Any experience with the 335i-style insidePerformance exhaust?

[1series_rulez]

Has anyone any experience with the 335i style exhaust from insidePerformance (Germany)? They have one tailpipe left - one right - like the 3 series 335i / 335d

A friend has the quad m-style exhaust from them and is satisfied.. but this 335i-style seems to be new

Anyone having it on an 135i N55? I am interested in some soundvideos and some more pictures..(if possible on a blue 135i - they only have this white 1series in their shop)

looks a bit odd looking IMO. The quad looks better

The exhaust tip style won't change anything on the sound imho, why would it. So you can tell them how loud you want it. I have mine from them (quad) and am VERY happy with fitting and sound. It's a bit loud at cold startup but every other time the sound is so awesome that it more than makes up for it.....

I like this 335i look. But.... 1,700 euros ($2,200 USd) for an axle back(?)exhaust and valence is a bit steep - I think.


This is the same company that intitally had tourble with their 135i exhausts. They were using too small(dia) exhaust pipes and it actualy reduced the 135i's power output. I remember a thread about this - maybe two years ago. The 1addict ended up having them put back on his OE exhaust after a week. I seem to recall that was the four pipe M looking exhaust.

The thing that puts me of InsidePerformance exhausts is in the 3+ years I've been on the forum, I've never seen a photo of the layout of the exhausts. Apparently they won't release it because they're worried other companies will copy their design but I have a feeling it's very restrictive.

This quad design looks odd.
There are some good brands which I will use: Hartge, AC Schnitzer or Eisenmann.

You get cosmetic looks and performance gain.

IMO I doubt you get any performance gain with a quad axle back. They are all for looks even for those brands

+ 1

All quads will compromise some performance. Some look really bad. IMHO, the newly designed eisenmann quad looks very compromising. The most free-flowing exhausts with the least bends are the best, performance wise. Berk, CPE, AA etc.

Hi,

thank you for your support..

I went to inside (via email) with these arguments from you all..

They sent me links to two dyno diagramms from this new exhaust.. can you help me? What does it mean exactly? I am not firm with reading dyno sheets.. and my German is not very good
