Well, all I finally got the SFR HKS 2.5 inch exhaust system (after from persuasion from sharif to go that route after waiting month after month for the HKS hi power.) I started installing today and was very disapointed to see that the piping did not fit around the driver side canal in the middle of the body, the whole piping wanted to veer outwards. We ended up having to pop the weld on that section of piping and weld some extension piping to get it to fit. After all of that was fixed, I was disapointed again to see that part of the passenger side piping was rubbing against the underside of the car, so monday we will have to do some work to get it away to keep it from pranging against the body. Those were the only two fitment issues. I was also unaware that the mufflers would be angled, so that kind of surprised me, but Its my fault, I should have done some research before I said "yes". I will post some pics and sound clips after the install on monday night or tuesday morning. This is also being bolted up to crawford high flow cats, so it should affect the sound quite abit.
