I've had my Greddy evo II exhaust now for a while and have had the same problem but don't know why I've never asked the question. Well here it is, I don't know if any of you greddy owners have the same problem but it seems like my exhaust piping is hitting the undercarriage of the car, does anyone have the same issues? I have original greddy pipes, solution/s?.

Thanks

 

put few spacer under undercarriage of the Z.

 

I mean put few spacer to raise up the undercarriage..so it won't hit pipe anymore

 

what kind of spacers did you use, or do you have the same problem?

 

yes i had same problem and I used 2 bolt spacer each side to raise up the undercarriage.

 

what bolt spacers and where exactly did you put them? thanks... I wonder f Greddy knows the problem.

The problem can most likely be remedied by loosening all the bolts on the exhaust and working your way from the front to the rear of the car. Most important thing is to know EXACTLY where the exhaust is hitting. You need to know this, so as you work your way towards the back tightening up the bolts, you keep the exhaust as far away from that area(s) as you work.

If you still cannot get it to keep from hitting and you are hitting on the cross member under the resonators, just get a set of large 1/8'-1/4" thick washers and space that piece down.

I don't beleive this is an issue with the catback itself. More of an install issue and possibly mixing the catback with aftermarket testpipes and/or headers.
