Not really jumping into the HP wagon (yet ) just looking for minor performance and sound mods.

So I think I'm going to buy the chip and a g pipe to bypass the final muffler because I don't see to much of a benefit of removing the cat.

I am a bit confused on two things though if someone could chime in I'd appreciate it, I searched through some threads on muffler bypasses and some people would say they did the secondary bypass but they didn't want a g pipe?

I thought a g pipe is a secondary bypass, and for a daily driver should I leave the cat on?
Kinda important stuff before I buy a 300 dollar chip

Oh and is the fabspeed g pipe compatible with the stock primary muffler?
Ugh the more I read the more I change my mind now I'm not sure if I should do a primary bypass and keep the secondary muffler

Yes a G pipe is the secondary bypass

No need for a Cat daily driver or not, unless legally required

All G pipes will be compatible with the factory parts that remain

G-pipe has a nice deep growl to it, cup pipe (i.e. primary bypass) has a higher pitched wail to it. Personally I have a G-pipe and absolutely love it. Supposedly the cup pipe nets a bit more horsepower gain, but we're talking in the low single digits difference (probably unnoticeable from a performance standpoint).

My G-pipe was done by a local muffler shop for MUCH less than what the aftermarket companies want for their g-pipes...a very simple job for any decent exhaust guy (actually I think mine was done at a Meineke and they did a fine job) and you've got a one day turnaround as opposed to ordering the part, waiting for it, etc. etc... Normally I'm a very DIY kinda guy, but in this case I think its a win-win having a local place do it.

Yeah I was thinking about having a local muffler shop do it 300 for a U shaped pipe does seem ridiculous

I'll throw in my 2 cents:

Based on my own experience, you may be best served to do one mod at a time. For instance, maybe just try out the primary bypass pipe and see how you like that on its own for a while? Piling a few upgrades in all at once can be less informative, not to mention more expensive.

Good luck!

I got a RUF primary bypass 1st. Really love the way it sounds. Nice low rumble at under 1500 RPMs and a nice full powerful sound above 4000. I followed up with a SW chip. The chip made the idle perfect and throttle response better.
I agree that you should do the exhaust mod's 1st then chip it. I also told Steve Wong that I always use Shell 91 and I believe the chip is tuned to such.
Now I think she is just perfect.
My 2 cents. Cheers

Porsche utilized a primary bypass (cup pipe) for its Cup cars. I'm not aware of a Porsche-based secondary bypass (G-pipe).

I thought the Porsche Cup cars used a primary bypass and a secondary bypass without a cat. I could be wrong though
