^^^ Hahaha. In the 80s I had very little money as a starving college student with two crap jobs.

Every cheap car I had - the first mod was the hacksaw treatment - off went the muffler.

Had a Saab Sonnett that was horrifically loud, not in a good way. After one job I'd drive home through NW Portland at 2-3am almost every night blasting away up every street.

This guy one night was waiting for me and ran out in front of my car in his pajamas waving his arms. I thought damn, I worked a 12 hour shift and now I am probably going to get my *** kicked by this big 40-something dude.

Instead, he was super polite and told me every night I was waking up his whole family and please, please could I go another route. I complied. If he was a jerk I would have targeted him for worse noise.

So Savier St got the treatment for the next fews months instead. Everytime I see some kid driving a loud fartcan car I don't mind at all, that would be hypocritical.

 

Here is the best solution for sound (in my opinion) but you have to be a bold person.
1) 200-cell Velocity AP downpipes, but with the stock muffler on the V8, it's doesn't sound very refined.
2) Velocity AP Valve-tronic Exhaust. Sounds really good and refined in touring mode (Valve-closed) and amazing aggressive and beautifully loud when open. I get tons of compliments on the sound when I am rallying.
3) If you hate the loud start-up (which i do 80% of the time), add a custom vacuum pump to the exhaust and wire it to a switch or the OEM muffler button (which I did to keep everything feeling stock). This allows me to start the car in quiet-mode.

 

Define option 1) not very refined ....
I have an SVR with VelocityAP 200 cell cats on the way .....
Thanks!

 

The 200 cell cats without a different muffler, make the car sound far to raspy. Makes it sound more like the granddaddy of all ricers rather than a refined exotic.

 

Remember the V6 & V8 are going to sound very different though.

 

exactly Stuart...v6 prob does sound raspy. V8 outside of cold start sounds great with valves open.

I'm going to add the Valvetronic race exhaust soon as I like it really loud.

 

Even the V8 with the 200 cell down pipes sounds a bit raw and raspy to me. The Valvetronic acoustics resolve that issue.

 

Anyone else have an SVR with the 200 cell down pipes ?

 

Agreed. I hated the sound of the V8 with only the 200-cell down pipes. I really love the volume increase, but I hated the sound quality. Raspy & unpredictable sound quality. It made me want to stay in low RPM and avoid WOT, whereas the OEM setup was perfect and made you want to get on the gas, but just too quiet. The 200 cell + valvetronic made everything awesome again. Note: I have the tune installed which ups the volume as well.

This is my personal opinion obviously, some may like a loud raspy V8 sound.

 

Hoping the SVR's stock exhaust combined with the 200 cell cats is less raspy then what the R seems to be exhibiting ...
I remember listening to the SVR and the R side by side and the SVR was deeper.

 

Yes, no, maybe from the gallery?

 

I guess you will find out soon, and report back.

 

Stuart,
Any chance you'll be offering a discount or group deal on the V8 Valvetronic muffler anytime in the near future.

 

Neighbours.. .. whats that ? I live in one of the most crowded countries in the world, in one of the last places with almost nobody around... Could start a Saturnus V at 6Am and would ony give some squirlls a hartattack..

 

I'm in

 

I don't see why we couldn't run another group buy. But last I checked you had a V6

 

I've had the valvetronic on my R for a couple months now, couldn't be happier. Enhances the cars sound, and makes it more audible inside the car - I can hear it in both modes with the windows up or down - could barely hear the stock exhaust even in loud mode with windows open.

I imagine the OP would be best served by trying the valvetronic first, may really accomplish what he is after.

 

Only part I'm missing for a quad pipe conversion is the muffler. I understand from someone who has done this conversion that it offers a deeper note.

 

I'm in if you run it again.

 

I’m in!
