Q300 too quiet! Help!

[EXCellR8]

I have a catted UEL and uncatted front pipe to the Greddy SP... really quiet and very little rumble. I might look for a different end section this spring. Possible single outlet...

That will likely be extremely loud with 99% of single exits. If you keep your stock front pipe it helps a ton.

I have heard the HKS single exit (with silencer I believe) with an Ace header and it sounded really good. Most others get tin can like and super loud (Greddy RS, Tnaabe single exit, Tomei, etc)

I know I still have the stock front pipe lying around somewhere, but I did just scoop a used UEL so I'll see how that sounds in front of everything else. I'd rather keep the Greddy AB since it's such a nice quality piece, but after the OFT flash you can't hear any rumble. Still just kinda hums along.

My current catted FT86 UEL is not as unequal as most of the non catted manifolds though, so I think that is mostly to blame. Shame, because they did a really nice job on the header; quality is top notch.

You should research this:

That dual exit version looks nicer... but $530 is a bit rough

Yeah,FT86SF does make nice pieces. I would venture to say if the UEl you just picked up is not catted it'll sound fairly nice on the Greddy SP. Hope it works well for you
