Exhaust Upgrade?

[conradtan]

I was interested in a 30+ hp upgrade with this product. Any advice?

It looked promising, for $1500. Is this a reliable source of extra power? I wonder if I will truly feel the difference.

Really? It's crap? Oh man... I thought it was a bargain. They make it sound so good.

That is called Advertising.

I have done some research on aftermarket exhausts for the 987. I don't think there are any really reliable numbers regarding the HP gains for making a change b/c there are many environmental factors etc... that impact the results for Dyno runs.

Generally speaking (directionally) adding just the exhaust won't get you anywhere near 30HP, more likely 10HP or less. If you add headers you will get better results, but still not close to 30HP.

Here are the main options I have looked at and some comments:

Fabspeed - nice quality but may cause some resonance. Depending on how aggressive you want the sound to be this exhaust can be pretty loud. For the 987 some don't like the way it looks from behind the car, the cans seem to hang lower (although they claim they don't)

AWE - heard very good things about this exhaust. High quality, more sporty sound, little to no resonance and not too loud. Shows HP gains.

Milltek - also nice quality with more conservative sound. Milltek never mixes the exhaust either, it is kept separate all the way through the tips. Usually costs $2000, but was on sale at suncoast for $1500 about a month ago. According to the Cayman forum the Milltek seems to produce the greatest HP increase, especially when using their headers.

Tubi - good quality, very good sound, but no known performance benefits. Also, I think this is spendy.

Just to reiterate, I was looking for the 987, so I'm not sure how this translates for a 986.

Based on my comments you can probably guess that I am leaning towards the Milltek, but won't be pulling the trigger just yet. If you want more info on relative HP gains and sound etc... Check out these links.

hey conrad..here's what i learned after I got over the HP Mod bug...the most that i will gain are 10 hp unless I will go all out and feel the difference w/c is engine swap and it will cost $10k and the most important thing that i learned is..
-Invest your money on D/E
-Go Autocrossing
-Sign up on next Thunderhill
*hopefully someone will chime in in regards of the 3 above

It's all worth it...by doing this, you will really feel and learned what your Boxster is made of!

i haven't done any of those 3 but will AX next month @ Monster Park and I know some boxster owners who've done it and hearing what they would say about it makes me want to forget about adding mods

x1 for Bruce

I'm sorry, D/E, AX? I'm new here so I don't know all the acronyms yet. Hehe... So seems like bottom line, don't do anything to my car that does not cost 5 grand or more, or else suffer "check engine light" problems and the like...

Man, I thought this was going to be easy. Guess nothing good comes easy.
