What is the best pipe to get the most out of the flat 4. There is a blue 02 saloon going about chelmsford sounds loverly. If anyone nows what he is running?

 

A lot depends on how loud you want to go, I had a 3 inch system with sports cat which sounded nice but after 6 years two mountings snapped. So went de-cat but 3.5 inch, it is loud which for a daily drive would be unsuitable but for a bit of fun is fine. It does have a adjustable bung in the tail pipe so can be made to be more friendly.

 

fully decatted prodrive or magnex are perfect imo, i hate stupidly loud tinny exhausts on imprezas

 

I have the prodrive system will decating the up pipe improve the sound. Will I have problems with mot?

 

Is your car newage?
If you have the full prodrive system it prob has a resonator in the mid pipr , if u wanted more noise you could have them taken out. The prodrive and magnex ones are made with good thickness of metal and extra baffles so they give a more meaty muffled sound as opposed to the high pitch tinny noises some systems give....all imo of course but im mid 30's now and loud exhausts arent my thing anymore :-)

 

Yes mate 04 wagon ppp just want a little bit more of that noise while.still being Ok for mot bit more power would be nice aswell.

 

nur spec r......

 

Genuine STI Genome, trouble is they don't come cheap ........

 

just got my car back today after fitting a 3" decatted H&S downpipe and a 2.5" decatted prodrive cat back. sounds perfect, very subtle just pottering around and idling but really barks on boost

 

I've had a few over the years, Prodrive is quiet without a decat or de-res centre section and sports cat, Afterburner gives a nice deep rumble but can be a bit loud, Blitz NUR is just mental on a decat way too loud, Japspeed was a bit tinny and raspy, best for me is my current 3" full decat Miltek @93db at 4.5k RPM quiet when it needs to be and roars when pushed

 

i think i'm going to get an H&S

 

For me its the Blitz Nur spec R with full decat. Ive heard most and most members in wmi will prob agree.

 

How about mot if I put 100 cell in down pipe and decat up pipe will it go threw?

 

You said you have ppp then you already have the sports cat mate just change out the centre for straight through section and you will have a nice sounding system without being to loud

 

+1 for H&S mate, I have just had a 3.5 inch rolled quad fitted at their workshop in Basildon which is very close to you and they don't charge for fitting. On my old car I went for the H&S 4.5 inch slash cut angled exit, sounded awesome. Speak with Ian @ H&S Tel - 01268 727256

i have a milltek cat back system on my 04 wrx wagon it sounds good not the typical tinny kinda sounds of some subarus very deep and throaty like it look it up mate

 

What are everyones views on the Afterburner Vortex and Raptor exhausts made by H&S?? I've a Scorpion on mine at the moment, came with the car but I would like an angled exit and possibly a deeper note. Not sure if the Raptor is going to be silly loud? I live in a built up area and although when I come home late at night I keep the speed right down to a minimum to avoid waking the neighbours up (I don't want the aggro)

The Afterburner Vortex is a 2.5" system and the Raptor is a 3"

 

I have a Cobra 3" cat back non resonated system, nice deep burble. Click on the link below because they have a video of the system in action!

I've got a kakimoto full system on my v5 sti and it unbelievably loud.

 

Started with a H&S with Prodrive downpipe, the rest decatted. Was a good blend of sound etc. Then tried a Cobra Racetube for a bit of fun....that's all it was...sounded mental, but too ridiculous as a whole.
Now with a NurSpec-S, it's absulutley brilliant, by far the best I've had. Sounds perfect for the flat4, and it looks top stuff too, very nice exhaust.
I don't think it's that stupidly loud either, depends if you driving it in high revs round the town?, motorway speeds revs are pretty low at 70mph so again not too bad.

 

Miltek 2.75 with centre de-res.
simples!

 

H&S decat system finished off with a Genome silencer . Prodrive silencer with an unresonated centre pipe sounds nice too, nice and subtle.

 

I have a 2005 sti PPP, will replacing the centre pipe with unresonanted need a map tweek? it is running on the standard ppp ecu.

 

Got a 3" full decat milltek . Lovely exhaust and noise is spot on for even a daily car

 

Best invidia N1,deep as nur R but more burble but those 2 are loud.
I had headache after half mile trip with N1 fitted to my wrx ppp
