Is this cat back system from RRE a good system?

Magnaflow GS 4 Cyl Stainless Steel Cat Back Exhaust System
Strong power gains all across the RPM range, no loss of bottom end power. All stainless steel, retains the stock catalytic converter.

 

A link would be more helpful.

sorry..

 

I hadnt noticed you mentioned RRE... absolutly then.

 

ok cool thanks again..

 

I do not know if the GS has a stock mandrel bent exhaust, but I know the GT does, if your GS also has one dont spend the money buying an after market cat back, get the axel back and pull the resonators out, it will be cheaper and produce almost the same improvment

 

Das ist sehr gut!
