Muffler Mod Pipe

[RascalRuss]

Hi all,

Looking for some advice, I am thinking of carrying out the muffler modification that is I believe well known now, where by by-pass pipes are fitted to divert some of the airflow directly to the tail pipes rather than in to the muffler.

Now one set of instructions I found to carry this out suggested using 1 & 1/8" pipe, however my local store only had 1 & 1/4" pipe which is slightly bigger. My question is, is this to big, will it end up sounding horribly loud with this size pipe allowing so much gas flow to miss the muffler?? Im just after a nice sportier sound (my friend just picked up his Porsche Spyder RS60, and the sports sound from that is just.........wow wow wow wow, even with the sport muffler mode turned off its still incredible)

What are your thoughts and recommendations guys, would really appreciate some feedback

By the way, I am running a MY 00 Bosxter S

Cheers

The UK guys have a special deal on this. http://www.boxa.net/forum/index.php?showtopic=30968 There was some talk of being able to buy a kit.

Tool Pants,

Thank you kindly, seem the 1" 1/8th I have should be ok, a little bigger (3 mm or so) but I can fit some baffle plates inside the tubes if its too much.

Thank you again

I have the muffler with the bypass pipes and it still wasn't loud enough for me. Keep in mind, I was looking for a nice sound, not overly loud or such. I heard Boxsters with aftermarket mufflers and didn't like the exhaust note. In addition to my modified muffler, I added Fabspeed secondary bypass pipes and finally found the sound I was looking for. Nice and deep at idle, good rasp when the varioram comes on, but no droaning or resonance when cruising.
