Paired with my Roush axlebacks
Since I am the first to review this product, I feel the responsibility to be thorough...so here we go:
The fit was easy and perfect for my 2013 GT. I tried to do the install myself, but two of the bolt clamps were impossible to remove with the large ratchet/crescent wrenches I own (the bolts are both vertical, with the head end farthest away from the ground). Given the limited space available to remove the clamps, I decided to take it a local mechanic. He said it took him less than an hour total (don't let a mechanic tell you otherwise). Absolutely no welding was required; this is a true bolt-on swap of the stock H-pipe.
I already have the Roush Axleback Exhaust installed. I noticed the idle sound is slightly softer, but the sound at acceleration sounds much better. The X-pipe made the start-up roar much louder, and faster. Already received compliments on the sound, and the very very light drone of the Roush axlebacks has been completely removed. I was happy to that you can go 100mph @ ~2,100 RPM (steady, without accelerating) and the exhaust doesn't make a sound at all. The instant you press the pedal, you get the roar, regardless of your speed.
I did not do a before/after DYNO, but I can honestly say the acceleration is MUCH smoother after installing the X-pipe. With the stock H-pipe, the car seemed to "gulp" upon a heavy press of the gas pedal, but that "gulp" has been almost completely removed. I don't know how else to say it, but the car just seems to be "breathing" easier, and it shows in the acceleration more than anything.
- The install is very easy; read the instructions given on the product page (but keep in mind, there are two vertical bolts which are very difficult to unbolt)
- No welding is required
- Idle is slightly quieter, but the improved roar is noticeable
- Night and day difference for full throttle acceleration
