Catbacks

[Karl]

Went to exhaust place today asking for quote for 3 inch stainless cat back.
He explained to me that a high revving require slight back pressure and recommend no more then 2 1/4 inch.( Is This True)

And he also said that ill be better goin for a premade cat back system. Wonder if any one has driven or brought a J's racing " http://cgi.ebay.com.au/ws/eBayISAPI....=STRK:MEWAX:IT "
or Mugen " http://cgi.ebay.com.au/ws/eBayISAPI....=STRK:MEWAX:IT "
or Spoon N1 " couldn't find link " ... Or recommends any other premade cat back system

Thanks for the offer. But i like things brand new... Any idea's about what i said above????

2 and 1/4 will give heaps of backpressure.... and 3 inch is a bit overkill if ya ask me...

[Karl]

over kill.. meaning waist of money.. He was telling me if i were to go more then 2 1/4 ill actually loss power.. As a high reving engine require back pressure !!!!!!!!!!!!!

2.25-2.5 for na. unless you're boosted, u will lose power with 3.
