Switch from Revo to GIAC

thanks WhAts stock downpipe and exhaust size ?

They wouldn’t recommend but I bet you could get a nice set of downpipes made

not sure about after cat, i think it’s approx 2 1/2 or metric equivalent, but stock downs are 60MM and they’re definitely more restrictive. I’m going to run stock this weekend since we finally have some decent weather and then I’ll be upgrading as well. Wanted to go stage 1 first and see what the difference is with each phase but his car’s performance makes jumping right to stage 2 awfully tempting.

I wouldn’t bother with stage 2.

Stock it’s a mid to low 11s car in good DA and will trap 122-124 mph. That’s pretty amazing on 93 with a 4400 lb monster.

Tuned is $2500 or so and should comfortably run high 10s @ 130 mph.

Beyond there you’re making your exhaust stink or your car is getting retarded loud. You didn’t pay $100,000 to for that.

Personally I think my next car is going to be eerily quiet so maybe I’m not the one to ask but there’s something to be said about an excellent sounding car that isn’t obnoxiously/embarrassingly loud.

Was my thought, I was more in the camp that the 5k even 2k price tag is steep. But pay to play and it is a 100k+ car. When they reach realistic levels I’d consider one but same headroom issue as saki, a little better space then a r8 tho :-p

Damn that’s quick for stock!! Congrats, thats fast stock m5s he’ll even faster than e63 4matic right?

WOW! That is impressive… Very nice 60ft time… Given the 7.132 1/8th I thought you’d land closer to 11.0x Stock tune most limit the turbos up top unless something else happened? Crazy that such a big car runs so well stock… Can’t wait to see your progression on it… Can’t see the whole slip, what was the DA?

Here is a better view I hope-

da on the first was about 1300 and 1500 on the second, not sure what happened on the first pass on the top end, car had a little bit of a funky shift in 2-3 so maybe that did it. If I could have merged the 60ft from pass 1 and the Mph from 2 i probably could have seen an 11.1 maybe better.
