The Toffinator Posted July 17, 2012 Share Posted July 17, 2012 Currently have a HKS Silent HI-Power on my glanza, fair few engine mods and the noise is lovely when on boost, but its still pretty quiet, If i remove the midpipe it has will it be unbearable in the car for longish journeys etc? I want a louder car, but dont want it to be a compromise.Opinions? Quote Link to post Share on other sites
Amjad Posted July 17, 2012 Share Posted July 17, 2012 Completely remove the pipe or just the silencer? Quote Link to post Share on other sites
The Toffinator Posted July 17, 2012 Author Share Posted July 17, 2012 Just remove the midpipe dude. Ie straight pipe to the backbox Quote Link to post Share on other sites
A L 3 X Posted July 17, 2012 Share Posted July 17, 2012 Silencer then? ;)All depends mate, had a powerflow that had no silencers except the backbox, but small pipe work and that was almost silent in idle, myFujitsubo however has the backbox, plus two more silencers but 2.5" piping and that's a fair bit louder.

The Toffinator Posted July 17, 2012 Author Share Posted July 17, 2012 Silencer/Midpipe same thing! Sure midpipe is the correct term but meh . And hmm, currently mine is nice on tickover, alot quiter than my n.a was (Obviously) But it sorta burbles, i just want more of what id does now! Quote Link to post Share on other sites

Liam_D Posted July 18, 2012 Share Posted July 18, 2012 I have no boxes, and mines only loud on boost really Quote Link to post Share on other sites
The Toffinator Posted July 18, 2012 Author Share Posted July 18, 2012 Thanks lads, and yeh morgey no worries dude! Liam thats what i was thinking, they dont have much noise to generate so it shouldnt be too bad. Might give it a shot! Quote Link to post Share on other sites
Max9650 Posted July 19, 2012 Share Posted July 19, 2012 do it asap and let me know how it goes haha, i just think the exhaust note might change slightly, i find that when i really rag the car the note goes really deep as it is - dont really like it overly :/ Quote Link to post Share on other sites
pick1 Posted July 19, 2012 Share Posted July 19, 2012 I have no boxes, and mines only loud on boost really Urs sounds epic on boost lol Quote Link to post Share on other sites
Liam_D Posted July 19, 2012 Share Posted July 19, 2012 Cheers dude Its mainly noise from the screamer though Quote Link to post Share on other sites
DavidAshton Posted July 19, 2012 Share Posted July 19, 2012 My first Glanza had a HKS Hi-Silent and I hated how quiet it was. I got the middle box cut out and a straight through pipe put in place and it sounded so much better in every aspect. Here is a quick video I found that I had of it. I can't remember the exact setup at that time but i know it was cat and middle box removed.[media]http://www.youtube.com/watch?v=8GqEpzIVFgQ&feature=youtu.be Quote Link to post Share on other sites
FrancyGlanza Posted July 19, 2012 Share Posted July 19, 2012 I wana do this tomaz for my pro racer but will it affect performance wise ? Quote Link to post Share on other sites
The Toffinator Posted July 20, 2012 Author Share Posted July 20, 2012 That sounds lovely dave, was it much dronier in the car etc? And was it still possilble to pootle around and be reasonably quiet without being obtrusive? Quote Link to post Share on other sites
Starlet__SR Posted July 20, 2012 Share Posted July 20, 2012 I ran a 2.5 in pipe straight through from turbo back and it was lovely, even on boost. Long journeys were a doddle lol.Day Quote Link to post Share on other sites
DavidAshton Posted July 20, 2012 Share Posted July 20, 2012 That sounds lovely dave, was it much dronier in the car etc? And was it still possilble to pootle around and be reasonably quiet without being obtrusive?It was no louder in car than before, well unless you had windows down and gave it a boot full. Just pottering about was fine I never got any bother off anyone. Quote Link to post Share on other sites
The Toffinator Posted July 20, 2012 Author Share Posted July 20, 2012 May need to get it done, only downside is i have heatwrapped the exhaust so i would have to cut it back each side first Lol Quote Link to post Share on other sites
The Toffinator Posted November 3, 2012 Author Share Posted November 3, 2012 Got this done today, 2.5inch straight section of stainless. Very pleased with how it sounds, not mental loud, its the same on tickover and light throttle, on boost its a bit harsher and you get a few pops and bangs, Its spot on, brought the exhaust to life yet its not obtrusive!

daniel_g Posted November 4, 2012 Share Posted November 4, 2012 Anyone done this to a 5zigen system ? The mid silencer box looks pretty large and restrictive. Quote Link to post Share on other sites
