I have a HOLE

Driving home tonight i hear a bang on the back of my car, turns out a bit of steel hit my muffler. It has a tiny hole just enough to peirce through, i patched it up but with all small holes in muffler they get bigger.. So in the next 4-6 weeks i will buy a new muffler, im looking at a Magna flow muffler (sorry guys no CBE not interested) MagnaFlow Exhaust Products - For Trucks, Suv's, American Muscle, Diesel, & Sport Compact Vehicles

how restictive is the Gen2 muffler? Since this flows better do you think it will upset my tune?

might over boost more not sure

that really sucks...
Personally i think the Muffler might be more restrictive than people think.
Considering the power/torque Wookiebmx's car made with an aftermarket exhaust.
Im sure it wouldnt cause damage, but surely its got to throw your tune out.
Id speak to Tony @ Tunehouse about his opinion, Being that one of their very regular customers (their development car) has the HKS back section exhaust/muffler, He will know for sure.
being you only got tuned yesterday i would not be overly keen to changing any hardware,
Pretty sure @2XS has a used MPS back section at a good price. That would be what id be doing anyway.

Luke, I have a custom 3" system with a Magnaflow muffler. In all honestly I could have just gone axle back and kept the OEM resonator (to save $$$), but it wasn't a lot more

I think the car sounds horn. It's not loud at start up or around town, but when you're on it, oh yeah!

I've had a few passengers, they seemed to like it!

Thanks Cton, i have sent a pm to Chris to find out for me. I will see what they say if it requires a retune i will see how long my repair job lasts LOL

Another option... it comes up for service soon so send it down for service Jim can have a look at it all, hmm too many options.. DAMN hole why now y not few months down the track :P or 2 weeks ago lol

I say just replace it, its not going to throw your tune out by any noticeable amount, if at all.
Its just the rear muffler yeah?

Yeah just the rear muffler.

I'm sure there might be a few members selling their stock muffler after an upgrade. I got $200 for mine.

Its not worth tuning for

yeah, not worth retuning.
The std Gen 2 muffler is very restrictive.
Just take a look at the gold (driven hard it goes black) patch in the centre of the muffler, that's a hot spot (restriction)

I have a std gen 2 muffler for sale on my website.

Or, go the Magnaflow muffler, that's what I generally use aswell

I also have a Gen 2 CBE coming soon too. I have the centre section already, I juts need to fabricate a rear muffler section and jig it.

Rang TH and spoke to Tony, He advised 90% of the time its ok but seeing im running standard muffler get it checked. Jim will power run the car if all good nothing more will be done. If it needs to be adjusted will be dyno run time by the hour.
