Hey guys just wanted to state that this is my first car I will be trying to build so forgive the lack of knowledge. Just here trying to get some helpful advice on building my em2! Atm as my car sits rn is bone stock, my exhaust rusted out and lost it in the road was planning on swapping to a catback anyways but this incident kinda gives me a reason to start it now lol. I've been looking between tsudo yonaka and magnaflow any thoughts??? (Advice from experience?) Also need a new header as the stock 4-1 is rusted and done was considering megan headers also any thoughts? Would love links and thoughts and reasons to why which would be the best route! Also not trying to cheap out but also going to try to keep it budget

There is a whole section on this forum with bolt on performance info. Search around a bit.

Personally I had DC sport 4-2-1 (cat delete) headers and a Magnaflow cat back. Hated every second of it, it was way too loud for my taste and sounded ricey.

DC sports 4-1 (keep cat, it meows) sounds better.
wait for the discounts, it's almost time for the THmotorsports discounts in November (that's when i got mine)

Ex headers are about as good as you can get for headers. Aftermarket might offer a little better flow. Add a high flow cat and HKS axle back. Makes a very nice sound. I have a video I can post in a min.

Sounds dope homie chance you could hmu with links to buy??
Also my oem header is done for I know aftermarket wont much different but I'm also going for looks as well as performance

Use the Google to find the cheapest price. I bought it used.

Yes aftermarket would be best then.

Would I be able to get a catback and just bolt the hks axle back to the catback later down the road??

ProjectEm2

Like if I order a magnaflow catback now but buy the hks axle back let's say a few weeks or months later if I take off the exhaust tip from catback or to any exhaust is what I mean when I say that I guess lol

As long as the magnaflow has an axle back section that can unbolt from the rest of it which from looking at pictures looks like it does.

The Magnaflow has a nice sound too. Opening up the exhaust from the cat back really doesn't do much as far as adding power you are just changing the sound.

ProjectEm2

Yeah the power would come from removing the cat if I'm correct which I've been considering if I find a header that would bolt from the block to catback any suggestions?

On a performance engine yes but on the D17 it will not add enough to put up with the noise and pollution. The only way to make quick power is to put in a stage 1 cam. At that point the engine would benefit from the headers.

Use the Google. eBay has cheap headers.

So keep the cat ?

GolNat

I would.

Or get a high flow cat but for the price I would just keep the OEM one.

BrotatoChip

Mine did not. There were three sections of pipe, the first bolted directly to the downpipe after the cat. The other two slipped into each other and then a pipe clamp was used to hold them together.

Good to know! OP would have to get a flange welded onto the Magnaflow end or have the HKS flange cut off so it could be clamped to fit. Not worth the trouble IMO.
