Extractors with standard exhaust?

[webbiegareth]

Hi all,

I need a complete exhaust system for my girlfriend's car - manifold, cat and cat-back (it's leaking all over the place). It needs to be quiet as I want to pass a roadworthy it it, and it doesn't really need to be for performance.

But if I can get the go-fast bits for the same price as the stock bits, I will.

I've picked up a set of pacemaker 4499's for a hundred bucks, I was going to get a 2nd hand standard manifold for $50 - $80 anyway so I figured why not.

For the cat... I'm having trouble even finding a standard cat for a decent price, those "Venom" brand hi-flow cats are just as cheap it seems! I was thinking of buying the 200CPSI version (i.e. not the higher flowing 100CPSI one) since it SHOULD be quieter. Or maybe the 400CPSI version? They're not really high flowing anymore, but at that CPSI are the still better than the stock standard ceramics? They're about $180.

I almost bought a cheap catback system from this site a while ago, but due to unexpected circumstances (family member falling ill), I had to travel quickly and was offline for a long while. :(

I'm back though

I'm having trouble with finding a decent cheap cat-back system. A Redback system with the twin mufflers and what looks like a small resonator is around $320 on Ebay. People often talk about catbacks on ebay for <$200, but those seem to be the straight-through system which I'm not interested in (no way would it pass a roadworthy). I'm hoping the two muffler with rear resonator is what I need.

So, unless I can find a 2.5" catback system that's cheap AND quiet, I'm looking at putting another stock system back on. I can get a 2nd hand but almost new standard catback exhaust for $50.

Would it be possible to join the 4499's, a high flow exhaust and a standard catback system together? Will it perform better than a standard stock system, or would mixing parts like this ruin performance and economy?
