Downpipe differences

[Nikw91]

Well what's your budget and plans for modding? Any restrictions (like emissions related). I'd say you just go with what you can comfortably afford and if you really care about power, go catless. If it were me, I'd go TSP because I like PRL stuff.

No budget. Just cheap and don’t like wasting money lol

You should probably just keep it stock. Like TSP said the oem exhaust system is pretty good as is.
I personally don't see a need to mess with it in less your doing a turbo upgrade and turbo back exhaust system.
Canflex and tune is your best bang for buck

I have the TSP downpipe on order because my state has emissions testing. Even if the emissions fault code is blocked on the tune, the state test will bust me and I will be hanged from the neck until dead.

Did you mean turbo cat back exhaust?

Dp,FP and exhaust = turbo back

After more research. The 27WON maintains factory heat shield and has the cat is only 200 cell.

In theory, would the 27won 200 cell downpipe flow a lot more efficiently then the 300 and 400 cell downpipes?

27WON is the only company to post actual dyno/hp numbers. All other downpipe companies just say “more” power and faster spooling… which is kinda suspect.

Ok this is going to piss some people off but,

MAP advertises a GESI cat. They come with a cheap 200 cell cat and you WILL get a CEL.

I lost my shit on them and was told to f myself basically. You can pay them hundreds more and they will custom make you a GESI catted downpipe.

just by a TSP if you want a catted DP

if you want a straight pipe it will be louder and more power but you will get a CEL, unless you tune it out.

It’s kinda common knowledge that all downpipes will throw a code other than TSP.

No tune then go tsp…

Tuned, can go any downpipe.

Does tsp even alter the sound?

If you get an OTS tune from the normal vendors they come locked so what that means is you can’t disable your CEL from the DP

My bad, that’s weird. Every other car I’ve had with off the shelf tunes came with the sensor disabled so i wouldn’t throw a cel.

Whose tune are you using?

How is the sound/performance of the MAP downpipe otherwise?

Curious to know too.

The 200 cell count looks a lot freer

I’m running a @Jester04 tune now. I had a TSP tune when I first got my Hondata.

Downpipe did add sound. There is a video here on the site.
