ive got a 3inch dump, gutted cat (hollow), 3inch catback with hotdog and JunBL muffler with twin flutes and a ECV in between the reso and muffler. not overly loud, bit quiter than my old system with a straight through catback from a stock dump and cat. ECV makes the system pretty close to stock noise. once i shut that on the cops dont really take notice. also the twin flutes are better for cop attention than a big cannon at the back.

3" tanabe medallion catback and hollow cat.....needing split front/dump pipe and hiflow 3inch cat, atm though its nice not overly loud until it comes onto boost :D

LOL nisskid, i had the same stock front/dump and cat witha straight through catback, was LOUD, but surprisingly 6months driving didnt get pulled over once :)

If you already got a 3" all the way why do you wanna change it? Sounds like a waste of money to me. I got a blitz nur spec r cat back so far. Got a metal cat at home but still waiting to get the d/f pipe. The sound is nice and deep. When there are cops I gotta keep it at very low revs other wise get pulled over (happened once so far).

sounded good tho i rekon, my mates now got the exhaust, it was actually 3.5" straight through, did someone say drone? but when u opened it up, couldnt beat the sound.

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
