Im not sure about the srs. im running a thermal r&d cat back with a megan downpipe. i had modify my thermal r&d to mate up to the down pipe. make sure the diameter and flanges are the same where the catback and downpipe meet up

I've been looking into this as well. I have the SRS catback already, and I am looking for a downpipe too. I was hoping someone can chime in as to if the Megan Racing or Punishment downpipe both bolt up properly without having to cut, and re-weld the flanges.

I have the srs cat back with the punishment racing downpipe, you have to make a little piece to connect one to the other

@Luisito- Is this because the two fall short of connecting, or is the flanges not aligned?

Megan racing 3inch downpipe on extremepsi here's a link clearly says eliminates
Cat I'm sure you could've found this with a bit of research.

i did do some searching but the people that make the down pipes dont say what exhaust it will mate up to. I was looking into advice of people who already have there set up done and what they used. thanks everyone for the imput so far keep it coming.

From the info I gathered the Megan sometimes bolts up sometimes it needs cut.

any body running a 1g with srs cat back. what down pipe are u running. how well did they match up?

My srs bolted right up to my Megan dp no problem. But thats 2g..

@ paintballa55 did u need a test pipe or did the down pipe meet up right at the cat back

No test pipe required. Bolted up perfect

well damn things seem very hit or miss with the megan down pipe. thats the combo i want to run becouse they "work so well with each other".

It works pretty well. I couldn't have been happier with it. I also cut the resonator it comes with out.

This is on a 2g, I can't speak for 1g.

ok did a lot or reading and it looks like the megan down pipe fits perfect for FWD turbos but there seems to be alot of problems with gsx's. this all being mainly 2g's i was very few 1gs running this setup. we have a different set up. and speaking i have a 92 tsi awd who knows how things will fit up. any imput from the fellow 1g drivers running srs catback chime in.

Ok on my fwd the Megan cat delete bolts up perfect to my eBay catback. But on my buddy's gsx he had a thermal catback and I ordered him a cat delete off eBay. It is exactly like the Megan cat delete for a gsx. We had to cut about 2 inches if I remember correctly and reweld the pipe together with the section removed. After that it bolted to his thermal perfect. Both are also 2g.
