Where can I buy performance exhaust without Pipe?
Time to upgrade my n54 135i, looking for n55 midpipe and performance exhaust without the Ypipe. Anyone know where I can get these at a reasonable price new?
Can the exhaust come without Y pipe or is it always together when new? Edit: title should say Y pipe, on mobile autocorrect got me

I've seen it as always together. I didn't even know that was part of it until I tried to sell my PE exhaust, just the rear section. I'd offer to sell it but I switched back to it.

alternatively, a downpipe with secondary cat delete and stock muffler will perform better and drone less. |

The plan is VRSF catless down pipes to N55 mids and the performance axleback. I like to keep my stock parts in storage so I can always go back

Tried it and hated the smell and sound. I went back to N54 mids with my DP and PE.

What was wrong with the sound? I figured it would sound pretty good eliminating secondary cat with a resonator in place from the n55 midpipe. Also, what did you do with your y pipe?

I had my indy check and everything was installed properly, I do not have a y-pipe (resonator delete). Bottom line, when you're completely catless, there will be a smell, it just depends on how much you can stomach. Sound-wise there was an awful drone around the 1400-1700 range which unlike the autos I can control somewhat, but I mainly do city driving so it still wasn't pleasant. Also, the exhaust note became similar to an 1990 diesel truck.
Once I put back on my N54 about 95% of the smell is gone. I might do the res delete to gain some crackle and pop. Quote:

with the windows up, you probably wont smell anything. when stopped at a light with the windows down or doing WOT pulls you will probably catch a whiff of cats. |
