So I'm installing cpe catless dp's on my 335i N54..
How much room should be between were the dp meets the ehxuats? By the bolts,, I have about 2 credit cards worth of room between them.. Is that normal?

Are the gasket in there yet?

Yup everything is bolted up and tight.. Just about 2 credit cars or 3 worth of room btween them, but there stiff and tight I don't see them moving juss wanted to see what everyones experience is?

As long as they're not rubbing, you're fine.

There should be almost no gap after the bolts are tightened...If there is then you are going to get a helicopter exhaust leak type of sound..Release the rear exhaust bracket so there is room to slide the back part of the exhaust upwards to close that small gap and then retighten the back exhaust bracket.

Thanks for the input, sorry if I explained it wrong, but I'm talking about the space btween the two seperate pipes, I bolted everything up...

hahah Thanks man!!!! im gonna go take it out for a drive now, double check everything was tight, and everything had clearance.. wasnt a easy job and because i am so anal that didnt help any.. but i have to say the CPE's for fitment are good from what i can see.
Car is def louder.
Time to go see what catless DP's are all about.

I'm glad you got it done. There is a sense of accomplishment in installing your own mods. I changed my dp's in the middle of the Tx summer. Won't ever make that mistake again.

DP's are a tough DIY. As long as you got them in tight and they aren't touching you should be ok. Just make sure you don't have the clamp in the way of the wastegate arm/bolt. I made that mistake and had to basically do it all again to fix it.

Thanks alot man.. Yea def feels good doing it yourself and making sure everything is the way you want it. Im a big DIY guy so i love finishing the job myself. LOL in the middle of the TX summer, that sounds like big challenge.

Yup i double checked. i actually took pics of the sensors and the way the clmaps were on the Stock DP's then when i threw the catless CPE's on, i looked at the picture and just position the same way, everything running great.



Thanks to everyone for the help.
