hey there,
i have a vr i need a rwc and the guy picked the exhaust, i took it to an epa test and it was 104db where it needs to be around 90. I have just bought the car and it looks to have a 2.5 exhaust with 1 muffler (centre) and straight through pipe after that. I dont want to spend a lot of cash as i want to sell it soon so i dont want to buy a new stock system and ebay is pretty light on for a non irs model. Problem is the last owner modified it , welded the straight through pipe all the way back to the muffler so i cant just add a rear muffler.
I saw a thread somewhere about putting some type of restricter where the exhaust joins the cat. Will this make it quiet. I think it was some type of plate with some holes drilled in it but cant remember the details
Or if anyone in melbourne has a stock system they arent using non irs v6 vr i could buy cheap or "rent" just to pass the rwc let me know
cheers

Take it to an exhaust place, get them to cut it a bit, weld a muffler and resi in, then get them to test it. There ARE cheap ways to do it, but i don't know of them, nor do i know if they work.

easy fix. get a flange gasket for ur exhaust, take it to a machine shop, have them make up a small replica in thin mild steel without the actual exhaust centre, and drill holes in the centre. restricting the exhaust acting as a baffle, ive done it plenty of times. ur car doesnt run at its best, but only needs to pass epa right :)

i could do this very easily, if you want, just stick the flange gasket in a envelope and post it to me, let me no if you want me to.
