Would you get performance gains from a standard aero down pipe with the cat removed which would increase the gas flow? as oposed to using a 3" down pipe with race cat
Well, as the two cats in the standard Aero DP are not removeable, you would have to physically cut them out of the DP and weld in new pieces, which isn't overly practical, and the standard DP is still restrictive in it's shape compared to an aftermarket 3" DP.james-aero said:Would you get performance gains from a standard aero down pipe with the cat removed which would increase the gas flow? as oposed to using a 3" down pipe with race cat
There trouble is the cost of finding someone (unless you have the skills and equipment) good enough to cut up the standard DP and accurately weld some new sections in would probably more than just buying a 3" DP, especially as you would still have the 90deg restriction out of the turbo. Also, with no cat the ECU is almost certainly going to throw a check engine light because of the 2 x 02 sensors either side of the cats....?james-aero said:Im just looking for some options to keep the cost down of tuning my car ie making a standard down pipe into a straight through one :lol: being a young lad its costing me enough to run the car so budget mods are needed
The first O2 sensor is before the first cat, as long as you had second one after the cat under the oil pan everything should be ok. This is how the genuinesaab one runs. This is also how the one I'm getting made up shortly will be too.aeropilot said:There trouble is the cost of finding someone (unless you have the skills and equipment) good enough to cut up the standard DP and accurately weld some new sections in would probably more than just buying a 3" DP, especially as you would still have the 90deg restriction out of the turbo.

Unfortunately, there really isn't such a thing as budget mods for Saabs here in the UK, especially on T7 cars.
Thats a good Idea I shall talk to them.Thanks.XAAMOTTOMAAX said:SBM, if that quote from Lou's is not for stainless, find out how much he wants for full stainless steel and go that route.
That includes the 3inch dp and installed? or 375 just to install it?SaabBlackMan said:I am actually going to have a 3inch DP installed on saturday at Lou's Custom Exhaust Quote is 375 which isnt a bad deal at all. 3inch Cat Converter as well.
