Has anyone tried cutouts on these cars? I was thinking of fabricating a cutout valve just after the expansion chamber below the downpipe.

My only concern really is how it wil sound. i would make it so when i was driving on the road, i could have it closed, but when i was out at the track or whatnot, i could open it. has anyone tried this and knows how it will sound?

 

I have driven with just the DP and its figgin loud lol and i like loud cars but it was a little over the top.... some one makes one that if boost opperated thats pretty cool so it oppens up at high boost

 

oo. any idea the manufacturer?

and did it sound ricey or what

 

I dont think it sounds ricy Audis have a distinctly different sound when up corked but it can get annoying after a while

 

Ya, thats y id make it so i could essentially turn it on and off. for show or racing. then just going to school or whatnot, normal


OMFG my friend unbolted the cats and mufflers from his headers on his Camaro, and its EFFING BAD A$$ it sounds like a full blown dragster. its insain...

once i get my lazy butt around to doing it, ill poast a DIY and some sound clips

 

haha i love it. maybe it'll get annoying in like a year but right now i love how loud it is. and no i def. dont think it sounds like rice

 

are you running with just the downpipe?

 

same as badluck's setup. borla exhust and ecode test pipe

 

im not sure if cutouts would sound too good on an Audi. i think it might be a touch too loud/ricey sounding. i had a cutout on my LS1 and LT1 Trans-Am's and it did sound amazing. however i gained a little hp with it open; however i lost noticable torque. i would assume if you did this you would loose a little SOTP torque that you will notice. if you try though, let us know how it turns out.

 

taking off mufflers and such decreases back pressure, which in turn decreases low-end torqwue. but i would use this on the drags, at which, im never below 3k RPM and thats at the initial launch. it increases your top end power. you end up generally gaining mroe than you losse.
