Muffler Suggestion?

[dk.boi]

Hi,

Ive recently bought a r34 25gt, the previous has removed the original muffler and replaced it with some cheap dodgy one. I am planning on replacing it.Do you guys have any suggestion from something that is value for money? I am also on my red p's. will I become cop bait, if i change it?

Thank you

If I was you I would be replacing the system from the cat back. You'll be able to either get a custom one made up or perhaps find an aftermarket japanese system on the forums etc.

Most people will tell you not to go any bigger than a 2.5" system on an NA car like yours however I'm running 3.5" HKS on my RB25DE and my mate has a Blitz system which is 3" and they both perform fine. That said, my brother is using a custom 2.5" catback system and I can definitely notice more response and power down low in the rev range.

How much do you have to spend? A custom mandrel bent catback from an exhaust shop will probably charge you around the $500 mark give or take a little?

Hope that helped a bit.

i'd go something like a 2.5" lukey performance flow. it's an oval muffler and not a cannon, so should help reduce police attention. also being an oval muffler it will be a touch quieter than a cannon. i recently got one put on my SSS pulsar and along with 2.25" piping (and 2.5" muffler) it is quieter than the old 2" system that was on there with a smaller bodied 2" oval muffler. also shouldn't cost that much to get fitted. i was quoted $120 for muffler and fitting at my local muffler place, but ended up being a bit more cause i got the extra piping done (ended up being $170 all up)

Hooker Aero Chamber mufflers are excellent and around $150 from VPW

I love magnaflow mufflers, look and sound. Oval straight through centre offset, they're a mandrel preforated pipe that are fibreglass packed and use absorption to reduce noise, and that type of muffler (straight through) gives the best performance (minimal backpressure).

I've got a satin stainless one at the rear, and the biggest (longest) hotdog resonater i can find before the diff. It's a 3" system on my RB30DE, sounds unreal, you'd obviously be after a 2.5" though.

My car is quite loud (however its slightly different to a standard rb25de) but has absolutely no drone, it just rumbles down low and screams with revs. I'll change the hotdog to a centre/center straight through at somepoint, just to quieten it down so its more street drivable (when i want to street drive it, down the track).

the performanceflow muffler is pretty much the same as the magnaflow but it has a bigger body on it so it is quieter. still use the centre/offset configuration and the perferated straight through pipe. very much like the ultraflow
