headers

[Arcade_West]

Hi all, looking for a deep exhaust to suit Tomei UEL headers and catted front pipe. It's hard looking through videos on youtube of heaps of different catbacks, as many are just on stock headers.

So i'm looking for something deep, with no rasp or drone. Beofre it's mentioned, yes I have heard the Q300 and perrin resonated with UEL headers, both sound very raspy when revving. Any ideas?

Neither sound raspy? I own the Q300 knock off and there is zero rasp with UEL cat less headers? Maybe it's the recording or perhaps the tomei as I have Borla?

I'll try getting a video of mine today

Both of these are raspy as shit though:

Perrin resonated raspy when revving? Mine isn't at all. Unless you heard someone with a catless front pipe, then possibly, but neither of the catbacks you mentioned are raspy normally with a catless UEL header and a catted front pipe.

i'm not asking for a debate on whether or not these are raspy, I have already stated in the original post that I do not want either of these exhausts

No idea man I have a full catless setup too. I'll post a video later. The Ikon motorsports exhaust could have a different resonator.

Not sure why, but that setup sounds a bit raspier than others I've heard including my own. I think these clips are probably more accurate.

The videos that you linked, something isn't matching up, like someone said one is an unresonated one.

The ones just above this post are more accurate. The Perrin and Q300 are two of the most popular exhausts for this car in regards to sounding great with a catless header, or really super quiet.


If I find some time, I could video my setup with the JDL UEL, JDL OP, JDL catted FP, and Perrin 2.5" resonated. There isn't a hint of rasp throughout the entire rev band.
