I currently have SPT catback and was looking at buying an ERZ downpipe from John in the near future. Do I still need Kartboy Extra Long Hangers if I go this route, or will I only have to cut the AC line to make this setup work? Also, has anyone had any issues mating the 2.5" SPT catback flange with the 3" downpipe (leaks, fitment, etc)?

^ this.

btw, i painted the can/tip flat black on my SRS this weekend and it came out pretty nice. i'll have to post a pic soon. while it will never change the fact that it is a fart can, it definitely makes it more stealth.

OR

just to add to this thread

I have the ERZ uppipe and downpipe on my 03 with the SRS catback

Installed everything myself. Only problem was the uppipe studs being to long, had to grind em down a bit

Been running this for two months now and have nothing but thumbs up. Car is loud and runs so much stronger from stock. Stage 2 opensource flashed with romraider.

I recommend this to anyone on a budget.

This is a newbie question, but since the thread is on the same topic practically, i didn't want to make a new thread.

I'm probably going to buy the SR*S Catback, and if i do, is it a necessity to also buy a new downpipe? Or what are the disadvantages to sticking to stock + the catback? Or is there no point in buying a catback without also buying a downpipe?

EDIT: Plus, since I live in CA, ill still pass smog with this thing right? I don't see why i wouldn't, so that's my guess.

Hopefully you guys understand what im getting at.

Thanks

it is not a necessity to get a downpipe. but what you will need is an adapter to run the catback. you can buy them for $35 shipped, it connects your 2.5" dp to the 3" midpipe of the catback. you will reuse your stock donut gasket with this adapter, here is a link: http://www.fredbeansparts.com/servle...pipe-to/Detail

passing smog is no problem since it is a catback, you arent doing anything to your cats, so it wont matter when it comes to the sniffer test.

btw, here is mine, i painted it with high temp paint. i get complements all the time on it and it really does look stealth.

bought my sr*s catback off same guy on ebay for my 2.5...220 shipped. love it. had it on for about 2 years now...had minor surface rust at first...but took some tinfoil and pepsi to the tip and it hasn't rusted since and shines like no other when it's clean...try it. lol little home remedy 4 ya. makes really fine scratches but barely noticeable. and now its rustproof for some reason. bad ass.

Sorry to bring an old thread back to life guys, I just installed the catback on the stock downpipe yesterday. Everything was right on except connecting the midpipe to the stock downpipe. different flanges i guess (I didnt know lol). I was wondering, will it be any easier once I get a 3' downpipe to mate with the catback?

Yeah it'll work since I believe the stock downpipe requires a tapered flange and srs uses a flat flange

I just installed my 193.95 no name exhaust and dp combo. Sounds great, no issues except I can't use my dif guard till I have it trimmed. Exhaust is exhaust unless you want a fancy flamed tip or a name welded to it

i wrote an essay about the "ebay exhaust and intakes" vs. "namebrand" for my writing121 class a couple terms ago.
dyno tested.. no BIG difference. there was a slight difference i think it had more to do with the intakes than anything.
