Please list what exhaust you have, and your experience with it.

Exhaust related question - is the stock exhaust a source of restriction? Planning on a tune + minor bolt-ons and was wondering what actually needs to be changed to hit 400hp at the crank.

Not the DP, but the catback portion of the exhaust itself. I don't really care about making the car louder and this 4cyl doesn't sound that great regardless of exhaust.
The catback portion might pose a minor restriction at best. You wouldn’t expect a big power gain by doing either with or without a tune. 5-20 HP at most depending on exhaust and whether it’s tuned.

I forget if it was Perrin or PRL that tested intercooler, exhaust, and intercooler+exhaust and found 0-5 HP gain for intercooler, 10-15 gained for exhaust, but 25-30 HP gained for intercooler+exhaust. So it might be plausible to say there are a few minor restrictions on the car already in terms of bottlenecks.

All this said, the down pipe serves to be a bigger restriction on the vehicle as it produces the biggest power gains.

Full bolt on gives you zero horsepower gain.
I dyno my car stock and FBO without hondata..
Whp is literally same ...
Peak torque is gain 20 with FBO though.

I have
HKS intercooler with hks piping
Prl Titanium inlet
PRL high volumn intake
aFe dp and fp
Ark catback

All these without hondata gain zero horsepower and 20 torque

Has anyone successfully transported the factory exhaust in their Type R (or regular hatchback) without cutting it to pieces? I'm about to have a shop install an AWE exhaust but don't want cut up the factory exhaust. Thanks in advance for any input. I've already read this thread and saw a couple of responses but still want to know if anyone had a success story.

yes. I have seen pictures of a guy on facebook who transported a stock exhaust in his CTR (i think it wasn't modified) but the end of it was sticking out past his passenger side window.
i'll see if i can find a picture. Idk if i would do that though ... Seems almost impossible to me.

edit: nvm i am wrong. It was like an early gen CRV and the stock exhaust had a muffler delete which might have made it a little easier.

I measured it would be possible with my (new gen) MDX with seats fully down and resting on the dash. Also Oddessy could work. New Escalade and Tahoe possible. I can take another measurement if you’d like.

I have a Yonaka 3 inch exhaust from an Si coupe mated to an RV6 catless down pipe. I was pleasantly surprised how good it sounds on the R, it was not however as loud as I had hoped for at least in the cabin. My brother tells me it sounds quite loud and quite good from outside the car.

Thanks @boosted180sx and @jasonjm. I ended up cutting the factory exhaust for convenience as I don't have a truck or large SUV.

Took all the pieces (AWE Touring exhaust, includes 3" front pipe) to the shop. Everything fit inside the hatch.

Saw some interesting cars on the lot. Black CTR (not mine) just had Invidia R400 installed. Owner said it has some drone.

Factory exhaust is long! Not gonna fit inside the CTR.

Ended up cutting it in half. Will need exhaust clamp (or welding) if returning to stock.

Loaded up the two-piece factory exhaust in the trunk.

Finished product in different angles.

So far I love it. No drone in cruising speed (60 - 80). Sounds really good on acceleration. Can definitely hear it even with the windows closed but not obnoxiously loud. It feels like there's more power too. :thumbsup::thumbsup:

Factory type r exhaust is almost 11 feet..
I transport it in a dodge caravan . No problem.. it will go all the way to windshield.
My friend has CRV also fit entire exhaust

Exhaust question:

I am currently running the two tip greddy supreme. The stock dp & fp are 2.5" and I want to replace them with the pro 3" dp & fp so that I have 3" all the way back. As both the greddy and prl parts can be run with the stock exhaust, do they use 2.5" diameteris ends? So even if I installed both "3 inch" parts, where they connect would still be 2.5", therefore bottle necking the whole system?

Not sure greddy but i think prl doesnt taper down to 2.5.

I got Boost Logic w/ valved exhaust full titanium bought it for 2k at vivid racing its on the pricey side but it's one of the nicest sounding exhaust for our car and probably one of the lightest exhaust out there for fk8. valved opens up around 2-7 psi not quite sure the exact one but once it opens you will definitely feel and hear it in the cabin It gets loud its satisfying LOL but when you are just cruising its almost same as stock but better. I have 600 miles in them together with rv6 front pipe one thing I noticed is once its broken in it became so much better there was a minimal drone around 70-75 when I first installed it now it is gone. also nice thing about it is the include an adapter for stock FP and for aftermarket 3" FP and that is the only cons I have with it for the price it should've came with the front pipe but then again its full Titanium so it make sense. The quality is just top notch. its LIGHT AF!

Installed Perrin Exhaust and Perrin Rear Motor Mount inserts today. Exhaust, quiet louder than stock. Looks good to me. I'm liking it since I frequently have kids in the back seat and drone has been minimal. I don't have much to compare it to other than stock exhaust which it is much better sounding in my opinion. Next up etune since I have Hondata, PRL HVI, PRL Intercooler, Boost Tubes and now exhaust.

Anyone got experience with the Remus exhaust how the sound differ with stock frontpipe vs their own optional frontpipe?

I'm looking to buy it but can't decide if it's worth getting the frontpipe, i will only be changing it for the sound.

Perhaps anyone here got soundclips of it?

What is up all! Long time no post. Finally got got my DPW exhaust cutout done! Was trying to get The QTP to fit but DPW is the solution.. it comes with 1 remote control or you can use their app. I've had my type r since 2017 and pretty much have done full bolt on. Sound wise its loud like it should be! I also did a mid resonator delete and there is some drone with the valve open at 70 mph and up.. so I might be put that mid resonator back on.. FYI for anyone looking to do this mod. I'll try to put a sound clip on this weekend. Hope this helps guys that don't want to spend thousands of dollars on exhaust systems that aren't performance and sound justified improvement over stock.. not knocking all the awesome brands out there. This is just my opinion and what I wanted for my type R.
