Yep, I hear ya, but not everyone thinks the same way you and I do.

I would agree, but then again, I'm not likely to buy either one due to the increased noise.

I vote 7whp at $500. I want to keep my car emissions legal, and without CELs

I will go with the DP/CAT AND 7. Let me know when and how toorder.

I'm definitely interested in the mods you've put together, including this one.
For this one I'm more interested in balancing the 7hp gain against making my Sky sound too loud/agressive/nasty - I want ot maintain a low profile

.

I remember this post:

I'm meeting up with skycruzr tomorrow to hear his new GT Exhaust 'in person' so I can decide on that one. I'd need to hear this as well before going for it.

The intercooler will be done *soon*

Of course youll have CEL. lol. You have no cat! You most likely have "cat efficiency" code.

jans · 08-31-2007, 05:14 PM

Yes'' that is what i have,is that code to change in the ecu /software ?

Yes, you can disable it with software tuning. We don't disable any CEL without telling you. Thats just an easy way for someone to sell you a crappy tune or product. If its running right, certain CELs should NOT come on.

GhostRL · 09-01-2007, 11:46 AM

Any word on production?

SSGTBARCLAY · 09-01-2007, 04:14 PM

I am also interested in any after market upgrades. It's also good to see that Saturn of Tucson is a dealer.

Solution: sell both

YellowSky · 09-09-2007, 04:09 PM

make me a race pipe and bring it with you to FL!

Nova-Exarch · 09-25-2007, 04:37 AM

Bump...

Looking for an update on the downpipe.

I know we talked yesterday Eloy, but after reading this thread I did not realize you were thinking of two different options.

TOO MANY FREAKING TOYS!!!

Yar!

HotRedRoadster · 10-01-2007, 03:48 PM

so if someone gets the race pipe you can disable "cat efficiency" code from coming up in the ECU? I would go for it if it can be disabled

We can disable it right now, but thats not how I want to do things. I want to be able to get a cat that will out performan the stock one, but at the same time be just as efficient. For the race downpipe (no cat) we can disable the CEL (cat efficiency) code.
