I love everything about the 991 turbo except the exhaust note.... I think perfection is the sound of a jcr race pipe on a 991gt variant. Anyhow, is there any exhaust out there that makes the turbo sound more "exotic"? I figure the closest I'm going to get is a full inconel catless kline system?

I think you named it! Full Kline inconel with no cats is probably the best your going to get. And honestly I think it sounds great with that setup, waiting on my stainless version to show up!

I have the full inconel kline with headers, 200 cell cats and exhaust, though not catless, it sounds amazing on the throttle, but I'm sure it would sound even better if it were catless

Exotic note is very individual. You really need to listen to the exhaust in person to be sure it is what you want. For me, the Kline Inconel with 100cell cats is perfect. 80mph Cruise is quiet. Part throttle at 80 is a low tone, idle is much improved, wot is GREAT.

This is exactly what I'm looking at - just a bit more presence. How much added burbling and popping is there in the various modes, as it's the one thing I'm not looking for? Thanks, Doug

do you get a CEL with 100 cell cats?

onfireTTS

No Cel or pending Cel. I did install the 1” spacer before the secondary 02 sensors. Works perfectly.

good to know, thanks

Hey there!

Let us know if you're possibly interested in going our route! Here are a couple of clips, first our GMG WC Exhaust with a stage 2 GIAC Tune, and the second just the exhaust on a fly by:

Just installed Kline 304 w/100 cell cats. Sounds amazing. This weekend I’m going to flash Cobb Stage 2.

You get more turbine whine in all modes as it spoils quicker. Burbles are only present in Sport Mode. None in Comfort or Sport Plus. Worth doing for the idle enhancement.

i would like some burbles in normal mode. I love sport mode but there are times I don’t want the long gearshifts. Still, very pleased with the Kline product.

Am I correct in assuming the Kline SS and Kline Iconel systems sound the same? The only difference is the weight and the cost? I love the sound of the Europipe with 100cell cats. Better than stock but still a Turbo flat 6 character. I however would never characterize any 991 TTS exhaust note as "exotic." People definitely don't buy these cars for the sound.

Elliott991TS

it's my understanding from Sam that the Kline Inconel sounds a little higher pitched compared to the SS, he has some videos that demonstrate that

Inconel has thinner walls and therefore a higher pitch
