Im thinking of putting a cutout on my Z, my exhaust note is quiet for me, and believe one would help me out with a full bolt on car.. Im thinking 3" by the rear wheels... what does everyone think? I get no vibrations from my catback right now, but how bad would the noise in the cabin be??

 

and my car needs a driveshaft.. that was my next mod, with a DS Loop, which driveshaft would be best to buy and where? thanks guys appreciate the help!

 

I just installed dual 3" electric cutouts on my '97 Z28. It is already decently loud without the cutout, but with the cutouts open it is very loud and sounds great. Plus, you can just flip a switch and in about 4 seconds it goes back to nice and quiet. If you are running true duals like I am, just come straight off the header on each side into a dump with a QTP electric dump on each side. You'll love using it!

 

I hear of guys running an LS1 driveshaft on here. I guess it's made of aluminum instead of steel like ours on the LT1 are constructed.

 

An LS1 aluminum driveshaft is a nice upgrade indeed. You can get them for around $ 90 off ebay or in the parts for sale section of the forum.

 

Would aluminum be a good investment? I don't want it breaking on me lol, but ill give it a shot... anyone else care to chime in?

 

What's wrong with your current DS?

Many people that have a problem with DS vibration after going to higher numerical rear axle ratio (3.73/4:10) will swap in the 1LE or the LS1 aluminum DS to eliminate the vibration. Works fine, until you get up to 500HP or so, and then you are at risk with the stock aluminum units.

 

Hmmm nothing really just was told that should be my next mod or a Ds loop... what do you think about a cutout on my car... would I benefit?

 

It's all personal preference. If you like loud, you'll like the cutout. You can't really go wrong with one honestly. If you don't like the cabin noise during normal driving, just keep it closed till you're at the track or wanting it open.

Just before the rear tire is fine.

 

My flow catback sounds great, on just wondering if its hindering my performance at all.
