Hey all, I posted a question for engine replacement over in that forum for my road Impreza, I figure since I've owned Imprezas for a little while now and I've used this forum quite a bit for info on my rallyx car prep, I should start posting.

Here's my rallycross car. It's gutted and has front and rear strut towers as well as a harness bar. I bought it from a club mate at the beginning of the year and only got to use it once so far! I made a fair few repairs and modifications/additions during the covid shutdown and raced it back in June.

Did pretty well for my first real rallycross but I broke the exhaust (again, apparently it had been re-welded multiple times). In between races I decided to just go ahead and replace the whole thing, it was a frankenexhaust with an aftermarket header, stock cat pipe, and a blown out muffler that didn't muffle any more. I decided to keep the header and just go 2.5" straight pipe right from head to tail. I don't have a welder (yet...), so I decided to get fitted pipe and used lap band clamps to fix the whole thing together. It actually worked really well, no leaks at any of the clamps which is great. It is obscenely loud though and I feel guilty for subjecting my neighbours to it whenever I fire it up .

I used these cheap strips of metal to hang it, they look flimsy but they're holding well, and it looks like the isolators are really stressed in that pic but that was while I was locating the assembly. I added 2 more hangers to lift it into place in the middle and relieve those rear isolators.

Anyway, I'll be racing it this weekend so it'll be interesting to see the performance difference with this exhaust versus the old 3" one with cats.

e: anyone know why my image links aren't imbedding?
