I'm going to order the Stan's 4" system pretty soon, and I was wondering if I will have to get the downpipe cut back to fit with the HX-35. If so, exactly how much of the downpipe will need to be cut off? Once it has been cut and the flange is welded back on, should everything fit and line up Ok?

 

Stan's exhaust fits very well with an hx-35. No mods are needed, the downpipe is short enough so it won't interfere with the firewall.

 

The expansion part from the flange to the 4" tubing on Stan's downpipe is much shorter than the stock DP. I had problems before with the stock DP sealing because it was too long and running into the firewall. When I put Stan's system on, it bolted up to my HX-35 and fit like a glove.

 

Thanks a lot for the help. I was worried about this, but not anymore. I will be calling Stan's in the near future.
