you can compare parts number to see if it is the same part
but if youre talking about performance gains, not sure.
No I'm not looking for gains. I've got a poor man's type R in a 92 hatch with a greddy SP2 exhaust right now. I just want quiet. If an LS is more restrictive than a GSR I'm not going to go for it, but I've got a kit wanting to get rid of his LS muffler.
All I want is stock quiet sound without giving up TOO much flow. I'll take advice on a super quiet aftermarket muffler too of you've got it.
