Does anyone have any experience with the glasspack resonators from http://www.roadraceengineering.com on a boosted car? I'm piecing together my 3" exhaust, and would like to know what kind of change in sound these are going to give.
Thanks

 

Yeah I'd like to know as well. I just sold my viren 3" SS to my brother for his 3" turbo back, and now i can't find another one

 

I was looking through the archives and someone said that they produce a louder sound, but that dosen't even begin to make sense. Anyone else care to share?

 

I used a 2.5" one 18" long on a custom exhaust for a friend. It cut the sound level down alot. It got rid of that high pitched buzzy sound, and gave the exhaust a deeper mellower sound. I welded the cat shields onto it so it looked like a stock cat to pass visual. It didnt seem to kill any horsepower, but we never made it to the dyno so i cannot confirm.

 

if you wnat 2.5inch i have plenty of them just no 3" ones

 

I used a 3" walker bullet race muffler from summit as a resonator. Works well. $36 http://store.summitracing.com/partdetail.asp?part=2383

combined with the 3" welded race muffler its a nice deep sound without being too loud or expensive http://store.summitracing.com/partdetail.asp?part=28912 Note the muffler pictured isn't the welded race muffler though.
