Hi flow cat - Power

Mandrel bent - Power

a good cat back - Power

Muffler - +10 on wanker scale and louder..

and yes.. mufflers are included on cat backs..

Personally.. go the second of your options.. i.e. Hi flow cat (may now have MASSIVE benefits on a low power NA car).. mandrel bent 2.5" and a muffler.. this it would suite your wants best

dont know much about Xforce products.. or their quality..

Best to do research.. Save and get good quality (like coby) headers.. a full manderl bent 2.25 - 2.5" exhaust.. cat.. and muffler..

  • 1 year later...

didn't want to start another new thread on a worn out topic so i thought i'd re-use this one

i've just had a new intake and full exhaust put on my car. picked it up this morning from my mate after i've come back from a weeks holiday.

driving the car home 20mins has left my head feeling numb and ears ringing from the loudness and the drone.

the full exhaust comprising of HPC Coby's, high flow cat, custom mandrel SS 2.5" exhaust, oval muffler with twin tips for factory look. I'm seriously regretting it at the moment and want my factory exhaust back on.

it's been suggested to me to put an oval resonator in but i'm not sure if that alone will be enough to quieten the noise and remove the drone. i'm also thinking a new muffler as well.

so i seeking some help from those who have actually had this dilemma and what did you do to fix it?

Reggie.

Ive got a 2.5" catback mandrel bent exhaust custom made.

cant even hear it on idle, but it begins to roar after 3000rpm.

i LOVE it because people are astounded about the difference between how quiet it is during idle, and how nice the grunt is at high rpm.

going to get a new high flow cat soon...not sure If i want to buy Xforce though...

Reggie ive got a resonator on mine, works a treat.

p.s. mine droned quite a bit for a few weeks....so give it sometime and see if it quietens down after a while...

When I was talking to one of the guys at Rob Bliss Exhaust a few months back, he said that oval barrel twin tip on an N/A will drone and they haven't been able to get rid of that drone. Seems like it's a characteristic of that muffler.

I was thinking of going for the twin tip factory look as well when I end up doing my exhaust, but the noise I guess will offset that factory like side of it. You could always get a factory twin tip of a GTR, that should flow plenty for an N/A and keep things quieter.

when i first put the 2" system on the SSS i only had a lukey muffler on the rear and it was noisey as hell but sounded great. the guys fitting it got me to take it for a spin round the block to see if i wanted to quiten it down. i took it for a spin, and as much as i liked the sound i knew that mr policeman would bend me over and insert his nightstick into a certain orrifice if i left it that loud, and also on trips it would piss me off, so we put eith a 12 or 14" resonator (hotdog style) in the centre and it made it much better. although it did lose a bit of bark.

so a resonator alone won't be enough to tone down my exhaust volume and drone?

i.e. get it under the legal db level?

i found a hot dog keeps it down nuff long as ya aint got a cannon on the back lol, though it does drone quiet abit but tis bearable :P... mild steel defo ova stainless tho!!! hahaha less ya want it 2 sound like a tin can

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
