Just got my Obx long tubes and catted y installed. Here some pics:

 

Some more

 

Here's the dyno

 

The catback I have on there now is SLP LM2, overall the car sounds great. Sounds maybe a little louder than stock at idle, but wot sounds incredible. Ground clearance is horrible though! Might have to do some adjusting. Seems like I scrape everything!! I am lowered on Strano spring though. Anyways, I'm pretty happy.

 

Your ground clearance is what it is. As long as the pipe on the driver side is as close to the car as possible without rubbing it thats all you can do. All y pipes should have the section where it hits the car flattened out.

 

Looks good man.

 

How was the install? Everything fit OK? I'm replacing some old SLP headers and Y-pipe with these in the next couple of weeks. The SLP's were horrible for ground clearance, but these look like they'll be better.

 

Well they were installed at F-Body Central in Baltimore, Md. They said the install went well. I only have a few inches of ground clearance, so I try to avoid all speed bumps and steep driveways. I'm gonna put some hangers on this weekend to tuck it up a little bit more. The y pipe is drooping down for some reason even though everything is tight, but I should get much better clearance when I put the hangers on.

 

Yeah that ground clearance isn't great. I do wish everyone used flanges though. All those slip fit headers these days are such a hassle to work around once they are installed.
