This might be an odd question -- but are there any recommendations for 996TT exhausts that are NOT much louder than stock? I'm interested more in possible performance gains, but I'm not looking to make the car much louder (I especially don't want to have problems with the sound limitations at some tracks). Any ideas?

 

Speedtech 2.5 cross flow. I have the 3.0 and it can be loud, but really not that bad. I can only imagine the 2.5 is much quieter.

Unfortunately I don't think any of them will be at the 93 db limitation of Laguna. Since they only measure it on that one section, and from a distance, I'll bet the speedtech will be close. I used to track a subaru sti there with a catless setup and never had a problem.

 

You've got to hear my Europipe Stage 1. This would be the exact exhaust to meet your goals. Its got a much lower tone than stock and Its only slightly louder under normal driving and lets out a nice whale when you get on the throttle at high rpm. You can hear the turbos spooling which is cool too. As far as performance, it is noticalbe from my "seat of the pants" feel. Turbo lag seems to be all but gone and the turbos spool sooner in the RPM range so the biggest power gain feels like its in the lower end. I sure do love it. I still haven't taken it back to Sharkwerks yet either for an updated tune which they said they would do whenever I got an exhaust so I guess things can still get better.

I was going to go to Santana Row for cars and coffee today but the weather seems to be doing away with that idea. Maybe next weekend and you can hear it then.

 

Sounds good -- I'll look forward to hearing it! Since I have to go out that way anyway, I'll be swinging by SR shortly. Catch up with you next time.

*** Edited: Just another quick thought -- if it's much louder at WOT, that might still be a problem for me. As you can imagine, sound meters at the track are usually located where you'd be at WOT.

 

I had the secondaries removed and the tip "poke-through" mod. Its louder than stock but not completely crazy.

 

Hey,I love my Milltek system for those reasons!!

 

Does the poke through mod improve performance? I thought that was really just for sound.

 

cut your oem exhaust, take out cats,reweld new cats on and done

 

It helps,,anything you do to let more exhaust out and to get it out faster will help the performance of the stock restrictive system..

 

Thanks. Didn't think of that. So it's the cats that are more restrictive than the exhaust? Would I go to fewer cells?

 

Also,you can punch out completely the first set of cats on each side.You have 2 sets of cats on each side....

 

I've got poke through stock right now and can really feel the performance hit over my Miltek and Switzer. Gutting the cats would help. For the money might be with looking at PBK.

My poke through and Miltek passed at Laguna. Should have kept that Miltek...

 

My previous exhaust is that , no secondary cats and 3" cut out on the internal pipe- sounds good- very good. Let me know if you are interested. I'm not going back to it- i love my current exhaust. Also eugene, it depends on what rpm you are at turn 6 i believe it is at Laguna. I do NOT pass with a full stock exhaust...fwiw. But if Daren can pass with X pipe of a tubie, i'll find away to pass with mine

 

We make them per order per client. Thus, we can build one to specs without complaints in most cases... We make the mufflers from scratch as well and choose various material combinations in building it depending on the goal.
here's a sample:
