So, I've been bored and fed up with my Neuspeed catback for a couple of reasons.. mainly I'm bored of the sound, but also the thing is just a piece of crap.. when 034 was done with the work this week I had them just throw the Neuspeed system out.. which brings us to the question: what did 034 do for you?? Over the past couple of weeks, I picked up a set of Fast Intentions 2.5" downpipes for a B6 S4 (with HFC's) and a MotorKlasse 2.5" catback exhaust (also for a B6 S4) made out of titanium. Going into it, we knew that we'd have to change some flanges and add about a foot of piping between the downpipes and catback, but other than that.. things should have gone smoothly. What we learned: The flanges at the exhaust manifold/hot side of the downpipe DO need to be changed, the O2 sensors are in different places, you DO need to fab up that 1-2 foot section between DP's and catback, but other than that: it all fits.. Moral of the story: if you have a 3.2 and want downpipes, go find a good deal on some S4 downpipes in the classifieds and have them modified (much cheaper than getting custom ones made). I had the work done at 034 Motorsport and got baseline/after dyno's BUT it was 60 degrees the day we did the baseline, and 100 degrees when we did the after dyno.. So, I will be going back once it cools off and will post the dyno's when that happens.. only looking to see a few HP, so no point in running heat-soaked runs..

I'm going to be washing the car today, taking more pics/vids .. update later today or tomorrow

What made this project a complete pain in the ass for a couple of days:


^That's one of the cat's that were in the F.I. downpipes I bought.. damage is on the engine side of the cat, and there were some varying opinions on how damage like that occurs.. It set us back a day in the process, but luckily 034 stocks high flow cat's identical to the ones F.I. uses, and the downpipes seller has agreed to reimburse me for some of the $$ .. I was driving around a crappy E36 with no 1st gear, so getting my B7 back has never felt better .. it sounds so pissed off now!
