Wow that looks WAY too low. Try loosening all the bolts and retightening them with something holding the exhaust up, might help. I have Megan V2's as well (on the HKS knock off) and doesn't hang anywhere near that low. I'll check again tonight to make sure, but I really doubt it's that bad.

And I have some rasp. It's a cheap test pipe, so don't expect too much out of it. It is better than unresonated though that's for sure.

If you want to get rid of rasp, get some used Sebring Tuning test pipes, FI test pipes, or the ART pipes.

There was no difference in clearance after I replaced my stock cats for Fast Intentions resonated test pipes.

If I recall, the bracket is just there to support the weight of the stock cats, which are very heavy. All test pipes should be relatively light, especially compared to the stock cats (therefore making the function of the bracket not as important).

As mentioned, it's probably the design that is making you have clearance issues with the ground.

I swapped out my Strup test pipes with these to eliminate the major rasp i was getting with my exhaust set up ( 2k - 4.5k). With the megans i only get some rasp between 2.5k and 3. It def also helped in in cabin drone I was getting also.

yea I havent really got to drive around with my test pipes cause

A. I saw my intake was broken during installation of Test Pipes so I have a new one coming so I cant drive the car till my New Z-tube comes

B. My Y pipe is sitting super low.

My plan is get Z-tube on hopefully comes today or tomorrow. Drive down to Paladin (Shop I use) have them figure out whats up with my exhaust. Possibly have them switch out my Megan Test pipes as well for stock cats and get different brand Test Pipes.

Shop said its most likely the Test pipes I purchased have a bad flex pipe or just bad fitment in general.. Thus having them bend really easy causing my exhaust to sag.

They said I NEED new test pipes.. Not sure which route im going from here.
Either.

A. Stock cats and New Catback Exhaust
B. ART Pipes and keep stock exhaust
C. HFC and keep stock exhaust..
D. Test Pipes and keep stock exhaust

Yes I know as I stated post above you the flex part of my Test pipes seem to be broken causing rest of my exhaust to Sag. Getting rid of them and moving onto something better.

I had the same test pipes and a Megan y pipe. Mine sagged the same way. I got rid of the y pipe and test pipes. I now have a full motordyne setup including the art pipes v2 and everything fit perfect.. Save your $ and get the good stuff. You won't regret it..

I have the megan v2 test pipes with my nismo exhaust. And my y-pipe was scraping the flex part which will make it leak.

So I cut off the flex part and welded in a pipe. Made the y-pipe lighter and I can scrape all I want lol




Oh and by the way, did you get the Check engine light when you installed the pipes? If so, how did you fix the issue.
