Wanted-964 g pipe/cat bypass/mid section bypass
- Thread starter sambo964
- Start date
I have heard a 964 with a straight through exhaust and believe me, whilst it sounds glorious, it is BLOODY loud.
A cat by-pass and a cup pipe (replaces the central silencer) will take you up to about 107/108 dB which will prevent you getting on almost all track days. I have that configuration plus a Cargraphic induction and a specially made silenced exhaust tip and just creep onto the noisy track days (which are 105 dB) with 104 dB. With the central silencer back in place of the cup pipe, I am down to 99 dB.
I would imagine the straight through configuration would be about 112/113 dB. Bear in mind that an increase of 3 dB A is the equivalent of doubling the volume.

what do you think would sound better?
1. leave the cat in, straight thro pipe instead of middle section, and g pipe on the end?
or
2. take the cat out, leave the middle section in, and use a g pipe
any suggestions?? or going a bit to loud? i have personally never heard one

Getting rid of the Cat and the centre silencer will shed the most weight from behind the rear wheels (and still keep the sound within reason) which will help the handling the most. If you don't intend to track it regularly, then it's up to you.
Personally, I'd buy the cat by-pass, cup pipe and G pipe and play about until you find something that works for what you want and then stick the remaining bits on eBay.
