Use band clamps as opposed to the clamps supplied with the system. I purchased mine at a parts store for $10 each. I also used exhaust system acoustic sealant around the pipes at each joint. I've had no leaks for the 1+ years I've had it.
The pipe that goes into the rear muffler (the one that goes over the rear axle) needs to be shortened slightly to allow the rear muffler to sit back further under the rear of the car so that the tail pipe does not stick out too far from the rear skirt.
The nuts on thr turbo need to be examined and tightened at least once per month for the first few months, then re-checked at every oil change (5K miles). I use a combo of wrench (one normal length and one longer length) to get at the two lower nuts, and a 1/4" drive ratchet (spinner) with knuckle and socket to get at the top-most nut, all of these tools in 13mm.
Performance is a major improvement, and paves the path for more uogrades (ECU, air delivery, etc.).
One thing to note: if your car has 2 O2 sensors, you will have to relocate the 2nd one further downstream since your cat will be moved from being under the engine (integrated within the dp) to being under the chassis (there's already brackets there for this). You will also have to have a "bung" welded to the intermediate (long) pipe to be able to install the 2nd O2 sensor. This will require the cutting and splicing of extra wire to lengthen the existing O2 sensor wiring. It sounds complicated, but it really is simple. Having the bung drilled and welded on is bet left to a muffler shop (charged me $20, and the bung was $7).
