So the setup is:

427 darton sleeved ls1
TSP Ported Fast 95/95 intake tb setup
TSP 1-7/8" Headers
TSP Catted Y

Motor dyno'd 540 at the wheels with 1-3/4 pacesetters and a 90/90 setup so I'm expecting a bit more.

I still need a catback and whatever to put before the TB (lid?)

Suggestions? Car is a street car only. Do not want rasp or excessively loud (no drone), but don't want to choke the free flowing setup.

Thanks,
Daniel

just buy wahtever catback you like, that sounds best to you, and slap a cutout or two on there. buy a 100mm lid or whatever the beggiest is and a 100mm or wahtever MAF or go speed density. that should set you up right.

I'll be speed density so MAF isn't an issue. I've been turbo for a while so going back to N/A is almost like a new world to me. Just looking for some specific suggestions/feedback.

Hooker cat back gets my vote. No rasp, one of the best flowing, great price.

Seems like people say corsa or magnaflow? Anyone else? Am I making a mistake by going with the catted y?

If you dont have a smog shop that's just gonna "pass" you on emisions, you're gonna want to keep those cats.

if you were not in cali i would say a flowmaster 1 chamber right off the y that would sound mean as hell

I'm going for no drone in the cabin. street car only. Thinking corsa?

Magnaflow has no drone on my LT no catted Cammed car

Mufflex 4" w/ Spintech w/ dual 3" outlets to the bumper here. 760 rwhp through the exhaust and absolutely no drone. It only picks up 10 more hp + 15 tq with the dual cutouts open.

I hear people complain about rasp on magnaflow setups. I would go with hooker or 1 chamber flowmaster after the y.

Sweet, I have looked at those setups too. Some have said that the spintechs were restrictive, but evidently it's not too bad!

2001WS6Vert

That' what I had heard too. I put the dual cutouts on and didn't really gain much, I was thinking maybe 40 + or more.

mufflex sounds good. How do they run price wise? Any recommended vendors to get it through?

Bought the mufflex 4" to magnaflow setup and a FTP 104mm lid. Am I going to need to replace the merge on my incoming TSP catted Y to be 4" out to not choke down my system?
