Exhaust questions?

[Pullstarter]

I've decided to replace the suitcase with a more free flowing muffler, replace the rear muffler with a magnaflow and maintain the rest of the stock system as I don't want it too loud. Should be done by the end of next week I hope so I'll let you know what it's like Aaron.

Right now I have cat -> rear box with 2" pipe throughout

Yeah it's droney as all hell at 2-3,000rpm. For me it's alright since I just wind the window down and turn the radio up, but like I said longer drives with others in the car it's loud as all hell.

Although to be honest, if I don't get it down this week before the drive to DOVW I most likely wont for a long while

2" isn't much IMO. I have 2" on my 1.6 (!) mk 1. Slightly oversized, but the most common suuggestion from exhaust places.

2.5" Should flow much better. Generally the resonator will quiten down teh noise at the tip a little bit, but should cut out most (if not all) of the drone.

Then it's up to choosing a muffler. Hi-Flow cat might get you a few neddies too. Not sure of the cost/performance gain factor though.

Should be able to get a standard 2" hotdog chucked in for 30-50 bucks, at about an hours work. That would be a worthy investment for the roadtrip IMO!

The whole thing depends on backpressure too. The car would rely on backpressure that may be lost with such an increase in flow, you have to be mindful of that.

Did you get it done aaron. I`d just go with the width you want and then add mufflers until its as quiet as you want.

I reckon Cat, then straight through to a generic smaller muffler in place of the hotdog and then a backbox. If its still too loud then get anothe one added after the Cat.

I am too old for loud exhausts too and have driven 2 VR6s with this setup that were very pleasant on the motorway.

Not much point going genuine and VW when you can go mild steel and generic for $300 or so all up.

Campbelltown Exhausts have always done decent work for me.

Gotta call a few people (hopefully tomorrow if I get a chance) and see what can be done on Thursday... not that I leave these things to the last minute or anything

Campbelltown Exhausts will be interesting, they get all narky about doing things legally, they didn't want to replace the old crappy muffler with straight pipe when I fixed up what was a rusty POS with holes in it.... although in this case I'm adding things

There is also Macarthur exhaust or ... ewwww... Midas

I just explain what I want and that I need no receipt and wont hold them responsible in any way. then they do what I say
