Gutting the muffler

[VR_Berly]

i have a vr 6 and im after bit of a note from my exhaust. I was wondering if gutting the first muffler would create a decent sound. Has anyone done this before?

what state are you in? that'll determine the fine you can get for doing something that will hardly change the note and provide minimal power gain.
It's about 10k in vic....

dont do it, its only 250-400 for a cat back, u'll get ur note and its done perfectly.

done be a tight ass and do it properly

[leigh 7005]

just take rear muffler off and put stait pipe should give a decent note $300 $400 is hard to get when you dont have it

whats wrong with waiting til you can do it properly? save that little bit extra..

finnnnneeee! ive been thinkin of runnin a 2.5 cat back system with two hot dogs, the first being longer than the last. What do you's reckon?

[DannyboyDS]

anything is better then gutting a Cat converter, that is what you proposed to do yeah?

A muffler can't really be "gutted". Most people assume that you mean the cat when you start saying "gutted".

As has been said above, the fine for gutting/removing a cat converter is up around 10k when you get caught. It will not improve the note or give a power gain.

Removing a muffler is relatively legal and will give your car a louder tone.

I wouldn't bother putting a "hot dog" in myself, simply removing a muffler will result in a significant boost in noise. Possibly more than you expected and long highway driving can get to be a drag with an excessively noisy exhaust.

My advice would be just got a 2.5" cat back exhaust and talk to you mechanic/specialist about whether or not to include the mufflers.

Good luck.

if you can its best to hear another exhaust the same as you want as each different muffler / hotdog affects the tone, ever so slightly but u can notice it. there is a massive thread in the "V6 development and modification" section on exhaust notes n setups, check that out for a heap more info
