  Good product, good fit, good sound - watch out for rattle
By on 1/2/2014
My brother and I did this install using a lift in my dad's garage. It took us about 11 hours. I could do it much faster now that I've done it once...it really was not that hard once you figured it out.

I do NOT recommend trying this without a lift. The headers are a very tight fit and difficult to maneuver in to place. We had to raise the engine up a few inches just to get it in place (another reason the lift came in handy). The bolts are difficult to reach and loosen. There are 8 on each side. 4 on top, 4 on bottom. The front 3 on top had to be loosened from above and the rest from below.

Did not have any problems fitting the headers to my manifold/engine and did not have any problems fitting the x-pipe to my magnaflow comp. catback exhaust. The sound is phenomenal with a Jon Lund ghost cam engine tune. The power has noticeably increased where it was needed most- in the higher gears. The car pulls harder from 60-80 and beyond. Although, since it is winter time I have not had a full opportunity to let it rip at higher speeds.

The only negatives i can say about this product is it doesn't come with clamps. The stock clamps just didn't fit it so I had to run to the store to buy different ones. Also, there is an annoying rattle where the headers or x-pipe (can't tell which yet) are either tapping against the body or the steering column. Many have reported they are forced to put a dent in the header near the steering column to avoid the rattle. I think my rattle may be coming from the bracket connecting the header and x-pipe on driver side. If so, it will be an easy fix.

If it is from the steering column I will have to shimmy up my engine by adding washers under the engine mount on both sides or I will have to remove the driver side header and put the dent in it. A quote from a local body shop was $500 to do this....so I'll do it myself when I get time and just deal with the rattle for now.

I gave the product 4 stars because the product itself is great- but to avoid rattle you may have to compensate the product some...and it should have come with brackets imho.
