what's he difference between mid-pipe(second-cat delete pipe) and SR pipe? - BMW 3-Series (E90 E92) Forum

kiddo · 09-29-2008, 02:32 AM

So I was on youtube just now and found a video of a 355i with bastuck quad and SR pipe which seems to be louder than the bastuck quad with second-cat delete pipe. Can someone clarify with for me and tell me the difference? Thanks

No differences. SR or mid pipes are just the same. Some are from eisenmann, others from Riss Racing, Borla ...

S/R pipes and midpipes are one and the same, Ken

when you coming in for some Riss downpipes?

How come they don't show any hp/tq ratings for midpipe changes? The length of the pipe of the midpipe is huge so making that 2.5" just like the downpipes would be a pretty big help for breathing better I thought.

go catless man...you'll have money for that since it's cheaper

i'll give you a ride in my car and that should seal the deal...they are really that awesome.

when u coming to visit?

does the catless version give you more gain than the catted one?Which one gives the turbo more pressure?

I will probably go down to Chicago the weekend of the 12th or the weekend of 21st. I will give you a hollar before I come down
