Hello all, I've carried out a fair few searches on these forums (awesome resource! ) before pinning down the fact that I need a standard exhaust to replace the horrendous Sportex frankenstien job my 205 Gti came with. I have a GTi-6 engine with "4903106" Catcams installed with a standard manifold and I've narrowed it down to two choices: Option 1 - Non-Cat Phase 2: http://www.buypartsby.co.uk/details/PEUGEOT/205/1.9/1992/__/79/630186/exhaust-part/ (circa £150 for 2 piece) Option 2 - Cat-Compatible Phase 2: http://www.buypartsby.co.uk/details/PEUGEOT/205/1.9/1992/__/79/630187/exhaust-part/ (circa £65 for two pieces - minus cat section) Now the issue for me is that regardless of what I choose I will have to instruct the exhaust fabricator to knock up an adequate downpipe from the GTi-6 manifold to the centrebox, so Option 1's front pipe will certainly require chopping. However Option 2, the "Cat-Compatible" system, seems to make more sense seeing as it's not inclusive of a downpipe thus no chopping required and it's cheaper overall. However I'm hoping someone could inform me whether there is a difference in the centrebox design (baffling) between the cat and non-cat centreboxes? In other words Option 1, seeing as it's for a non-cat system, will it have superior baffling than Option 2 which assumes a Cat would be in front of it? Also does Option 1 have the downpipe split all the way back to the centre box? I ask because it's unecessary for GTi-6 application therefore making the whole length of the front pipe an unecessary expense (again making Option 2 more attractive). However If Option 1 does indeed have superior baffling and the downpipe spit is only to the step down section I'm willing to pay the extra for it as I cannot stand the boom from 3-4k! Please let me know guys, the drone of the current system makes the car far too embarrassing to drive.
