been offered a P1 exhaust for my wagon

just wanna know if this would make it quite

got a 4 1/2" straight thru but it is just to loud

do you think it would give me more power its a standered exhaust with cats and silencers

any info would be appriciated

cheers

I take it you mean you have a 4 1/2" back box.............your only gonna get power loss from taking off a straight though (- 2 cats) and putting on a standard ( plus 2 cats)..........will defo be quieter though..........however to go from strraight through to an exhaust with the cats will confuse the ecu and should really get a remap.

Leave the exhaust as it is and change the back box for something quieter like a classic prodrive item

P1 exhaust only has 1 cat on the downpipe but if you have a full de cat then you're going to need to re map.

Just get a different back box

would the P1 backbox fit straight on to it
