I have tried searching but i really couldn't find the answer i was looking for. I am looking for a downpipe to mate up with my catback but i have a few questions directed mainly to people who has this catback. what kind of downpipe are you using and how is the fitment. This catback uses the doughnut type flange to connect to the stock downpipe so i realize downpipes such as cobb and pde uses the stock design also. My main question is for people who has successfully connected the espelir catback to other downpipes such as helix and invidia which uses the flat flange design. Who has done this and what was fitment? Also would like to know about any exhaust leaks. Thanks for reading and sorry for the long post. I hope someone can understand what i am asking...lol

If you want to use a flat-flange downpipe you just need to have someone cut and weld a new flange on the catback.

 

I am aware of this proccess but this wasn't what I'm looking for. I was looking for people who has used the flat flange design with the doughtnut flange. Anyone?

 

i have that exhaust and hks(flatflange) downpipe i went to midas and bought a double doughnut gasket part number EN1493 works great no leaks

 

here is a link to what itlooks like remember if you use the gasket to use your stock spring bolts

thanks for the help and also the pic. I know a guy, who is a moderator at clubwrx running the espelir with the hks downpipe but he didn't do any modifying. he got it to bolt up and not leak. I am looking for other people who has done this

 

no problem...it seems like some have luck and some dont i didnt even try the flat gasket just went straight to the mdas one
