If you do a full setup from front to back meaning better flowing headers be it because of fewer CELLS or No Cells, Delete the 2 rear Cats and put on a non-baffled muffler. It will sound like a completely different machine. at least for me it did. I dont' think just the By pass pipes is enough maybe you could do some before and after Vids i would be interested. Also I don't think 8 hp would be that noticeable not like 20-25 hp. good luck

as I live in CA, there is NO Way I can go to a totally catless system.

I'd have to have a system with at least the high flow cats built into the front headers. then I could do the cat delete midpipes and change my muffler. on a system like the NHP, that setup is about $2000, which is more than I care to spend on exhaust...

and I have doubts I'd really get 25hp on my 2.7L from that setup.

i'm in the process of picking up a tequipiment PSE muffler to replace my "pedro" muffler...which as far as I know, is no more free flowing than stock, it just sounds better.

"and I have doubts I'd really get 25hp on my 2.7L from that setup."

Me too, I was able to pick up about 25hp on my 2.7L, but that was with new intake, complete cat-back exhaust and custom ECU chip. That makes for a very expensive 25hp......

honestly, i'm not gonna drop othat much money into my boxster for power upgrades....

i'd rather spend the $500 on suspension upgrades or something. i already have 18s and M030....

maybe a techno brace?

techno torque? maybe that woudl be a better way to put some money into the car?

would the reduced weight of the pipes (3.2) unbalance the car? would one have to remove the spare.....or? to balance it?

I don't think you'd have to remove the spare, but it's a fantastic excuse to do so.

Once I learned the hard way that a rear tire will not fit in the frunk, the spare became expendable. I now carry a patch kit, a small compressor, and a roadside assistance membership card instead.

The Fabspeed bypass pipes are my favorite mod so far - well, that and the Yokohamas.
