This is great advice... For every one person I've come across that ventured into the 'custom' territory when trying to get around an exhaust issue and had success I've seen at least 5 others that end up with this same sentiment. If you were venturing into uncharted territory with a one-off build then of course there always has to be a first, but with an issue like this thats been tackled countless times, you'll probably wind up saving yourself a lot of hassle and possibly even a little money by buying off the shelf. The materials alone to start fabing up your own system that won't rust/rattle within a month's time can add up quickly. Good luck and keep us posted with what you end up doing.

 

We have two straight pipe options:

1) Cat bypass pipes (test pipes) with muffler bypass pipes

2) 100 cell cats with muffler bypass pipes

Pricing for 6speed members is as follows:

Cat bypass pipes (test pipes) with muffler bypass pipes - $995.00
100 cell cats w/ muffler bypass pipes - $1,550.00

Both packages include the V-flange clamp, which is required to install...

 

imolafem: any solution. yet?

 

yeah or are you going to continue blowing air out of a tiny straw

hey if you want to hold off, on this forum is a thread on how to drill out the factory exhaust, thereby bypassing the mufflers. it sounds much better and probably flows enough to give you some of the performance back. good free solution for now.

 

I have some for sale. Check my signature for the link.

 

Amanda, this is a great deal and TX has the same umw flash like you do, well, except yours is for 6000 ft.

 

3-Only for all 996 Models including Turbo (Does not work for 987,Cayman or 997) . You can install some O2 sensor adapters that modify the 2nd O2 sensor reading and fixes the issue most of the times. We have these available if you encounter the Check Engine Light problem just let us know we can provide you with the bungs for a minimal charge.

Has anybody else tried this an pics ??, I need a solution too and this might be the smartest without an expensive reprogram !!

 

How soon does the CEL come on if the 2nd o2's are present; once I reset the ecu via scanner?

 

Without the O2 sensor simulator mine is 7-10 days after a battery disconnection & reset, its very annoying, even with 4 cars to drive, 6 months for a low cost sensor adaptor seems fine to me

Just ordered them

 

I have a set of FABSPEED "Test" Cat Bypass and Muffler Bypass Pipes if you want them. Lightly used and a lot cheaper than new. They are in the For Sale section.

Any other thoughts on this; I will post when mine are fitted

 

Richard, did the Maxspeded simulators help?

 

I just went the Durametric route for now =) Maybe one day I'll get a different exhaust.

 

I run the UMW K24 flash, and paired with Stef's EP GEN2 exhaust, it's the sweetest sound in the world, both WOT and off throttle gurgle. The EP exhaust with Kevin's WGA kit reduced lag by about 70%. Very happy with the extra ~100 HP.
