Get a couple of surface prep discs, and when you're done polish up the finished pipes, and pieces. especially around the welds on everything. They won't rust as fast. The poilshid surface on the muffler should stay that way for awhile, but the pipes WILL start to gather surface rust after awhile.

 

That's going to be a badass setup. I've been thinking about the cutouts too but they dont allow them at Infineon so I've just put them on the back burner.

 

How much did your kit cost you, and what size tubing is it?

Thanks.

 

I'm in it for about $850 now. The mandrel bends, straight, new muffler, x-pipe, cutout pipes electric cutouts, hangers and miscellaneous stuff. I might be using the 4" round mufflers another $110. Might need some more bends and still deciding on what tips to put on it or to use the big Corsa's I have. Stainless is expensive! They are 2.5"

 

What! No cutouts at a dragstrip! WTF is up with that?

 

WOW!!! How much just for the bends, straight, and the X-pipe?
Also who did you buy from?
Thanks.

 

Not sure why, but full exhaust only at the Weds night drags.

 

IHRA tracks require some sort of muffler, NHRA tracks are more anything goes. I cant stand IHRA tracks, there list of requirements is alot longer.

 

the Wed night thing is probably a city ordinance or something

 

So tell me about these DMH's, how well do they seal?
